3.4 RESEARCHER

Tenable Network Security reported these vulnerabilities to Rockwell Automation.

4. MITIGATIONS

Rockwell Automation has provided a fix for the affected versions on the FactoryTalk ThinManager download site.

Rockwell Automation encourages users of the affected software to apply these risk mitigations if possible.

• Implement network hardening for ThinManager Device(s) by limiting communications to TCP 2031 to only the devices that need connection to the ThinManager.
• For information on how to mitigate security risks on industrial automation control systems, users are encouraged to implement Rockwell Automation’s suggested security best practices to minimize the risk of the vulnerability.

For more information, see Rockwell Automation’s security bulletin.

CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities, such as:

• Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet.
• Locate control system networks and remote devices behind firewalls and isolating them from business networks.
• When remote access is required, use more 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 the 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 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.

CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets.

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.

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

No known public exploitation specifically targeting these vulnerabilities has been reported to CISA at this time.
