The Cybersecurity and Infrastructure Security Agency (CISA) has released two significant advisories focused on Industrial Control Systems (ICS), urging swift action from organizations operating within vital infrastructure sectors. These advisories—ICSA-25-091-01 and ICSA-24-331-04—highlight newly discovered vulnerabilities that could pose severe threats if left unaddressed.
ICSA-25-091-01 focuses on a critical vulnerability affecting Rockwell Automation's Lifecycle Services, which integrate with Veeam Backup and Replication. This issue stems from improper deserialization of untrusted data (CWE-502)—a known risk that allows remote attackers to execute malicious code. The flaw has received a CVSS v4 score of 9.4, indicating a high-severity, low-complexity threat that is remotely exploitable.
Impacted products include:
- Industrial Data Center (IDC) with Veeam (Generations 1-5)
- VersaVirtual Appliance (VVA) with Veeam (Series A-C)
If exploited, the vulnerability could give attackers with admin rights full access to execute arbitrary code, potentially leading to complete system takeover.
"CISA urges organizations to take immediate defensive measures to mitigate the risk, including:
• Minimizing network exposure for all control systems and ensuring they are not directly accessible from the internet.
• Using secure access methods like Virtual Private Networks (VPNs) when remote access is necessary.
• Keeping VPNs up to date to prevent vulnerabilities from being exploited."
Rockwell Automation is collaborating with CISA to inform affected clients—especially those under Infrastructure Managed Service contracts—about available patches and remediation steps.
ICSA-24-331-04 draws attention to multiple security flaws in Hitachi Energy’s MicroSCADA Pro/X SYS600, a system widely used in energy and manufacturing sectors. These vulnerabilities include improper query logic handling, session hijacking via authentication bypass, and path traversal risks.
The most critical issue, CVE-2024-4872, carries a CVSS v3 score of 9.9, making it one of the most severe. It enables attackers with valid credentials to inject harmful code into the system, risking unauthorized access and corruption of persistent data.
Other issues include:
- CVE-2024-3980: Lack of proper file path limitations
- Exposure to further system compromise if not promptly patched
"Hitachi Energy has released patches for the affected versions, including a critical update to Version 10.6 for MicroSCADA Pro/X SYS600. Users are also advised to apply necessary workarounds and stay updated with security patches to protect against exploitation."
CISA strongly advises organizations using these systems to implement all recommended mitigations without delay to minimize potential risks.
