03 Exploitation and scoring
SRC: CISA, FIRST, NVD, RED HAT- Exploitation

- 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
- 0.11% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Ranks above 1.3% of scored records. A rank, not a probability.
- NVD base score
- 3.7 (CVSS v3.x), scored by the NVD independently of the CNA.
- NVD CVSS vector
- CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N
- NVD analysis status
