Are Your Industrial Systems Protected Against Recent Cyber Threats?

In an alarm-raising cybersecurity advisory, the US Cybersecurity and Infrastructure Security Agency (CISA) has highlighted critical software vulnerabilities discovered in industrial devices from Rockwell Automation and Mitsubishi Electric. These vulnerabilities pose significant risks, including unauthorized access, data manipulation, and denial-of-service (DoS) conditions, and could be exploited remotely by cyber attackers. With such substantial threats, the need for stringent cybersecurity measures in industrial environments has never been more evident.

The vulnerabilities within Rockwell Automation’s FactoryTalk ThinManager are particularly concerning. Identified as CVE-2024-10386 and CVE-2024-10387, the flaws involve missing authentication for a critical function and out-of-bounds read, respectively. With Common Vulnerability Scoring System (CVSS) scores of 9.3 and 8.7, these vulnerabilities underline the potential for severe impact. Similarly, Mitsubishi Electric’s FA Engineering Software Products are affected by a major vulnerability, CVE-2023-6943, with an extremely high CVSS score of 9.8. This vulnerability allows malicious code execution remotely, resulting in unauthorized actions and potential DoS conditions. Additionally, CVE-2023-2060 in Mitsubishi Electric’s MELSEC iQ-R/iQ-F Series involves weak password requirements for an FTP function, making it susceptible to dictionary attacks or password sniffing.

Identified Vulnerabilities and Their Implications

The identification of these vulnerabilities underscores the critical nature of cybersecurity for industrial systems. Rockwell Automation’s FactoryTalk ThinManager, a widely-used software solution for managing thin client networks, presents two significant weaknesses. CVE-2024-10386 pertains to a missing authentication mechanism for key system functions, potentially allowing unauthorized users to gain control over the system. CVE-2024-10387, an out-of-bounds read vulnerability, could be exploited to extract confidential information or crash the system, disrupting industrial operations.

Mitsubishi Electric continues to face challenges with vulnerabilities in its products. CVE-2023-6943 in the FA Engineering Software Products allows remote attackers to execute harmful code, posing a grave risk to industrial control systems. The vulnerability’s high CVSS score highlights its potential impact on operational continuity and safety. The discovery of CVE-2023-2060 in the MELSEC iQ-R/iQ-F Series reveals another critical issue — inadequate password protection for the FTP function. This weakness opens the door for attackers to guess passwords through dictionary attacks, compromising system security.

Recommended Mitigation Strategies

The US Cybersecurity and Infrastructure Security Agency (CISA) has issued an alarming advisory about critical software vulnerabilities found in industrial devices from Rockwell Automation and Mitsubishi Electric. These security flaws are highly concerning because they enable unauthorized access, data manipulation, and denial-of-service (DoS) attacks, and they can be exploited remotely by cybercriminals. This situation underscores the urgent need for robust cybersecurity measures in industrial settings.

Specifically, Rockwell Automation’s FactoryTalk ThinManager has two troubling vulnerabilities, identified as CVE-2024-10386 and CVE-2024-10387. The first involves missing authentication for a critical function, while the second concerns an out-of-bounds read issue. With Common Vulnerability Scoring System (CVSS) scores of 9.3 and 8.7, these weaknesses highlight the risk’s severity. Similarly, Mitsubishi Electric’s FA Engineering Software Products face a severe vulnerability, CVE-2023-6943, with a high CVSS score of 9.8, which allows remote malicious code execution. Moreover, Mitsubishi’s MELSEC iQ-R/iQ-F Series are affected by CVE-2023-2060, involving weak FTP password requirements, making them vulnerable to dictionary attacks and password sniffing.
