Moodle SpellChecker Path Authenticated Remote Command Execution

Posted on 12 October 2021

Moodle allows an authenticated administrator to define spellcheck settings via the web interface. An administrator can update the aspell path to include a command injection. This is extremely similar to CVE-2013-3630, just using a different variable. This Metasploit module was tested against Moodle versions 3.11.2, 3.10.0, and 3.8.0.
