* Advisory ID: DRUPAL-SA-CONTRIB-2010-096 * Project: Domain access (third-party module) * Version: 5.x, 6.x, 7.x * Date: 2010-September-22 * Security risk: Less critical * Exploitable from: Remote * Vulnerability: Cross-Site Scripting, Priviledge Escalation -------- DESCRIPTION --------------------------------------------------------- The Domain Access module suite allows users to maintain content shared across multiple domains running from a single Drupal installation. In several instances, the module does not sanitize the user-supplied domain name 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 user must have the "administer domains" permission in order to create and edit domain names. The Domain Configuration sub-module allows certain site information settings to be configured per domain. Users with the "administer domains" permission could change these settings, even if they lacked the permission to edit the settings on the primary domain. -------- VERSIONS AFFECTED --------------------------------------------------- * Domain access module for Drupal 5.x versions prior to 5.x-1.15 * Domain access module for Drupal 6.x versions prior to 6.x.2.6 * Domain access module for Drupal 7.x versions prior to 7.x.2.4 Drupal core is not affected. If you do not use the contributed Domain access [2] module, there is nothing you need to do. -------- SOLUTION ------------------------------------------------------------ Install the latest version: * If you use the Domain access module for Drupal 5.x upgrade to Domain access 5.x-1.15 [3] * If you use the Domain access module for Drupal 6.x upgrade to Domain access 6.x.2.6 [4] * If you use the Domain access module for Drupal 7.x upgrade to Domain access 7.x.2.4 [5] See also the Domain access project page [6]. -------- REPORTED BY --------------------------------------------------------- * Sam Oldak [7] (Cross-Site Scripting) * brt [8] (Privilege escalation) * Nirbhasa Magee [9] (Privilege escalation) -------- FIXED BY ------------------------------------------------------------ * Sam Oldak [10] * Ken Rickard [11], the module maintainer -------- CONTACT ------------------------------------------------------------- The Drupal security team [12] can be reached at security at drupal.org or via the form at http://drupal.org/contact.
