[Security-news] SA-CONTRIB-2012-134 - Views - Privilege Escalation

[security-news at drupal.org]

View online: http://drupal.org/node/1762492

  * Advisory ID: DRUPAL-SA-CONTRIB-2012-134
  * Project:
    (third-party module)
  * Version: 6.x
  * Date: 2012-August-29
  * Security risk: Critical [1]
  * Exploitable from: Remote
  * Vulnerability: Privilege escalation

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

The Views module provides a flexible method for Drupal site designers to
control how lists and tables of content, users, taxonomy terms and other data
are presented.

The module incorrectly modifies the global user object in some situations
when a view has a uid argument and performs validation on that argument.

This vulnerability is mitigated by the fact that it only affects sites with
more roles than default where a role with a low role ID has more privileges
than other roles on the site and where untrusted (i.e. potentially malicious)
users are granted several of those roles.

CVE: Requested

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

  * Views 6.x-2.x versions prior to 6.x-2.16.

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 Views module for Drupal 6.x, upgrade to Views 6.x-2.16 [2]

project page.
