Certain models of D-Link wireless routers contain hidden functionality. By sending specific packets to the web service, the attacker can forcibly enable the telnet service and log in using hard-coded credentials. The telnet service enabled through this method can only be accessed from within the same local network as the device.
The product contains functionality that is not documented, not part of the specification, and not accessible through an interface or command sequence that is obvious to the product’s users or administrators.
