Authenticated SQL injection via concatenated user ID
Published Mar 31, 2026 · Updated Mar 31, 2026
SQL injection in Code Projects Student Membership System 1.0 allows remote authenticated users to alter or delete database records. The deletion handler in delete_user.php concatenates the POST id value directly into a mysql_query DELETE statement, allowing SQL syntax to change the query. Access to the administrative deletion function is required; exploitation can remove every administrator account or other records selected by injected SQL.
