**Name of the Vulnerable Software and Affected Versions**
Drupal versions 6.x before 6.13
**Description**
The issue allows remote authenticated users to inject arbitrary web script, HTML, and possibly PHP code via a crafted user signature, because it does not prevent users from modifying user signatures after the associated comment format has been changed to an administrator-controlled input format.
