If that user can view kube-apiserver logs when the log level is set to 10, they can view the redirected responses and headers in the logs.
This issue has been rated **Medium** (https://www.first.org/cvss/calculator/3.1#CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:L/I:N/A:N) (4.1), and assigned **CVE-2020-8561**
### Am I vulnerable?
You may be vulnerable if `--profiling` is enabled on the kube-apiserver and actors who control a validating or mutating webhook can access the kube-apiserver process logs.
#### Affected Versions
This issue affects all known versions of kube-apiserver.
### How do I mitigate this vulnerability?
This issue can be mitigated by not allowing kube-apiserver access to sensitive resources or networks, or to reduce the “-v” flag value to less than 10 and set the “--profiling” flag value to “false” (default value is “true”). Setting the profiling flag to “false” prevents users from dynamically modifying the kube-apiserver log level, and the flag value Webhook requests may still be redirected to private networks with a log level less than 10, but the response body will not be logged.
### Fixed Versions
There is no fix for this issue at this time.
### Detection
Examining kube-apiserver log responses is the only known method of detection for this issue.
If you find evidence that this vulnerability has been exploited, please contact [email protected]

] | A security issue was discovered with Kubernetes that could enable users to send network traffic to locations they would otherwise not have access to via a confused deputy attack.
This issue has been rated **Low** severity ([CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N](https://www.first.org/cvss/calculator/3.1#CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N)), and assigned **CVE-2021-25740**.
### Am I vulnerable?
If a potential attacker can create or edit Endpoints or EndpointSlices in the Kubernetes API, they can potentially direct a LoadBalancer or Ingress implementation to expose backend IPs the attacker should not have access to.
Importantly, if the target’s NetworkPolicy already trusts the Load Balancer or Ingress implementation, NetworkPolicy can not be used to prevent exposure from other namespaces, potentially bypassing any security controls such as LoadBalancerSourceRanges.
This issue is a design flaw that cannot be fully mitigated without user-facing changes. With this public announcement, we can begin conversations about a long-term fix.
#### Affected Versions
All Kubernetes versions are affected.
### How do I mitigate this vulnerability?
There is no patch for this issue, and it can currently only be mitigated by restricting access to the vulnerable features. To mitigate the exposure, we recommend restricting write access to Endpoints and EndpointSlices by updating the system:aggregate-to-edit role using the [attached file](https://github.com/kubernetes/kubernetes/files/6823580/aggregate_to_edit_no_endpoints.yaml.txt). This will remove write access to Endpoints from the admin and edit roles:
```shell
# Allow kubectl auth reconcile to work
kubectl annotate --overwrite clusterrole/system:aggregate-to-edit rbac.authorization.kubernetes.io/autoupdate=true
# Test reconcile, then run for real if happy
kubectl auth reconcile --remove-extra-permissions -f aggregate_to_edit_no_endpoints.yaml.txt --dry-run
kubectl auth reconcile --remove-extra-permissions -f aggregate_to_edit_no_endpoints.yaml.txt
# Prevent autoreconciliation back to old state
kubectl annotate --overwrite clusterrole/system:aggregate-to-edit rbac.authorization.kubernetes.io/autoupdate=false
```
Note: This will prevent new versions of Kubernetes from reconciling new default permissions to this role. No new default permissions have been added to this role since v1.14.0, but we recommend you remove the autoupdate=false annotation as soon as a fix or other mitigation is possible.
For use-cases that need to edit these resources, we recommend creating a new purpose-built Role with the desired permissions, and using it only for those cases.
### Detection
Services with an empty selector rely on custom endpoints and are vulnerable to the attack described above. We recommend manually auditing any such usage. The following kubectl command will list all Services in a cluster with their selector:
```
kubectl get svc --all-namespaces -o=custom-columns='NAME:metadata.name,NAMESPACE:metadata.namespace,SELECTOR:spec.selector'
```
Note: Some Services without selectors specified may have their Endpoints managed by other controllers or tools. For example, endpoints for the default/kubernetes Service are managed by the Kubernetes API Server.
If you find evidence that this vulnerability has been exploited, please contact [email protected]
#### Additional Advisory
A similar attack is possible using Ingress implementations that support forwarding to ExternalName Services. This can be used to forward to Services in other namespaces or, in some cases, sensitive endpoints within the Ingress implementation. If you are using the Ingress API, we recommend confirming that the implementation you’re using either does not support forwarding to ExternalName Services or supports disabling the functionality.

