What to do
Workaround: An attacker must have already established network access to exploit this vulnerability. WatchGuard recommends using Windows Firewall rules to restrict TCP port 4114 network access to the Authentication Gateway to only allow connections from the Firebox. Windows administrators can use Group Policy objects to add Windows firewall rules to their endpoints.
Exploitation: WatchGuard is not aware of any exploitation of this vulnerability in the wild.
