Summary

The Online Payments with iK Pay Gateway WordPress plugin before 3.0.4 does not properly verify the authenticity of its payment gateway callback on a default installation. This allows unauthenticated attackers to forge a successful payment notification and mark arbitrary orders as paid without any payment being made, and to mark arbitrary unprocessed orders as failed.

Risk Assessment

Attackers can forge payment notifications, marking orders as paid without payment, leading to financial losses and disruption of order fulfillment.

Recommendation

Update the plugin to version 3.0.4 or later, which properly verifies the authenticity of payment gateway callbacks.
