Synopsis

Moodle < 3.9.15 / 3.11.x < 3.11.8 / 4.0.x < 4.0.2 LTI Module Cross-Site-Scripting

Description

Moodle is a free and open-source learning management system written in PHP. Moodle versions before 3.9.15, 3.11.x before 3.11.8 and 4.0.x before 4.0.2 suffer from a Cross-Site Scripting (XSS) vulnerability through the LTI module which only affects unauthenticated users. By crafting a specific HTTP request, an attacker could leverage this vulnerability to execute malicious JavaScript in the context of unauthenticated users browsers.

Solution

Upgrade to Moodle version 3.9.15, 3.11.8, 4.0.2 or later.
