The problem is remediated as of the following product version SDM600 version 1.2 FP2 HF6 (Build Nr. 1.2.14002.257). Hitachi ABB Power Grids recommends that customers apply the update at the earliest convenience. After successful upgrade it is recommended to move previously created vulnerable backups to secure place to avoid any nonauthorized access.

It is recommended to implement and continuously revise least privileges principles to minimize permissions and accesses to SDM600 related resources. Furthermore, recommended security practices as defined in SDM600 security deployment guideline and firewall configurations can help to protect a process control network from attacks that originate from outside the network. Such practices include that process control systems are physically protected from direct access by unauthorized personnel, have no direct connections to the Internet, and are separated from other networks by means of a firewall system that has a minimal number of ports exposed, and others that have to be evaluated case by case. Process control systems should not be used for Internet surfing, instant messaging, or receiving e-mails. Portable computers and removable storage media should be carefully scanned for viruses before they are connected to a control system. Additional recommendation is to follow the hardening guidelines published by “The Center for Internet Security (CIS)” https://www.cisecurity.org/about-us/ to protect the host Operating System.
