Asaas Gateway for WooCommerce < 2.7.8 - Unauthenticated Arbitrary Order Status Manipulation
The Asaas Gateway for WooCommerce plugin for WordPress is vulnerable to Authentication Bypass in all versions up to 2.7.8. This is due to missing enforcement of a non-empty access token in the webhook token validator (an empty configured token matched any empty request token) and the absence of server-side verification that the Asaas-confirmed payment corresponds to the order being completed. This makes it possible for unauthenticated attackers to mark arbitrary WooCommerce orders as paid without authentication, by sending a webhook request with an empty access token and a payment ID that does not correspond to the targeted order.
