View online: http://drupal.org/node/1916312 * Advisory ID: DRUPAL-SA-CONTRIB-2013-015 * Project: Manager Change for Organic Groups [1] (third-party module) * Version: 7.x * Date: 2013-February-13 * Security risk: Less critical [2] * Exploitable from: Remote * Vulnerability: Cross Site Scripting -------- DESCRIPTION --------------------------------------------------------- This module extends Organic Groups to allow the manager of a group to select a new manager for their group (ie if they want to leave the group). The autocomplete field for selecting a new manager didn't properly filter usernames. The vulnerability is mitigated by the fact that Drupal's default registration validation prevents the creation of username that contain cross site scripting attacks. However, a contributed module may bypass that validation or alter the way usernames are loaded in a way that introduces an attack vector. -------- CVE IDENTIFIER(S) ISSUED -------------------------------------------- * /A CVE identifier [3] will be requested, and added upon issuance, in accordance with Drupal Security Team processes./ -------- VERSIONS AFFECTED --------------------------------------------------- * Manager Change for Organic Groups 7.x-2.x versions prior to 7.x-2.1. Drupal core is not affected. If you do not use the contributed module, there is nothing you need to do. -------- SOLUTION ------------------------------------------------------------ Install the latest version: * If you use the 2.x branch of the Manager Change for Organic Groups module for Drupal 7.x, upgrade to Manager Change for Organic Groups 7.x-2.1 [4] Also see the Manager Change for Organic Groups project page. -------- REPORTED BY --------------------------------------------------------- * Michael Hess [5] of the Drupal Security Team -------- FIXED BY ------------------------------------------------------------ * Joe Haskins [6] the module maintainer -------- COORDINATED BY ------------------------------------------------------ * Michael Hess [7] of the Drupal Security Team -------- CONTACT AND MORE INFORMATION ---------------------------------------- The Drupal security team can be reached at security at drupal.org or via the contact form at http://drupal.org/contact [8].
