  * Advisory ID: DRUPAL-SA-CONTRIB-2012-119
  * Project: Excluded Users [1] (third-party module)
  * Version: 6.x
  * Date: 2012-August-1
  * Security risk: Less critical [2]
  * Exploitable from: Remote
  * Vulnerability: Cross Site Scripting

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

Excluded Users is a helper module which allows administrators to select users
to not appear in user listings.

The module displays a list of user names and email addresses without
sanitizing them. In the event that someone manages to insert malicious code
into a user name or email address, this might lead to an XSS attack.

This vulnerability is mitigated by the fact that the user name and email
address are validated on creation by default but other user creation methods
could create a vulnerability.

CVE: Requested

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

  * Excluded Users 6.x-1.x versions prior to 6.x-1.1.

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

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

    Users 6.x-1.1 [4]
