  • COUNTRIES/AREAS DEPLOYED: Worldwide
  • COMPANY HEADQUARTERS LOCATION: United States

3.4 RESEARCHER

Rockwell Automation reported this vulnerability to CISA.

4. MITIGATIONS

Rockwell Automation recommends that users upgrade to one of the following versions:

  • Panel View Plus 7 Standard and Panel View Plus 7 Performance Series A v12, v13, v14 patch AID BF30506 (firmware fix)
  • Panel View Plus 7 Performance Series B V14.103

Users of the affected software who are unable to upgrade to one of the corrected versions should use Rockwell Automation's security best practices.

For more information, see the Rockwell Automation advisory SD1752 for this vulnerability.

CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability, 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 Virtual Private Network (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 Industrial Control Systems (ICS) webpage on cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving ICS 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 this vulnerability has been reported to CISA at this time.
