The Cybersecurity and Infrastructure Security Agency (CISA) recently issued two critical Industrial Control Systems (ICS) advisories on October 15, 2024, addressing security concerns, vulnerabilities, and potential exploits affecting ICS systems worldwide.

The first advisory focuses on vulnerabilities found in Siemens Siveillance Video Cameras, highlighting a significant flaw classified as a “Classic Buffer Overflow.” This vulnerability, with a Common Vulnerability Scoring System (CVSS) v4 score of 7.3, poses a high risk to systems utilizing Siemens Siveillance Video Cameras. The affected products include all versions before V13.2, and the vulnerability, identified as CVE-2024-3506, involves a buffer overflow issue in the camera’s drivers from the XProtect Device Pack. Exploiting this vulnerability could allow attackers with network access to execute arbitrary commands on the Recording Server, potentially compromising critical infrastructure sectors where these cameras are deployed globally.

The second advisory addresses vulnerabilities in Schneider Electric’s Data Center Expert software, specifically “Improper Verification of Cryptographic Signature” and “Missing Authentication for Critical Function.” These vulnerabilities, with respective CVSS v4 scores of 8.6 and 8.2, are critical in nature. Affected versions include Data Center Expert 8.1.1.3 and earlier. The improper cryptographic signature verification (CVE-2024-8531) could enable attackers to manipulate upgrade bundles and execute unauthorized bash scripts as root. Similarly, the missing authentication for critical functions (CVE-2024-8530) could lead to exposure of private data by allowing direct access to “log captures” archives through HTTPS. Exploiting these vulnerabilities could grant attackers unauthorized access to sensitive data and control over critical functions within data centers, posing significant risks to organizations relying on this software for data infrastructure management.

CISA emphasizes the urgency for users and administrators of Siemens Siveillance Video Cameras and Schneider Electric Data Center Expert software to carefully review these advisories and implement recommended mitigations to protect against potential cyber threats exploiting these vulnerabilities. The release of these advisories underscores the ongoing challenges in securing industrial control systems against cyber threats.

As cyber attackers increasingly target critical infrastructure, staying informed, and proactive measures are crucial for organizations to defend against potential exploits and ensure the integrity of their operations in an evolving digital landscape. Implementing security best practices and adhering to security advisories remain essential components of safeguarding sensitive systems and upholding cybersecurity resilience in the face of emerging threats.
