Technical details
The vulnerability is an Improper Access Control (CWE-284) within the 'make-hosted-payment' AJAX action. The plugin fails to verify if the user requesting the action has the appropriate permissions or ownership of the specified 'order_id'. An unauthenticated attacker can exploit this by sending a crafted POST request to 'admin-ajax.php' with a valid 'frontNonce' to overwrite the 'payplus_page_request_uid' metadata of any WooCommerce order. This metadata tampering can potentially be chained to bypass payment verification if the attacker provides a transaction ID from a legitimate payment they made, as the internal IPN routine does not sufficiently validate the transaction amount or ID against the specific order. The issue is resolved in version 8.2.2.
