Hitachi ABB Power Grids reported this vulnerability to CISA.
Hitachi ABB Power Grids recommends users apply update Version 1.2 FP2 HF6 (Build Nr. 1.2.14002.257) or newer at the earliest convenience. Users can download the latest SDM600 version from the product website. After successful upgrade, Hitachi ABB Power Grids recommends moving previously created vulnerable backups to a secure location to avoid unauthorized access.
Hitachi ABB Power Grids also recommends the following general security mitigations:
- Implement and continuously revise least privileges principles to minimize permissions and accesses to SDM600 related resources.
- Follow security practices as defined in SDM600 security deployment guideline and firewall configurations to help protect process control networks from attacks that originate from outside the network. Such practices include that process control systems are:
- Physically protected from direct access by unauthorized personnel.
- Not directly connected to the Internet.
- Separated from other networks by means of a firewall system that has a minimal number of ports exposed.
- Not used for Internet surfing, instant messaging, or receiving e-mails.
- Carefully scan portable computers and removable storage media for viruses before connecting to a control system.

CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability. Specifically, users should:
- When remote access is required, use secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is only as secure as its connected devices.
CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
CISA also provides a section for control systems security recommended practices on the ICS webpage on us-cert.cisa.gov. Several recommended practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
