* Advisory ID: DRUPAL-SA-CONTRIB-2012-021 * Project: Organic Groups Vocabulary [1] (third-party module) * Version: 6.x * Date: 2012-February-15 * Security risk: Moderately critical [2] * Exploitable from: Remote * Vulnerability: Access bypass

-------- DESCRIPTION ---------------------------------------------------------

This module enables you to have a specific vocabulary per organic group. The module doesn't sufficiently check access to vocabularies while allowing a group admin to edit the vocabularies. This vulnerability is mitigated by the fact that an attacker must have a role with the permission to "administer own group vocabulary" and be an admin of another group.

-------- VERSIONS AFFECTED ---------------------------------------------------

* OG Vocab 6.x-1.x versions prior to 6.x-1.2.

Drupal core is not affected. If you do not use the contributed OG Vocabulary [3] module, there is nothing you need to do.

-------- SOLUTION ------------------------------------------------------------

Install the latest version:

* If you use the OG Vocab module for Drupal 6.x, upgrade to OG Vocab 6.x-1.2 [4]

See also the OG Vocabulary [5] project page.

* Chris Czeyka [6]

-------- FIXED BY ------------------------------------------------------------

* Amitai Burstein [7] the module maintainer

-------- COORDINATED BY ------------------------------------------------------
