|---|
| Description | The public admin registration page `admin/signup.php` builds the duplicate-email check `select * from admin where email='$email'` (`admin/signup.php:18`) from raw unauthenticated input, and then inserts `$username`, `$email` and `$location` raw into the `admin` table (`admin/signup.php:28`). The two branches ("Account already exists" versus the failed insert alert) form a boolean oracle that lets an anonymous attacker query any database value bit by bit. Because the injected table is `admin` and the connection uses the MySQL `root` superuser (CVE-17), the flaw also couples directly with CVE-09: the public page lets an attacker mint a privileged administrator account with attacker-controlled columns. |
