| Detailed Description |
The Moodle software is vulnerable to a Cross-Site Scripting Vulnerability via the file variable in the 'help.php' script.
Moodle is an open-source PHP-based course management system (CMS) for Microsoft Windows, Unix, and Linux-based platforms. The versions prior to 1.3.3 of Moodle are vulnerable a Cross-Site Scripting Vulnerability in the 'help.php' script, caused by a failure of the application to properly sanitize user-supplied input prior to including it in dynamic web content. A remote attacker could create a specially crafted URL link as the following, and then persuade a target user to click it.
http://[target_server]/help.php?file=<script>alert(document.cookie);</script>
Once the URL is clicked, the embedded codes would be executed in the victim's Web browser. A remote attacker could use this vulnerability to steal the victim's cookie-based authentication credentials.
