Vulnerability details
The vulnerability allows a remote attacker to disclose application configuration data, internal endpoint routes, and hardcoded Brazilian national ID numbers without authentication.
The vulnerability exists due to missing authentication enforcement in WeGIA's html/atendido/Cadastro_Atendido.php when failed session or permission checks issue redirects without terminating script execution. A remote attacker can send a GET request without a session cookie and inspect the redirect response body to retrieve the complete registration page, including atendido_tipo and atendido_status table contents.
