[IT-SecNots] [Security-news] SA-CONTRIB-2011-017 - Save Draft - Validation Bypass

[security-news AT drupal.org]

  * Advisory ID: DRUPAL-SA-CONTRIB-2011-017
  * Project: Save Draft [1] (third-party module)
  * Version: 6.x, 7.x
  * Date: 2011-April-27
  * Security risk: Moderately critical [2]
  * Exploitable from: Remote
  * Vulnerability: Validation bypass

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

The Save Draft module adds a "Save as draft" button to the node form, letting
content creators easily save a post in unpublished draft form.

The module adds validation to individual form actions, thereby bypassing any
form-wide validation that is normally performed before saving content. This
is a security vulnerability for sites where other modules are using node
validation for security purposes.

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

  * Save Draft module for Drupal 6.x versions prior to 6.x-1.8
  * Save Draft module for Drupal 7.x versions prior to 7.x-1.4

Drupal core is not affected. If you do not use the contributed Save Draft [3]
module, there is nothing you need to do.

-------- SOLUTION  
------------------------------------------------------------

Install the latest version:

  * If you use the Save Draft module for Drupal 6.x, upgrade to Save Draft
    6.x-1.8 [4]. (Note that the 6.x-2.x branch of the module is not affected.
    If you use that, you do not need to upgrade.)
  * If you use the Save Draft module for Drupal 7.x, upgrade to Save Draft
    7.x-1.4 [5].

See also the Save Draft project page [6].
