[Security-news] SA-CONTRIB-2009-107 - Ubercart - Access bypass, Cross site request forgery

[security-news at drupal.org]

  * Advisory ID: DRUPAL-SA-CONTRIB-2009-107
  * Project: Ubercart (third-party module)
  * Version: 5.x, 6.x
  * Date: 2009-November-18
  * Security risk: Moderately critical
  * Exploitable from: Remote
  * Vulnerability: Access bypass, Cross-site request forgery

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

Ubercart's PayPal Website Payments Standard integration exposes a path for
completed orders without properly checking that the order is valid for the
current user. In the event that the order has already been processed for
checkout, this can result in duplicate actions taking place inadvertently.
Furthermore, if the checkout completion message has been modified to include
order details, information disclosure can happen. The Ubercart order
management was also affected by a minor cross-site request forgery
vulnerability.

  * Ubercart module for Drupal 6.x prior to Ubercart 6.x-2.1 [1]
