  * Advisory ID: DRUPAL-SA-CONTRIB-2013-071
  * Project: Flag [1] (third-party module)
  * Version: 7.x
  * Date: 2013-August-28
  * Security risk: Moderately critical [2]
  * Exploitable from: Remote
  * Vulnerability: Cross Site Scripting

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

The Flag module allows creation of customizable flags on entities.

Flag does not properly sanitize the name of a flag on the main flag
administration page, allowing a malicious user to embed scripts within a
page, resulting in a Cross-site Scripting (XSS) vulnerability.

This vulnerability is mitigated by the fact that an attacker must have the
'Administer flags' permission.


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

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

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

  * Flag 7.x-3.x versions prior to 7.x-3.0.

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

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

Install the latest version:

  * If you use the Flag module for Drupal 7.x, upgrade to Flag 7.x-3.1 [5]
