Remotely reboot the router of any Virgin Media Superhub customer (Major UK ISP)

Virgin Media have an online activation process for their superhub users and at the end of the process they automatically reboot your router; but once this process is completed visiting this URL reboots your router regardless with no CSRF protection.

URL: http://activation.virginmedia.com/Activation/start.do

so a simple iframe on any webpage is enough to restart any virgin superhub users connection with a 3-5 minute reboot.
