WPA2 KRACK Vulnerability

Released Date: 2017-10-18

When DrayTek wireless products, such as wireless routers and access points, are used as wireless base stations, they are not affected by the KRACK (Key Reinstallation AttaCK) vulnerability; therefore patches or updates are not required. However, other devices connecting to DrayTek products and functioning as wireless clients (e.g., mobile phones, tablets, laptops, and etc.,) could be vulnerable. You should check with device vendors to determine if updates are needed.

When DrayTek products are used as wireless clients and access to the Internet with universal repeater or wireless WAN modes, the wireless traffic is susceptible to interception as the router or access point is acting as a wireless client. DrayTek will be releasing firmware updates to address the issue starting next week.
