CardGate Payments plugin for WooCommerce does not validate request origin
CVE-2020-8819 · GHSA-5pq5-9phv-q5j3
- Affected
- Packagist cardgate/woocommerce <= 3.1.15
- Fixed in
- 3.1.16· Vendor fix available
- Issue
- 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.
Recommended action: Upgrade to 3.1.16 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
