In fact when the administrator is logged in and an internal attacker will connect to web management interface (default is http://192.168.1.1:80) he will be able to see the MAC Address of logged admin. Symply changing his MAC Address the attacker can bypass authentication and login as administrator.   3)Exploit For example in OSX Snow Leopard you can on the fly change your MAC Address with the simple following CLI command:   ifconfig en0 ether <admin_mac_address> (where en0 is the name of your network interface)
