Moodle Forum 'post.php' Unauthorized Post Deletion CSRF

medium Nessus Plugin ID 35749

Language:

Synopsis

The remote web server contains a PHP application that is affected by a cross-site request forgery vulnerability.

Description

The 'forum' code in the version of Moodle installed on the remote host is affected by a cross-site request forgery vulnerability due to a failure to properly validate requests before deleting forum posts. If an attacker can trick a Moodle user into clicking on a malicious link, this issue could be leveraged to delete the user's posts.

Note that this install is also likely affected by several other vulnerabilities, including one allowing for arbitrary code execution, although Nessus has not checked for them.

Solution

Upgrade to Moodle version 1.9.4 / 1.8.8 / 1.7.7 or later.
