IACS Radar priority score
Based on CVSS 8.6, EPSS 0.5%, industrial relevance 60/100; 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
Possible loss of visibility of or control over the process upon successful exploitation.
Assessed as relevant to the energy sector based on: Vermeld in een officiële CISA ICS Advisory, wat directe relevantie voor industriële besturingssystemen bevestigt. Vendor "Phoenix Contact" is a known supplier of equipment for the energy sector. Description mentions industrial protocol: ssh.
This product uses protocols that are relevant to internet exposure analysis. An internet-reachable service is not automatically vulnerable.
