[Security-news] SA-CONTRIB-2010-013 - Menu Breadcrumb - Cross site scripting

[security-news at drupal.org]

  * Advisory ID: DRUPAL-SA-CONTRIB-2010-013
  * Project: Menu Breadcrumb (third-party module)
  * Version: 6.x
  * Date: 2010-February-03
  * Security risk: Less critical
  * Exploitable from: Remote
  * Vulnerability: Cross Site Scripting

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

The Menu Breadcrumb module allows to use the menu the current page belongs to
as breadcrumb. The module does not properly sanitize parts of the provided
block, leading to a cross-site scripting (XSS [1]) vulnerability. Such an
attack may lead to a malicious user gaining full administrative access.
Mitigating factors: A user must have a role with the permission /administer
blocks/ to exploit this vulnerability.
-------- VERSIONS AFFECTED  
---------------------------------------------------

  * Menu Breadcrumb for Drupal 6.x prior to 6.x-1.3

Drupal core is not affected. If you do not use the contributed Menu
Breadcrumb module, there is nothing you need to do.
-------- SOLUTION  
------------------------------------------------------------

Upgrade to the latest version:
  * If you use Menu Breadcrumb for Drupal 6.x upgrade to Menu Breadcrumb
    6.x-1.3 [2]

See also the Menu Breadcrumb project page [3].
