By Drupal Security Team on
  • Advisory ID: DRUPAL-SA-CONTRIB-2010-106
  • Project: Comment Edited (third-party module)
  • Version: 6.x
  • Date: 2010-Dec-01
  • Security risk: Moderately critical
  • Exploitable from: Remote
  • Vulnerability: Cross Site Scripting

Description

The Comment Edited module displays a customizable message at the bottom of a comment when it has been edited.

The module does not sanitize some of the user-supplied data before displaying it, leading to a Cross Site Scripting (XSS) vulnerability that may lead to a malicious user gaining full administrative access.

This vulnerability is mitigated by the fact that the attacker must have a role with the 'administer comments' permission which should generally only be granted to trusted roles.

Versions affected

  • Comment Edited module for Drupal 6.x versions prior to 6.x-1.4

Drupal core is not affected. If you do not use the contributed Comment Edited module, there is nothing you need to do.

Solution

Install the latest version:
