- MitigationFirmware <v2.6 installed on SIMA² Master Station
In case you cannot upgrade your SIMA² Master Station to software Version 2.6 or above, it is recommended to configure the use of internal DNS servers only and block external DNS traffic where possible. It is also recommended to segment networks and shield affected devices from untrusted networks, e.g., using firewalls. Network intrusion detection mechanisms can be used to filter malicious packets.
- FixedFirmware <v2.6 installed on SIMA² Master Station
The described vulnerabilities have been fixed in the SIMA² Master Stations with software version V 2.6 or higher. SIMA² Master Stations with software versions < V 2.6 can be upgraded. AUMA recommends applying a product update at the earliest convenience.
