Commerce Authorize.Net SIM/DPM Payment Methods – Access Bypass – DRUPAL-SA-CONTRIB-2016-006

Leave a comment

Description

This module enables you to make credit card payments for Drupal Commerce orders via the Authorize.Net payment gateway using either their SIM (hosted payment page) or DPM (direct post method) mechanisms.

The module doesn’t sufficiently protect against the premature triggering of order completion without successful payment by the manual entry of a specially-constructed URL which contains the correct payment redirect key.

This vulnerability is mitigated by the fact that an attacker must know the format of the redirect URL and the current payment redirect key. It’s also worth noting that orders prematurely completed in this fashion will NOT record a successful payment and thus show an unpaid balance.
