* 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.
