Your Telnet Backdoor is waiting for you

It is too bad if your device has a backdoor directly from the vendor. In some devices of the vendor D-Link you are able to find a nice telnet server listening on the internal network interface. The following output shows the results of a Nmap scan of three different D-Link DIR devices (DIR-300revA, DIR-300revB, DIR-600revB):
