[drupal-peru] [Security-news] SA-CONTRIB-2010-043: Wordfilter - Cross Site Scripting

[securi...@drupal.org]

* Advisory ID: DRUPAL-SA-CONTRIB-2010-043
* Project: Wordfilter (third-party module)
* Version: 5.x, 6.x
* Date: 2010-May-12
* Security risk: Moderately critical
* Exploitable from: Remote
* Vulnerability: Cross Site Scripting

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

The Wordfilter module implements an input filter that rewrites content to
remove improper or foul language. Wordfilter does not sanitize the list of
words that are filtered along with their replacements, allowing users with
permissions to manage the list of banned words to insert arbitrary HTML and
script code. Such a cross site scripting [1] (XSS) attack may lead to a
malicious user gaining full administrative access. This vulnerability is
mitigated by the attacker needing the "administer words filtered" permission
in order to exploit it.
-------- VERSIONS AFFECTED
---------------------------------------------------

* Wordfilter 5.x prior to 5.x-1.1 [2]
* Wordfilter 6.x prior to 6.x-1.1 [3]

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

* If you use Wordfilter module for Drupal 5.x, update to Wordfilter 5.x-1.1
[4].
* If you use Wordfilter module for Drupal 6.x, update to Wordfilter 6.x-1.1
[5].