This issue has been rated **High** ([CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H](https://www.first.org/cvss/calculator/3.1#CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)), and assigned **CVE-2021-25741**.
### Affected Components and Configurations
This bug affects kubelet.
Environments where cluster administrators have restricted the ability to create hostPath mounts are the most seriously affected. Exploitation allows hostPath-like access without use of the hostPath feature, thus bypassing the restriction.
In a default Kubernetes environment, exploitation could be used to obscure misuse of already-granted privileges.
#### Affected Versions
v1.22.0 - v1.22.1
v1.21.0 - v1.21.4
v1.20.0 - v1.20.10
<= v1.19.14
#### Fixed Versions
This issue is fixed in the following versions:
v1.22.2
v1.21.5
v1.20.11
v1.19.15
### Mitigation
To mitigate this vulnerability without upgrading kubelet, you can disable the VolumeSubpath feature gate on kubelet and kube-apiserver, and remove any existing Pods making use of the feature.
You can also use admission control to prevent less-trusted users from running containers as root to reduce the impact of successful exploitation.
### Detection
If you find evidence that this vulnerability has been exploited, please contact [email protected]
### Additional Details
See Kubernetes Issue #104980 for more details.

**Describe the bug**
A heap-based buffer overflow was discovered in libgpac. The issue is being triggered in the function OD_ReadUTF8String() at odf_code.c
**To Reproduce**
Steps to reproduce the behavior:
1. Compile according to the default configuration
```bash
$ CC="gcc -fsanitize=address -g" CXX="g++ -fsanitize=address -g" ./configure --static-mp4box
$ make
```
2. execute command
```bash
MP4Box -hint $poc
```
[poc](https://github.com/14isnot40/vul_discovery/blob/master/OD_ReadUTF8String_hbo) can be found here.
**Expected behavior**
An attacker can exploit this vulnerability by submitting a malicious media file that exploits this issue. This will result in a Denial of Service (DoS) and potentially Information Exposure when the application attempts to process the file.

**Describe the bug**
A heap-based buffer overflow was discovered in libgpac, during the pointer ptr points to the wrong memory area operation. The issue is being triggered in the function gf_hinter_track_process() at isom_hinter_track_process.c.
**To Reproduce**
Steps to reproduce the behavior:
1. Compile gpac according to the default configuration
```bash
./configure --extra-cflags="-fsanitize=address,undefined -g" --extra-ldflags="-fsanitize=address,undefined -ldl -g"
```
2. execute command
```bash
MP4Box -hint $poc
```
[poc](https://github.com/14isnot40/vul_discovery/blob/master/gf_hinter_track_process_hbo) can be found here.
**Expected behavior**
An attacker can exploit this vulnerability by submitting a malicious media file that exploits this issue. This will result in a Denial of Service (DoS) and potentially Information Exposure when the application attempts to process the file.

] | **Describe the bug**
A heap-based buffer overflow was discovered in tcpreplay-edit binary, during the pointer 'ip' dereference operation. The issue is being triggered in the function randomize_iparp at edit_packet.c:1032.
**To Reproduce**
Steps to reproduce the behavior:
1. Compile tcpreplay according to the default configuration
```bash
./configure CFLAGS="-g -O0 -fsanitize=address"
```
2. execute command
```bash
tcpreplay-edit -r 80:84 -s 20 -b -C -m 1500 -P --oneatatime -i lo $poc
```
[poc](https://github.com/14isnot40/vul_discovery/blob/master/tcpreplay/tcpreplay-edit/pocs/hbo_randomize_iparp) can be found here.
**Expected behavior**
An attacker can exploit this vulnerability by submitting a malicious pcap that exploits this issue. This will result in a Denial of Service (DoS), potentially Information Exposure when the application attempts to process the file.

