IACS Radar assessment
Our own interpretation and context for this vulnerability — not an official source.
IACS Radar priority score
Based on CVSS 6.5, EPSS 0.2%, industrial relevance 45/100; raised due to relevance to internet exposure.
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
Operational impact & energy relevance
Limited impact on availability; the risk lies mainly with confidentiality or integrity of process data.
No strong energy-sector-specific signals recognised; general OT/ICS relevance.
This product uses protocols that are relevant to internet exposure analysis. An internet-reachable service is not automatically vulnerable.
Recommended defensive measures
Industrial relevance score
Classification is provisional; manual verification by an OT security analyst is recommended.
