Description

esup-helpdesk uses the Apache MyFaces extensions provided by the Tomahawk library.

Version 1.1.5 of this library, used by all the esup-helpdesk v3 distributions, has an important security hole that allows the injection of arbitrary Javascript code.

Cross Site Scripting attacks include the steal of session identifiers, thus authorizating identity theft, they are detailed on the web site of iDefense Labs.

Solution

esup-helpdesk 3.20.0 embeds version Tomahawk 1.1.6, which fixes the vulnerability (see TOMAHAWK-983).

Upgrading to esup-helpdesk 3.20.0 or later as soon as possible is strongly recommended.
