* Advisory ID: DRUPAL-SA-CONTRIB-2009-072 * Project: RealName (third-party module) * Version: 6.x * Date: 2009-October-14 * Security risk: Moderately Critical * Exploitable from: Remote * Vulnerability: Cross Site Scripting -------- DESCRIPTION --------------------------------------------------------- The RealName module allows the administrator to choose fields from the user profile that will be used to add a "real name" element (method) to a user object. In some specific cases, the module does not sanitize before outputting the realname, resulting in a cross-site scripting (XSS [1]) vulnerability. Such an attack may lead to a malicious user gaining full administrative access. -------- VERSIONS AFFECTED --------------------------------------------------- * RealName 6.x-1.x prior to 6.x-1.3 Drupal core is not affected. If you do not use the contributed RealName module, there is nothing you need to do. -------- SOLUTION ------------------------------------------------------------ Install the latest version: * If you use the RealName for Drupal 6.x-1.x upgrade to RealName 6.x-1.3 [2] See also the RealName module project page . -------- REPORTED BY --------------------------------------------------------- mr.baileys [3] -------- FIXED BY ------------------------------------------------------------ NancyDru [4], the module maintainer -------- CONTACT ------------------------------------------------------------- The security team for Drupal can be reached at security at drupal.org or via the form at http://drupal.org/contact.