exploitation of vulnerability:
1. Enter the directory mode of the extension module
2.In directory mode, click return to the previous directory
3.Discover parameters by capturing packets "dir=.",Change the parameter to "dir=.."
After the directory overflow, more delete options were found than before
4.Remove robots.txt as a test,Click delete robots.txt
Delete the success!
5.We discover parameters by request："url=../robots.txt"，Let's try to change the path to something else
6.A new test.php file was created on disk for the test
7.Change the parameter to "URL =../../../../../../../../test.php
Delete the success！Test.php cannot be found.
The POC is as follows: The path and parameters are determined according to the actual situation

```
function set_cache($filename, $data, $dir = '_cache_'){
static $_dirs;
if ($dir == '') return FALSE;
if (!preg_match('/([a-z0-9_]+)/i', $filename)) return FALSE;
$cache_path = CACHE_ROOT . $dir . '/';

```
2.
The set_cache method is called in the set method of the \coreframe\app\attachment\admin\index.php file, and $GLOBALS['setting'] has not been filtered，so anything can be written to the php file.
```
public function set()
{
if (isset($GLOBALS['submit'])) {
set_cache(M, $GLOBALS['setting']);
MSG(L('operation_success'), HTTP_REFERER, 3000);

set_cache(M, $setting);
}
include $this->template('set', M);
}
}
```
3.
Finally, on line 21 of \coreframe\app\attachment\admin\index.php, a php file that can write arbitrary content will be loaded.
` $this->_cache = get_cache(M);`

] | - [x] I looked for a similar issue and couldn't find any.
- [x] I tried with the latest version of GPAC. Installers available at http://gpac.io/downloads/gpac-nightly-builds/
- [x] I give enough information for contributors to reproduce my issue (meaningful title, github labels, platform and compiler, command-line ...).
Step to reproduce:
1.get latest commit code (GPAC version 1.1.0-DEV-rev1221-gd626acad8-master)
2.compile with --enable-sanitizer
3.make 5 dirs which every of them has a large name(length=255), this makes the file's abs-path lengh larger than 1024, we called it large.nhml
4.run MP4Box -add {path to large.nhml} -new new.mp4

