03 Exploitation and scoring

Exploitation
Exploited in the wild. Listed in the CISA Known Exploited Vulnerabilities catalog on 2025-01-07. Federal remediation due 2025-01-28. Known ransomware campaign use: reported by CISA.
SSVC decision
  • ExploitationactiveCISA reports credible evidence of active exploitation.
  • AutomatableyesAn attacker can reliably automate reconnaissance through exploitation, so this scales.
  • Technical ImpactpartialSuccessful exploitation gives limited 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
38.15% probability of exploitation activity in the next 30 days.
EPSS percentile
Equal to or higher than the score of 98.5% of scored records. A rank, not a probability.
NVD base score
2.7 (CVSS v3.x), scored by the NVD independently of the CNA.
NVD CVSS vector
CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:N/A:N
