CVE-2022-36731Public exploitNetwork attack vector

Database disclosure via unneutralized RollNo query

Published Aug 30, 2022 · Updated Aug 3, 2024

SQL injection in kingbhob02 Library Management System 1.0 allows remote attackers to read database data through a crafted RollNo value. The /LMS/librarian/delstu.php handler incorporates the POSTed RollNo value into a database query without neutralizing SQL syntax, and an error-based updatexml payload returns the database name. The proof-of-concept request requires network access to the librarian deletion endpoint but presents no application session credential; the demonstrated consequence is database-name disclosure.
