CVE-2022-4403Public exploitNetwork attack vector

Authenticated SQL injection via customer_id query

Published Dec 11, 2022 · Updated Apr 15, 2025

SQL injection in ajax_represent.php in Canteen Management System allows remote authenticated users to alter database queries. The handler uses the customer_id request argument in database processing without neutralizing SQL syntax, so supplied syntax changes the executed query. A valid low-privilege session is required; successful exploitation allows unauthorized reading, modification, or deletion of application database data.
