Executive brief
ProjectWorlds Online Time Table Generator is a web application used by schools and universities to automatically schedule classes. The application's admin pages fail to verify user identity, allowing anyone on the network to directly access pages listing student and teacher accounts with plaintext passwords visible. An attacker can easily extract credentials and account information without logging in, leading to unauthorized account access and potential compromise of student and teacher accounts across the institution.
Technical details
The vulnerability is a missing authentication and authorization check (CWE-306, CWE-862) in the admin pages /admin/student.php and /admin/teacher.php. These endpoints include only the database configuration file and fail to validate any session or user credentials before serving sensitive data. An unauthenticated remote attacker can directly access these endpoints via HTTP GET requests without any prior login or session token. The pages render HTML tables containing password columns for all student and teacher accounts; because the shipped default database stores passwords in plaintext, the attacker immediately gains valid credentials. The fix requires adding session validation (session_start() and $_SESSION checks) at the start of all admin pages and removing password fields from rendered output.
