* Advisory ID: DRUPAL-SA-CONTRIB-2010-001 * Project: Wunderbar! (third-party module) * Version: 6.x * Date: 2010-January-6 * Security risk: Not Critical * Exploitable from: Remote * Vulnerability: Cross Site Scripting -------- DESCRIPTION --------------------------------------------------------- The Wunderbar! module provides a floating bar with configurable buttons and the ability to link off to social networking sites. The module does not properly escape user names, potentially allowing a cross site scripting [1] (XSS) attack which may lead to the user gaining full administrative access. The risk is mitigated by Drupal's default configuration, which disallows some characters (<, >, &, and quotes) in user names. A site would only be vulnerable to this attack if it uses an alternate means to create usernames. -------- VERSIONS AFFECTED --------------------------------------------------- * Wunderbar! versions 6.x prior to 6.x-0.6 Drupal core is not affected. If you do not use the Wunderbar! module, there is nothing you need to do. -------- SOLUTION ------------------------------------------------------------ Install the latest version: * If you use Wunderbar! for Drupal 6.x upgrade to Wunderbar! 6.x-0.6 [2] See also the Wunderbar! project page [3]. -------- REPORTED BY --------------------------------------------------------- Isaac Sukin [4]. -------- FIXED BY ------------------------------------------------------------ Bryan Ollendyke [5], the Wunderbar! project maintainer. -------- CONTACT ------------------------------------------------------------- The security team for Drupal can be reached at security at drupal.org or via the form at http://drupal.org/contact.
