DESCRIPTION:
A weakness has been reported in D-Link DIR-685 Xtreme N Storage
Router, which can be exploited by malicious people to bypass certain
security restrictions.

The weakness is caused due to an error in the router when configured
with WPA/WPA2 and an AES pre-shared key (PSK) cipher. This can lead
to the router failing to an unencrypted connection under certain
circumstances.

SOLUTION:
Do not use an AES pre-shared key (PSK) cipher.
