[IT-SecNots] [Security-news] SA-CONTRIB-2011-056 - Webform Validation Cross Site Scripting

[security-news AT drupal.org]

  * Advisory ID: DRUPAL-SA-CONTRIB-2011-056
  * Project: Webform Validation [1] (third-party module)
  * Version: 6.x, 7.x
  * Date: 2011-November-30
  * Security risk: Moderately critical [2]
  * Exploitable from: Remote
  * Vulnerability: Cross Site Scripting

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

The Webform Validation module enables you to add form validation rules to
Webform components through a UI.

The module contains multiple cross site scripting (XSS) vulnerabilities due
to the fact that it fails to sanitize certain user entered text prior to
displaying in the browser.

This vulnerability is mitigated by the fact that an attacker must have a role
with permission to update Webform nodes. Various permissions provide for this
ability.

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

  * Webform Validation 6.x-1.x versions prior to 6.x-1.4.
  * Webform Validation 7.x-1.x versions prior to 7.x-1.0.

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

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

Install the latest version:

  * If you use the Webform Validation module for Drupal 6.x, upgrade to
    Webform Validation 6.x-1.5 [4]
  * If you use the Webform Validation module for Drupal 7.x, upgrade to
    Webform Validation 7.x-1.1 [5]
