IACS Radar priority score

49/ 100

Based on CVSS 9.8, EPSS 1.4%, industrial relevance 40/100.

Combines CVSS, EPSS, KEV status, industrial relevance and exposure relevance — a complement to, not a replacement for, the individual scores below and above.

Conditions for exploitation

•Network access to the affected device or segment is required.
•No valid credentials are needed.
•No user interaction required.

Operational impact & energy relevance

Possible loss of visibility of or control over the process upon successful exploitation.

No strong energy-sector-specific signals recognised; general OT/ICS relevance.

Recommended defensive measures

•Limit user rights to what is strictly necessary through role-based access.
•Implement network segmentation in line with zones and conduits (IEC 62443-3-2).
•Encrypt sensitive configuration and management communication.
•Restrict network access to the affected device to a dedicated OT management segment.

Industrial relevance score

40/ 100

• Mentioned in an official CISA ICS advisory, which confirms direct relevance to industrial control systems.

Classification is provisional; manual verification by an OT security analyst is recommended.

Classified by IACS Radar-analysepijplijn (geautomatiseerd) on 7 November 2026.
