[Security-news] SA-CONTRIB-2012-021 - Organic Groups Vocab Access Bypass

[security-news at drupal.org]

  * 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.
