The recent advisory issued by the Cybersecurity and Infrastructure Security Agency (CISA) on October 22, 2024, has highlighted a critical vulnerability in Industrial Control Systems (ICS) that could potentially lead to data breaches and unauthorized data tampering. The vulnerability specifically affects product suites from ICONICS and Mitsubishi Electric, raising concerns among ICS users and administrators worldwide.
The advisory, categorized under CVE-2024-7587 with a high severity CVSS v3.1 base score of 7.8, emphasizes the importance of addressing this vulnerability promptly. While the vulnerability is not exploitable remotely and requires local access to the system, the impact it could have on critical infrastructure is significant.
The root of the issue lies in incorrect default permissions (CWE-276) that could enable unauthorized users to access critical data, leading to potential data manipulation, information disclosure, and denial-of-service events. Given the widespread deployment of ICONICS and Mitsubishi Electric products in various industries, especially within the manufacturing sector, the potential risks associated with this vulnerability are substantial.
The affected products include ICONICS Suite products like GENESIS64, Hyper Historian, AnalytiX, and MobileHMI (version 10.97.3 and earlier), as well as Mitsubishi Electric’s MC Works64 across all versions. The advisory highlights the moderate to high risk posed by this vulnerability and underscores the importance of implementing mitigation strategies to safeguard critical data and ensure operational continuity.
To address this vulnerability, ICONICS and Mitsubishi Electric recommend specific mitigation steps for their users. These include upgrading to non-vulnerable versions, monitoring and correcting folder permissions, and applying security patches as they become available. Additionally, CISA offers proactive defense recommendations, urging organizations to conduct risk assessments, implement best practices for ICS cybersecurity, and stay updated on the latest security advisories and guidance.
While no public exploitation of this vulnerability has been reported to CISA thus far, organizations are advised to remain vigilant and report any suspicious activity. Early detection and swift action are crucial in mitigating the potential impact of vulnerabilities within critical infrastructure systems.
By following the guidelines outlined in the advisory, users can enhance the security of their ICS infrastructure and minimize the risk of exploitation. It is essential for organizations to prioritize cybersecurity measures and collaborate with agencies like CISA to ensure the resilience of critical infrastructure against evolving threats.
