KRACKs WPA2 Vulnerability
« on: October 20, 2017, 08:50:12 am »
In WPA2, the wireless LAN encryption technology, there was an announcement that there is a vulnerability called "KRACKs".

Since this is a vulnerability depending on the implementation of the "slave" function of the WPA 2 standard, there is a possible vulnerability when using wireless client / bridge product and wireless routers which have relay functions (WB · WDS, etc.) supporting WPA 2.

We are currently conducting investigations of our products, we will publish information concerning which products are impacted and countermeasures when available.

Please note that if you are not using relay functions (WB · WDS, etc.) with the wireless router, there is no vulnerability, so please use with confidence.


Products without KRACKs issues

 WXR-1900 series
 WXR-190X series
 WXR-1750 series
 WXR-175X series
 WSR-300HP series
 WAPM series
 WAPS series

As soon as vulnerable products are identified we will release a firmware update that will eliminate the vulnerability of the applicable product.
Please update the firmware as soon as it is released.

If you are not using the wireless router in bridge mode (WB · WDS etc.), it will not be affected.
Please check the following to confirm whether bridge mode is in use. (The confirmation method differs depending on the product, so please refer each product’s manual on bridge mode.)


If you set the unit rear switch to "AUTO" during product setup, bridge mode is not enabled.
If you set the unit rear switch to "MANUAL" during product setup and "ROUTER" or "AP" is selected on the switch, bridge mode is not enabled.
If you set the unit rear switch to "MANUAL" during product setup and "WB" is selected on the switch, bridge mode is enabled.

Confirmed Unaffected Products

Current Products

Wireless Router   
WXR-1900DHP Series and WSR-300HP Series: These products can be used safely even in bridge mode. While bridge mode is enabled, the unit rear switch will be set to "WB".
      
Wireless Access Point
