Mitigation
Rockwell Automation mitigation
Rockwell Automation recommends upgrading to ISaGRAF Runtime 5 version 5.72.00.
Customers should ensure that the least-privilege user principle is followed, and user/service account access to Runtime’s folder location is granted with a minimum amount of rights as needed.
For ISaGRAF, restrict or block traffic on TCP 1131 from outside of the industrial control system network zone. For more information on the TCP/UDP ports used by ISaGRAF refer to product documentation.
Since ISaGRAF 5 Runtime is provided to a customer as a development kit, implementing least-privilege may vary from implementation to implementation based on the hardware in use.
For AADvance controllers, customers are encouraged to restrict or block traffic on TCP 1132 from outside of the industrial control system network zone.1
