A SQL injection vulnerability has been identified in Zen Cart versions prior to 2.2.2. The issue resides in the PayPal IPN Handler component, specifically within the 'ipn_main_handler.php' file. The vulnerability is triggered by manipulating the 'txn_id' POST parameter, which is directly concatenated into a SQL 'UPDATE' statement's 'WHERE' clause without proper sanitization or parameterization. This flaw allows for unauthorized SQL commands to be executed, potentially leading to unauthorized data access or modification.
Users are advised to update to Zen Cart version 2.2.2 or later, where this vulnerability has been patched. The specific commit containing the fix can be found in the Zen Cart GitHub repository.
