* Advisory ID: DRUPAL-SA-CONTRIB-2010-060 * Project: Scheduler (third-party module) * Version: 5.x, 6.x * Date: 2010-May-26 * Security risk: Moderately critical * Exploitable from: Remote * Vulnerability: Cross Site Scripting -------- DESCRIPTION --------------------------------------------------------- Scheduler allows nodes to be published and unpublished on specified dates. Scheduler does not sanitize titles for unpublished nodes on the scheduled nodes overview list, leading to a Cross Site Scripting (XSS [1]) vulnerability that may lead to a malicious user gaining full administrative access. The risk is mitigated by the fact that an attacker must succeed in a) creating a node that is b) scheduled (requires "schedule (un)publishing of nodes" permission) and c) unpublished. -------- VERSIONS AFFECTED --------------------------------------------------- * Scheduler module for Drupal 5.x versions prior to 5.x-1-19 * Scheduler module for Drupal 6.x versions prior to 6.x-1.7 Drupal core is not affected. If you do not use the contributed Scheduler [2] module, there is nothing you need to do. -------- SOLUTION ------------------------------------------------------------ Install the latest version: * If you use the Scheduler module for Drupal 5.x upgrade to Scheduler 5.x-1-19 [3] * If you use the Scheduler module for Drupal 6.x upgrade to Scheduler 6.x-1.7 [4] See also the Scheduler project page [5]. -------- REPORTED BY --------------------------------------------------------- * mr.baileys [6] of the Drupal security team -------- FIXED BY ------------------------------------------------------------ * Eric Schaefer [7], module maintainer -------- CONTACT ------------------------------------------------------------- The Drupal security team [8] can be reached at security at drupal.org or via the form at http://drupal.org/contact.
