[Security-news] SA-CONTRIB-2009-088 - Workflow Multiple Cross Site Scripting Vulnerabilities

[security-news at drupal.org]

  * Advisory ID: DRUPAL-SA-CONTRIB-2009-088
  * Project: Workflow (third-party module)
  * Version: 6.x, 5.x
  * Date: 2009-October-28
  * Security risk: Moderately Critical
  * Exploitable from: Remote
  * Vulnerability: Cross Site Scripting

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

The Workflow module enables sites to define flexible process management
systems. Names of workflows and workflow states are not sanitised to display
as plain text, leading to a Cross Site Scripting (XSS [1]) vulnerability.
Exploiting this vulnerability would allow a malicious user to gain full
administrative access. Mitigating factors: A malicious user would need
'administer workflow' permission to carry out the cross-site-scripting
attack.
-------- VERSIONS AFFECTED  
---------------------------------------------------

  * Workflow module versions Drupal 6.x prior to Workflow 6.x-1.2 [2]
  * Workflow module versions Drupal 5.x prior to Workflow 5.x-2.4 [3]

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

Install the latest version.
  * If you use the Workflow module for Drupal 6.x upgrade to Workflow 6.x-1.2
    [5]
  * If you use the Workflow module for Drupal 5.x upgrade to Workflow 5.x-2.4
