The MasterStudy LMS WordPress Plugin – for Online Courses and Education plugin for WordPress is vulnerable to union based SQL Injection via the 'user' parameter of the /lms/stm-lms/order/items REST route in all versions up to, and including, 3.2.5 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

→Monitor for unauthenticated HTTP requests to the REST endpoint /lms/stm-lms/order/items with a 'user' parameter containing SQL UNION payloads. ↗
→Flag responses to /lms/stm-lms/order/items that return JSON bodies containing all three keys: 'items', 'total', and 'total_price' with HTTP 200, as this pattern is used to confirm successful SQL injection data exfiltration.
→No authentication is required to exploit this vulnerability; treat any external source querying this REST route as potentially malicious. ↗

·All MasterStudy LMS plugin versions up to and including 3.2.5 are vulnerable; ensure detections target sites running these versions. ↗
