Original Release date: 10 Oct 2011 | Last revised: 10 Oct 2011

Overview

The D-Link DIR-685 Xtreme N storage router is reported to fail open to an unencrypted wireless connection during heavy network load.

Description

The D-Link DIR-685 Xtreme N storage router when configured with WPA/WPA2 and an AES cipher with a pre-shared key (PSK) will fail to an open unencrypted wireless connection during heavy network load, such as, the transfer of several gigabytes of data. The router's wireless connection will remain in an open unencrypted state until the device is rebooted.

Impact

An attacker within physical range of the wireless router may be able to connect to the router's network without having to authenticate and then sniff traffic and also use the victim's Internet connection to launch other attacks.

Solution

We are currently unaware of a practical solution to this problem.
