[IT-SecurityNotifies] [Security-news] SA-CONTRIB-2010-101 - Watcher - Multiple Vulnerabilities

[security-news AT drupal.org]

  * Advisory ID: DRUPAL-SA-CONTRIB-2010-101
  * Project: Watcher
  * Version: 5.x, 6.x
  * Date: 2010-October-27
  * Security risk: Critical
  * Exploitable from: Remote
  * Vulnerability: Cross-site Scripting and Cross-site Request Forgery

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

The Watcher module lets users subscribe to nodes so they receive email
notifications when comments are posted or nodes are changed. The Watcher
module did not sanitize some of the user supplied data before displaying it,
leading to a Cross Site Scripting (XSS [1]) vulnerability which can be used
by a malicious user to gain full administrative access. The Watcher module
did not protect the subscribe and unsubscribe links against Cross-site
Request Forgeries (CSRF [2]).

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

  * Watcher for Drupal 5.x prior to Watcher 5.x-1.7
  * Watcher for Drupal 6.x prior to Watcher 6.x-1.4

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

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

Install the latest version:

  * If you use Watcher for Drupal 5.x upgrade to Watcher 5.x-1.7 [4]
  * If you use Watcher for Drupal 6.x upgrade to Watcher 6.x-1.4 [5]

See also the Watcher [6] project page.
