SUBNET PowerSYSTEM Server and Substation Server Reliance on Insufficiently Trustworthy Component

03 Exploitation and scoring

Exploitation
Assessed, none found. CISA's assessment recorded neither public exploit code nor evidence of exploitation when it was made.
SSVC decision
  • ExploitationnoneCISA recorded no public exploit code and no evidence of exploitation.
  • AutomatablenoAt least one step from reconnaissance to exploitation cannot be reliably automated.
  • Technical ImpacttotalSuccessful exploitation gives total control of the vulnerable component.
CISA publishes the decision points, not a final SSVC decision. The decision also depends on mission and well-being impact, which is a property of your deployment rather than of the vulnerability.
EPSS probability
0.25% probability of exploitation activity in the next 30 days.
EPSS percentile
Equal to or higher than the score of 16.9% of scored records. A rank, not a probability.
NVD base score
8.6 (CVSS v4.0), scored by the NVD independently of the CNA.
