Update Summary

This updated advisory is a follow-up to the original advisory titled ICSA-19-346-02 Omron PLC CJ and CS Series (Update A) published November 29, 2022, on the ICS webpage at cisa.gov.

Risk evaluation

Successful exploitation of these vulnerabilities could allow an attacker to pose as an authorized user to obtain the status information of the PLC.

Critical infrastructure sectors

Critical Manufacturing

Countries/areas deployed

Worldwide

Company headquarters location

Japan

Recommended Practices

CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities. Specifically, users should:

Recommended Practices

Minimize network exposure for all control system devices and/or systems, and ensure they are not accessible from the Internet.

Recommended Practices

Locate control system networks and remote devices behind firewalls and isolate them from business networks.

Recommended Practices

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.

Recommended Practices

CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.

Recommended Practices

CISA also provides a section for control systems security recommended practices on the ICS webpage at cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.

Recommended Practices

Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies.

Recommended Practices

Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.

Recommended Practices

No known public exploits specifically target these vulnerabilities.
