What to do

Workaround: Westermo advises users to disable HTTP access to the WebGUI and instead use HTTPS instead. This change will secure the credentials and session IDs, effectively nullifying the exploits described. To mitigate the risk of a denial-of-service attack through continuous login attempts, Westermo recommends disabling access to the device's WebGUI on external communication interfaces. For devices in production environments, disabling the WebGUI is suggested if possible. Westermo suggests limiting access to the device's CLI on external communication interfaces to prevent SSH DOS attacks through repeated login attempts. Westermo will keep users updated on any further enhancements.
