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
archive
Open

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:

POST

Find database credentials
