Vulnerability Overview

An issue was discovered in the CardGate Payments plugin through 3.1.15 for WooCommerce. Lack of origin authentication in the IPN callback processing function in cardgate/cardgate.php allows an attacker to remotely replace critical plugin settings (merchant ID, secret key, etc.) and therefore bypass the payment process (e.g., spoof an order status by manually sending an IPN callback request with a valid signature but without real payment) and/or receive all of the subsequent payments.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity.

CWE-346: Origin Validation Error

The product does not properly verify that the source of data or communication is valid.

Remediation

Update to version 3.1.16, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: CardGate Payments for WooCommerce 3.1.16 closes this, and updating the plugin is the step that ends it.
