How to fix
Implement prepared statements with parameter binding (use :username and :password placeholders with execute() binding) instead of string interpolation; remove use of $_REQUEST for credentials and explicitly read from $_POST; store passwords as salted hashes and verify privileges server-side without trusting row content alone.
Technical details
A SQL injection vulnerability exists in login/index.php where user input from $_REQUEST is directly interpolated into a SQL query string before PDO::prepare() is called, negating parameterization. An unauthenticated attacker can inject UNION SELECT or tautology payloads to bypass authentication (e.g., ' OR '1'='1' -- -) and fully control session variables including usertype_id and firstname, achieving admin session hijacking. The application also stores passwords in plaintext and fails to verify privileges server-side.
