[Security-news] SA-CONTRIB-2011-002 - Panels - Cross Site Scripting (XSS)

[security-news at drupal.org]

  * Advisory ID: DRUPAL-SA-CONTRIB-2011-002
  * Project: Panels (third-party module)
  * Version: 6.x
  * Date: 2011-January-12
  * Security risk: Moderately critical
  * Exploitable from: Remote
  * Vulnerability: Cross Site Scripting

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

The Panels module allows a site administrator to create customized layouts
for multiple uses. The module does not sanitize some of the user-supplied
data before displaying it, leading to a Cross Site Scripting (XSS [1])
vulnerability that may lead to a malicious user gaining full administrative
access. This vulnerability is mitigated by the fact that the attacker must
have a role with the 'administer advanced pane settings' permission in
addition to at least one permission allowing them to create or edit panels,
such as 'use page manager', 'administer mini panels', 'create panel nodes'
etc.
-------- VERSIONS AFFECTED  
---------------------------------------------------

  * Panels module for Drupal 6.x versions prior to 6.x-3.9

Drupal core is not affected. If you do not use the contributed Panels [2]
module, there is nothing you need to do.
-------- SOLUTION  
------------------------------------------------------------

Install the latest version:
  * If you use the Panels module for Drupal 6.x upgrade to Panels 6.x-3.9 [3]

See also the Panels project page [4].
