  * Advisory ID: DRUPAL-SA-CONTRIB-2013-023
  * Project: Varnish HTTP Accelerator Integration [1] (third-party module)
  * Version: 6.x, 7.x
  * Date: 2013-February-20
  * Security risk: Less critical [2]
  * Exploitable from: Remote
  * Vulnerability: Cross Site Scripting

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

This module provides integration between your Drupal site and the Varnish
HTTP Accelerator, an advanced and very fast reverse-proxy system.

The module doesn't sufficiently filter user-supplied text provided in the
configuration settings.

This vulnerability is mitigated by the fact that an attacker must have a role
with the permission "Administer Varnish".


-------- CVE IDENTIFIER(S) ISSUED  
--------------------------------------------

  * /A CVE identifier [3] will be requested, and added upon issuance, in
    accordance with Drupal Security Team processes./

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

  * Varnish 6.x-1.x versions prior to 6.x-1.2.
  * Varnish 7.x-1.x versions prior to 7.x-1.2.

Drupal core is not affected. If you do not use the contributed Varnish HTTP
Accelerator Integration [4] module, there is nothing you need to do.

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

  * If you use the Varnish module for Drupal 6.x, upgrade to Varnish 6.x-1.2
    [5]

    7.x-1.0-beta2 [6]
