03 Exploitation and scoring

Exploitation

Exploited in the wild. Listed in the CISA Known Exploited Vulnerabilities catalog on 2024-10-15. Federal remediation due 2024-11-05. 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 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

23.18% probability of exploitation activity in the next 30 days.

EPSS percentile

Equal to or higher than the score of 97.5% of scored records. A rank, not a probability.

NVD base score

9.8 (CVSS v3.x), scored by the NVD independently of the CNA.
