Rockwell Automation CompactLogix, ControlLogix, Compact GuardLogix and GuardLogix

All CISA Advisories

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.

Program to rotate cyber personnel through federal agencies saw little use

CyberScoop

The Government Accountability Office (GAO) reported that the Federal Rotational Cyber Workforce program, designed to rotate cybersecurity professionals among federal agencies, has seen minimal participation. Only a handful of personnel received approval to join the initiative, which aims to enhance collaboration and knowledge sharing across government entities. This low engagement raises concerns about the effectiveness of the program in addressing the growing cybersecurity challenges faced by federal agencies. Without a more robust participation rate, the program may struggle to achieve its intended goals of improving cyber defense capabilities and developing a skilled workforce. The findings suggest a need for better incentives or support to encourage agencies to utilize this resource effectively.

Phishing Campaign Hides Lua Loader as TrueType Font File

Infosecurity Magazine

A global phishing campaign has been detected that disguises a Lua loader as a TrueType font file to deploy remote access Trojans (RATs) and information stealers. Attackers are using this method to bypass security measures by making the malicious files appear innocuous. This tactic affects users who may inadvertently open these disguised files, leading to potential data breaches or unauthorized access to systems. The presence of such sophisticated phishing techniques raises concerns about the effectiveness of traditional email security measures. Users need to be vigilant about unexpected email attachments, even if they seem harmless, to avoid falling victim to these types of attacks.
