SQL injection in signupuser.php in Code Projects Online Quiz Site 1.0 allows remote attackers to access and alter database data. The handler embeds the unauthenticated POST lid value directly in a MySQL query without cleaning, validation, or parameter binding. A time-based blind SLEEP payload reaches the registration endpoint without login and enables database enumeration, disclosure, or modification.
