[IT-SecNots] [Security-news] SA-CONTRIB-2011-006 - Flag Page - Cross Site Scripting (XSS)

[security-news AT drupal.org]

  * Advisory ID: DRUPAL-SA-CONTRIB-2011-006
  * Project: Flag page (third-party module)
  * Version: 6.x
  * Date: 2011-February-02
  * Security risk: Moderately Critical
  * Exploitable from: Remote
  * Vulnerability: Cross Site Scripting

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

The contributed flag page module provides an additional flag type to allow
you to flag pages so you can bookmark any URL on your site including views,
panels, administration pages or site contact page. The module does not
sanitize the flag titles when displayed in blocks, leading to a Cross-Site
Scripting (XSS [1]) vulnerability that may lead to a malicious user gaining
full administrative access. This vulnerability is mitigated by the fact that
the user must have the "administer flags" permission in order to create and
edit flags and enter the XSS.

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

  * Flag page module 6.x-2.x versions prior to 6.x-2.2
  * Flag page module 6.x-1.x versions prior to 6.x-1.3

Note: If you do not use the contributed flag_page [2] module, there is
nothing you need to do.

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

  * If you use the Flag page module for Drupal 6.x-2.x upgrade to Flag Page
    6.x-2.2 [3]
  * If you use the Flag page module for Drupal 6.x-1.x upgrade to Flag Page
