[Security-news] SA-CONTRIB-2010-106 - Comment Edited - Cross Site Scripting

[security-news at drupal.org]

  * Advisory ID: DRUPAL-SA-CONTRIB-2010-106
  * Project: Comment Edited (third-party module)
  * Version: 6.x
  * Date: 2010-Dec-01
  * Security risk: Moderately critical
  * Exploitable from: Remote
  * Vulnerability: Cross Site Scripting

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

The Comment Edited module displays a customizable message at the bottom of a
comment when it has been edited. 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 comments' permission which
should generally only be granted to trusted roles.
-------- VERSIONS AFFECTED  
---------------------------------------------------

  * Comment Edited module for Drupal 6.x versions prior to 6.x-1.4

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

Install the latest version:
  * If you use the Comment Edited module for Drupal 6.x upgrade to Comment
    Edited 6.x-1.4 [3]

See also the Comment Edited project page [4].
