[Security-news] SA-CONTRIB-2009-091 - Node Hierarchy - Cross Site Scripting

[security-news at drupal.org]

  * Advisory ID: DRUPAL-SA-CONTRIB-2009-091
  * Project: Node Hierarchy (third-party module)
  * Version: 6.x, 5.x
  * Date: 2009 November 4
  * Security risk: Less critical
  * Exploitable from: Remote
  * Vulnerability: Cross Site Scripting

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

The Node Hierarchy module enables a site administrator to arrange their site
into a tree-like structure. When displaying the list of children for a node
the module does not properly sanitize the titles of the child nodes before
outputting them, leading to a cross-site scripting [1] (XSS) vulnerability
which would allow a user with the ability to edit the nodes to gain full
administrative access.
-------- VERSIONS AFFECTED  
---------------------------------------------------

  * Node Hierarchy versions for Drupal 6.x prior to 6.x-1.3
  * Node Hierarchy versions for Drupal 5.x prior to 5.x-1.3

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

Upgrade to the latest version:
  * If you use Node Hierarchy for Drupal 6.x upgrade to version 6.x-1.3 [2]
  * If you use Node Hierarchy for Drupal 5.x upgrade to version 5.x-1.3 [3]

See also the Node Hierarchy [4] project page.