Different from issue 1911, the overflow memory is related to szXmlFrom parameter. The szXmlTo para has the same problem, please fix them together.
Buggy code at dmx_nhml.c:1008:
```
static GF_Err nhmldmx_send_sample(GF_Filter *filter, GF_NHMLDmxCtx *ctx)
{
else if (!stricmp(att->name, "xmlFrom")) strcpy(szXmlFrom, att->value);
else if (!stricmp(att->name, "xmlTo")) strcpy(szXmlTo, att->value);
}

I found a cross-site scripting attack on the login page http://localhost:800/admin/login
cross-site scripting is a vulnerability that allows an attacker to send malicious code(usually in javascript form)
to another user
Because a browser cannot know if the script should be trusted or not,
it will execute the script in user context allowing the attacker to access any cookies or sessions tokens retained
by the browser.
### Steps to reproduce the problem
1. open login page http://localhost:800/admin/login;
2. enter the username place ``admin"><img src=x onerror=alert(1)>`` and enter password
3. trigger the malicious javascript code

] | **Summary**
stb_image's HDR loader in versions 1.33 to and including v2.27 parsed truncated end-of-file RLE scanlines as an infinite sequence of zero-length runs. An attacker could potentially have caused denial of service in applications using stb_image by submitting specially constructed HDR files.
CVE number: [CVE-2021-42715](https://nvd.nist.gov/vuln/detail/CVE-2021-42715)
**Describe the bug**
In stb_image's HDR reader, loading a specially constructed invalid HDR file can
result in an infinite loop within the RLE decoder.
This issue includes a fix in pull request #1223, and a proof of concept file that
can be used to reproduce the crash. We're reporting this on GitHub Issues
following the guidance in issue #1213.
The issue occurs in [this loop](https://github.com/nothings/stb/blob/master/stb_image.h#L7184) within `stbi__hdr_load()`:
```
while ((nleft = width - i) > 0) {
count = stbi__get8(s);
if (count > 128) {
// Run
value = stbi__get8(s);
count -= 128;
if (count > nleft) { STBI_FREE(hdr_data); STBI_FREE(scanline); return stbi__errpf("corrupt", "bad RLE data in HDR"); }
for (z = 0; z < count; ++z)
scanline[i++ * 4 + k] = value;
} else {
// Dump
if (count > nleft) { STBI_FREE(hdr_data); STBI_FREE(scanline); return stbi__errpf("corrupt", "bad RLE data in HDR"); }
for (z = 0; z < count; ++z)
scanline[i++ * 4 + k] = stbi__get8(s);
}
}
```
The proof of concept file manages to get this part of the decoder into a state
where:
* `nleft` is equal to 11;
* `s` is at the end of the file.
Because `s` is at the end of the file, `stbi__get8()` always returns 0, since
`s->img_buffer == s->img_buffer_end` here:
```
stbi_inline static stbi_uc stbi__get8(stbi__context *s)
{
if (s->img_buffer < s->img_buffer_end)
return *s->img_buffer++;
if (s->read_from_callbacks) {
stbi__refill_buffer(s);
return *s->img_buffer++;
}
return 0;
}
```
This means that `count` is always set to 0; this passes the error check, but
doesn't affect any program state, meaning that the loop runs forever, an
availability issue.
**To Reproduce**
This .zip contains a 222 KB .hdr file, rle_iloop_poc.hdr, which reproduces this issue:
[rle_iloop_poc.zip](https://github.com/nothings/stb/files/7306659/rle_iloop_poc.zip)
Calling `stbi_load()` with a path to this file never returns. I was able to
verify this using tests/image_test.c (modified slightly in order to build) on
Windows version 20H2 with Microsoft Visual Studio 2019, and I expect it should
reproduce on other systems as well.
This file was found using the [Radamsa fuzzer](https://gitlab.com/akihe/radamsa).
I think this particular file works by setting the RLE flags on the last scanline
in the file and being truncated in just the right place, but I'm not 100% sure.
**Expected behavior**
stbi_load should eventually return.
Based on Bruce Walter's
[https://www.graphics.cornell.edu/~bjw/rgbe/rgbe.c HDR reader](https://www.graphics.cornell.edu/~bjw/rgbe/rgbe.c),
it seems like the intended behavior is that a run length of 0 should be treated
as invalid, which is the approach the pull request takes. However, other
solutions are possible (e.g. detecting when the end of the file has been reached) - I don't have any preference either way.

CVE-2021-42716 | 2021-10-21T19:15:08.083 | An issue was discovered in stb stb_image.h 2.27. The PNM loader incorrectly interpreted 16-bit PGM files as 8-bit when converting to RGBA, leading to a buffer overflow when later reinterpreting the result as a 16-bit buffer. An attacker could potentially have crashed a service using stb_image, or read up to 1024 bytes of non-consecutive heap data without control over the read location. | {

] | **Summary**
stb_image's PNM loader in version v2.27 incorrectly interpreted 16-bit PGM files as 8-bit when converting to RGBA, leading to buffer overflow when later reinterpreting the result as a 16-bit buffer. An attacker could potentially have crashed a service using stb_image, or read up to 1024 bytes of non-consecutive heap data without control over the read location.
CVE number: [CVE-2021-42716](https://nvd.nist.gov/vuln/detail/CVE-2021-42716)
**Describe the bug**
In stb_image's PNM reader, loading a valid 16-bit PGM file that is large enough
with the number of components set to 4 can cause a crash in
`stbi__convert_16_to_8()` due to an out-of-bounds read.
This issue includes a fix in pull request #1223, and a proof of concept file that
can be used to reproduce the crash. We're reporting this on GitHub Issues
following the guidance in issue #1213.
This appears to be due to how when `stbi__pnm_load()` loads a 16-bit PGM file
with N bytes of data, it incorrectly calls `stbi__convert_format()` instead of
`stbi__convert_format16()`, returning a buffer that is 2N bytes long instead of
4N bytes. Since `ri.bits_per_channel` is still 16 when control returns to
`stbi__load_and_postprocess_8bit()`, `stbi__convert_16_to_8()` attempts to read
`img_len=4N` bytes of data from this buffer, resulting in out-of-bounds reads.
When N is large enough, this results in an access violation.
**To Reproduce**
This .zip contains a 513 KB .pgm file, 16_to_8_oob_poc.pgm, which reproduces this issue:
[16_to_8_oob_poc.zip](https://github.com/nothings/stb/files/7306670/16_to_8_oob_poc.zip)
Calling `stbi_load()` with a path to this file and with a req_comp of 4 produces a
crash. I was able to verify this using tests/image_test.c (modified slightly in
order to build) on Windows version 20H2 with Microsoft Visual Studio 2019, and
I expect it should reproduce on other systems as well.
This file was generated using the following Python script, and should be a valid PGM file:
```
f = open('16_to_8_oob_poc.pgm', 'wb')
f.write(b'P5\n\n512 512\n65535\n')
f.write(bytearray([1]*512*512*2))
f.close()
```
It was derived from an example found using the [Radamsa fuzzer](https://gitlab.com/akihe/radamsa).
Interestingly, tests/pbm/basi0g16.pgm is also a 16-bit PGM file, but reading it
doesn't cause a crash! I believe the reason is because this is a 32 x 32 image,
so it only includes N=2048 bytes of image data, and as a result the out-of-bounds
reads don't cross a page boundary that would result in an access violation.
**Expected behavior**
The example file should be loaded without crashing.
**Screenshots**
Here's a screenshot showing where the crash occurs and the call stack, when run
with the example file in image_test.c. (Note that the call in image_test.c may
be off by 2 lines; the specific callsite is `stbi_load(argv[i], &w, &h, &n, 4)`.)

] | I have tried a few examples and have noticed that some things occur when trying to run `wifi-config` using `mcconfig -d -m -p esp` from my MacBook Pro 2015.
1. `warning: serialport_set_baudrate: baud rate 921600 may not work` appears consistently
2. `install modules failure` shows up after sync hitting 100% sometimes
I am presuming this relates to `serialport_set_baudrate`
3. An exception seems to always occur due to some timer, that shows up even without the module failure.
```

