* 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 [1]) 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 [2] module, there is nothing you need to do. -------- SOLUTION ------------------------------------------------------------ Install the latest version: * If you use the Comment Edited module for Drupal 6.x upgrade to Comment Edited 6.x-1.4 [3] See also the Comment Edited project page [4]. -------- REPORTED BY --------------------------------------------------------- * Balazs Dianiska (snufkin) [5], module maintainer -------- FIXED BY ------------------------------------------------------------ * Balazs Dianiska (snufkin) [6], module maintainer -------- CONTACT AND MORE INFORMATION ---------------------------------------- The Drupal security team can be reached at security at drupal.org or via the form at http://drupal.org/contact.
