[IT-SecurityNotifies] [Security-news] SA-CONTRIB-2010-064 - Ubercart MIGS Payment Gateway - Web Parameter Tampering

[security-news AT drupal.org]

  * Advisory ID: DRUPAL-SA-CONTRIB-2010-064
  * Project: Ubercart MIGS Payment Gateway (third-party module)
  * Versions: 6.x
  * Date: 2010-Jun-16
  * Security risk: Critical
  * Exploitable from: Remote
  * Vulnerability: Web Parameter Tampering

The Ubercart MIGS Payment Gateway module provides support for the MIGS
3rd-party payment gateway used by ANZ, Commonwealth Bank, Bendigo Bank, and
various other banks worldwide for payment processing. This module was
susceptible to web parameter tampering [1] which allowed users to bypass
paying the full amount due on checkout. The amount paid was correctly
recorded against the order, but certain site configurations might allow
purchases to be delivered despite incomplete payment. This has been resolved
in the latest release, which also incorporates other features to match bank
requirements.
-------- VERSIONS AFFECTED  
---------------------------------------------------

  * Ubercart MIGS Payment Gateway for Drupal 6.x prior to uc_migs-6.x-1.2.

module, there is nothing you need to do.
