Vulnerability Report

Reported:  January 3, 2012
Author: Justin C. Klein Keane <justin@madirish.net>

Description of Vulnerability:
- -----------------------------
Drupal (http://drupal.org) is a robust content management system (CMS)
written in PHP and MySQL.  The Drupal Custom Publishing Options module
(https://drupal.org/project/custom_pub) contains a persistent cross
site scripting (XSS) vulnerability due to the fact that it fails to
sanitize format names before display.

Systems affected:
- -----------------
Drupal 6.22 with Custom Publishing Options 6.x-1.4 was tested and
shown to be vulnerable

Impact
- ------
User could inject arbitrary scripts into pages affecting site users.
This could result in administrative account compromise leading to web
server process compromise.

Mitigating factors:
- -------------------
In order to execute arbitrary script injection malicious users must
have 'Administer nodes' permission.

Proof of Concept:
- -----------------
1.  Install and enable the Custom Publishing Options module
2.  Add a new label at ?q=admin/content/custom_pub inserting arbitrary
HTML in the 'Publishing label' field.
3.  Save the label to view the rendered script or view it on the
create content page for the appropriate content type.

Vendor response:
- ---------------
Upgrade to the latest version
