[IT-SecNots] [Security-news] SA-CONTRIB-2011-042 Views Bulk Operations - Cross Site Scripting

[security-news AT drupal.org]

  * Advisory ID: DRUPAL-SA-CONTRIB-2011-042
  * Project: Views Bulk Operations (VBO) [1] (third-party module)
  * Version: 6.x
  * Date: 2011-September-21
  * Security risk: Moderately critical [2]
  * Exploitable from: Remote
  * Vulnerability: Cross Site Scripting

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

The Views Bulk Operations (VBO) module allows actions and rules to be run on
the selected views rows (nodes, terms, user, etc). It also bundles several
convenient actions. One of those actions allows the bulk modification of
taxonomy terms on a node.

When using the "Modify node taxonomy terms" action to modify taxonomy, and
the vocabulary has user tagging enabled, the vocabulary help (if any) is
shown without being filtered first, leading to a cross site scripting
vulnerability.

This vulnerability is mitigated by the fact that it normally requires the
'administer taxonomy' permission in order to exploit it.

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

Versions prior to 6.x-1.11

Operations (VBO) [3] module, there is nothing you need to do.
