Response delays via injected user-deletion identifier
Published Nov 13, 2024 · Updated Mar 13, 2025
SQL injection in Computer Laboratory Management System 1.0 allows remote authenticated users to delay responses through a user-deletion request. The delete_users handler in classes/Users.php embeds the POST id value in a database operation without neutralizing SQL syntax, allowing a nested SLEEP query to control response time. A valid PHP session is required, and the demonstrated consequence is a 20-second response delay rather than data disclosure or modification.
