There is a separate web page with more information about this attack:
On this page we collect information from our vendors so that you can react accordingly and provide information to affected customers.
The Stellar AP’s are affected from the CVE-2020-24588 (medium) and the Wifi 5 AP’s additionally from the CVE-2020-26146 (medium).
Our team is working on the patch (will take a few more weeks to patch).
As a best practice, we continue to actively recommend Rogue AP Detection/Protection (WIDS/WIPS) to more strongly counter the Man in the Middle attack until the patch is available.
Additionally, using the new authentication standards WPA3 (with PMF) as well as certificate-based authentication will help.
Watchguard will provide updates for the following products:
- Firebox with build-in WLAN
- APs managed by a Firebox (Gateway Wireless Controller)
- APs managed by the Wi-Fi Cloud
As soon as the above updates are ready, Watchguard will inform customers and partners.
