"The following text was originally created by the Cybersecurity and Infrastructure Security Agency (CISA). The original
can be found at CISA.gov.

ABB recommends users update to the following or later versions at earliest convenience if IEC 61850 is used:

- Relion 670 series version 1p1r27
- Relion 670 series version 1.2.3.18
- Relion 670 series version 2.0.0.11 (RES670 2.0.0.5)
- Relion 670 series version 2.1.0.2

Updates can be ordered by email at: [email protected]

The only known workaround for this vulnerability is to disable IEC 61850 protocol when not in use. If this is not
possible, ABB recommends having a proper security architecture that divides the system in different security zones, and
revising the firewall configurations to limit the usage of MMS protocol to the relevant upper networks.

IEC 61850 MMS protocol uses Port 102/TCP.

ABB also recommends that these and other proper security practices and firewall configurations (including VPN) be
implemented to help protect a process control network from attacks originating outside the network:

- Process control systems are physically protected from direct access by unauthorized personnel.
- Process control systems have no direct connections to the Internet.
- Process control systems are separated from other networks by means of a firewall system that has a minimal number of
ports/services exposed.
- 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.
- If IEC 61850 protocol isn’t used, make sure it is disabled. This removes the vulnerability.