then we need a Key Parameters called pwg_token,there are many ways to get a token
i visit http://your-url/admin.php?page=user_list
then i got pwg_token=3c28c3bf6adc56b0695cf64073605f9b
The point of vulnerability is in admin/batch_manager_global.php；The parameter selection is not filtered
Unfiltered parametersselection is spliced
The next step is to capture packets using BurpSuite by simply constructing parameters

] | **Issue Summary**
A session-fixation vulnerability exists within Pluck's administrative login system which can be abused to retain a valid login session even after an administrator has changed their password.
**Detailed Description**
It is possible to arbitrarily set the session ID of Pluck's "PHPSESSID" cookie. This cookie is used for maintaining administrative login sessions. This can be used in a session-fixation attack, for example, to sustain unauthorized access to the CMS after already gaining it through a primary vulnerability. Furthermore, Pluck does not expire sessions in a timely manner nor are sessions bound in any other way. This also allows an easier brute force attack, as it is possible to brute-force session IDs without rate-limits imposed by the normal login process.

**Reproduction Steps**
1. From Google Chrome, open the developer tools menu, navigate to: Application > Storage -> Cookies -> <PLUCK_DOMAIN>
2. Change the value of the "PHPSESSID" cookkie to an arbitrary value, such as "wolf".
3. Login to the pluck administrative panel, by visiting <PLUCK_DOMAIN>/login.php and login to the panel.
4. On a new browser, repeat steps 1 and 2.
5. On step 3, you will be given access without being prompted for administrative credentials.
**Impact**
After any primary exploit has occurred, the session fixation attack can be used in order to sustained unauthorized access. Because Pluck does not invalidate prior sessions after a password change, access can be sustained even after an administrator performs regular remediation attempts such as resetting their password. | Pluck 4.7.15 - Session Fixation Vulnerability | https://api.github.com/repos/pluck-cms/pluck/issues/99/comments | 4 | 2021-04-21T03:45:08Z | 2021-04-30T23:32:01Z | https://github.com/pluck-cms/pluck/issues/99 | 863,419,795 | 99 |

