* Advisory ID: DRUPAL-SA-CONTRIB-2014-106 * Project: Commerce Authorize.Net SIM/DPM Payment Methods [1] (third-party module) * Version: 7.x * Date: 2014-October-29 * Security risk: 12/25 ( Moderately Critical) AC:Complex/A:None/CI:None/II:Some/E:Theoretical/TD:All [2] * Vulnerability: Access bypass

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

This module provides payment methods for the Drupal Commerce [3] package to permit the use of the Authorize.Net payment gateway's SIM and DPM payment protocols.

.... Access Bypass

The module doesn't sufficiently protect the Drupal Commerce order number passed to the Authorize.Net payment gateway, allowing a specially modified payment POST transaction to Authorize.Net to be applied to a previous order still in the checkout state. This could allow the previous transaction to be marked as paid despite the fact that the payment applied was smaller than its outstanding balance.

-------- CVE IDENTIFIER(S) ISSUED --------------------------------------------

* /A CVE identifier [4] will be requested, and added upon issuance, in accordance with Drupal Security Team processes./

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

* Commerce Authorize.Net SIM/DPM Payment Methods 7.x-1.x versions prior to 7.x-1.1.
