Risk evaluation: Successful exploitation of this vulnerability could allow an attacker to cause a denial-of-service on the affected products.
Critical infrastructure sectors: Critical Manufacturing
Countries/areas deployed: Worldwide
Company headquarters location: United States
Recommended Practices: CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability, such as:
Recommended Practices: Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet.
Recommended Practices: Locate control system networks and remote devices behind firewalls and isolating them from business networks.
Recommended Practices: 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.
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 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.
Recommended Practices: CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets.
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 exploitation specifically targeting this vulnerability has been reported to CISA at this time.