] | **Issue Summary**
Pluck's module and theme installers are vulnerable to directory traversal (via zip slip).
**Detailed Description**
It is possible to upload a malicious zip file in order to traverse directories outside of the intended environment, potentially allowing arbitrary code execution which will run with the permissions of the user assigned to the webserver.
**Reproduction Steps**
1. Using the [evilarc tool](https://github.com/ptoomey3/evilarc), create a zip archive containing a PHP file with a depth of 2 `(python evilarch.py shell.php -d 2 -f wolf.zip)`
2. Visit `<pluck_domain>/admin.php?action=themeinstall `and upload the malicious `wolf.zip` you created.
3. Visit `<pluck_domain>/shell.php` and you now have a PHP shell.
**Impact**
This vulnerability makes remote code execution under the privileges of the user running the webserver application possible. | Pluck 4.7.15 - Zip Slip Vulnerability | https://api.github.com/repos/pluck-cms/pluck/issues/100/comments | 2 | 2021-04-21T04:09:29Z | 2021-04-26T18:17:23Z | https://github.com/pluck-cms/pluck/issues/100 | 863,429,744 | 100 |

] | I uploaded any file in the "manage files" section, here I uploaded a "1.jpg".
Found two files at the upload folder.
Looked at the source code for the delete file function. On lines 21 and 22 of "data/in/deletefile.php", the logic is that the file ".htaccess" is not allowed to be deleted. But it can be bypassed.
I clicked on the delete button on the page for "1.jpg" and sniffered the packet.
Change the value of the request parameter "var" to ".Htaccess" (the suffix name is not case sensitive in Windows)
".Htaccess" is already in the trash.
The ".htaccess" in the upload folder has been copied to the trash folder.
Looked at the source code for the upload function, lines 34 to 52 of "data/in/file.php".
The code logic is as follows.
1. First check if the file suffix is ".htaccess".
2. then check if the file suffix is in the blacklist.
3. If the suffix is in the blacklist, add the suffix ".txt" for renaming and give permission.
4. If the suffix name is not in the blacklist, then give permission directly.
Use race condition for attacks.
First I create a "phpinfo.php" file.
poc:
<?php phpinfo();?>
Upload the file and sniffer a packet of the upload request and send it to intruder (add variable a=1 to keep sniffering the request packet).
Then sniffer a packet that accesses the file and send it to intruder.
Both intruder types are selected as "Numbers" and the number is 10000.
Threads are set to 20.
Start the attack, when the status of the request to access the file is 200, it means that the file was uploaded successfully and the code was executed.
Upload webshell with race condition and successfully gain access to the server.
exploit：
(Note: the ".php" file only exists when the race condition is in place, if the race condition is stopped the ".php" file will still be a ".php.txt" file, so the shell will disconnect. The shell will then disconnect. (So maintaining permissions requires that race condition be maintained at all times)

Pluck's update system deliberately skips SSL certificate validation.
**Detailed Description**
Within update_applet.php is the following code:
```
// Dont check ssl certifical
curl_setopt($geturl, CURLOPT_SSL_VERIFYPEER, false);
```
This ensures peer SSL certificates are never valdiated.
**Impact**
In theory, this vulnerability can make the Pluck's update system susceptible to Man-in-the-middle attacks. | Pluck 4.7.15 - Missing SSL Certificate Validation in update_applet.php | https://api.github.com/repos/pluck-cms/pluck/issues/101/comments | 3 | 2021-04-21T17:59:48Z | 2021-12-26T04:06:21Z | https://github.com/pluck-cms/pluck/issues/101 | 864,135,418 | 101 |

] | Description: Privilege Escalation Vulnerability due to the session validation weakness
The Profile function in CuppaCMS before 31 Jan 2021 has a privilege escalation vulnerability due to the session validation weakness. Attacker could escalate their privilege to Super Admin by tampering the HTTP Request, then to obtain full control of the CuppaCMS.
** Proof of Concept**
Step 1: Access the profile function with a low privilege account
Step 2: Add the user_group_id_field as one of the POST parameter, and set the value to "1"
Original Request
Edited Request: added the "user_group_id_field" parameter as highlighted
Response: 2 means successfully updated the record
Step 3: Re-login the account, and obtained super admin privilege

The JFinal_cms is vulnerable to regex injection that may lead to Denial of Service.
User controlled `path` and `contextPath` are used to build and run a regex expression (first argument to replaceFirst):
https://github.com/jflyfox/jfinal_cms/blob/1a9653264be5a2fcf3641ae2aa5f14fc188fd192/src/main/java/com/jflyfox/modules/filemanager/FileManager.java#L929-L949
Since the attacker controls the string and the regex pattern he may cause a ReDoS by regex catastrophic backtracking on the server side.

] | 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.
