Technical details
The signup.php registration handler concatenates user-supplied POST parameters (particularly fname) directly into a SQL INSERT statement without sanitization or prepared statements, enabling error-based SQL injection. An attacker can craft a malicious registration request to both disclose the raw SQL query via error messages and extract arbitrary database data by injecting subqueries into the Values clause. The vulnerability requires no authentication and is remotely exploitable via HTTP POST requests.
