PhishingCVEVulnerabilityUpdateCritical

Overview

Rockwell Automation has identified several vulnerabilities in its CompactLogix, ControlLogix, Compact GuardLogix, and GuardLogix products that could allow attackers to cause a denial-of-service (DoS) condition. The affected versions include various models of CompactLogix and ControlLogix controllers, specifically those running versions V35.015 or lower for the 5370 and 5570 series, and V34.012 or V35.011 for the 5380, 5480, and 5580 series. If exploited, these vulnerabilities could lead to the devices entering a non-recoverable fault state, disrupting operations in critical manufacturing sectors. Users are urged to update their systems to the latest versions to mitigate these risks, as the vulnerabilities have a high severity rating (CVSS score of 8.6).

Recommended Practices CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities. 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. CISA also recommends users take the following measures to protect themselves from social engineering attacks: Do not click web links or open attachments in unsolicited email messages. Refer to Recognizing and Avoiding Email Scams for more information on avoiding email scams. Refer to Avoiding Social Engineering and Phishing Attacks for more information on social engineering attacks.
