- AutomatableyesAn attacker can reliably automate reconnaissance through exploitation, so this scales.
- Technical ImpactpartialSuccessful exploitation gives limited control of the vulnerable component.
- EPSS probability
- 7.74% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Equal to or higher than the score of 94.2% of scored records. A rank, not a probability.
- NVD base score
- 8.6 (CVSS v3.x), scored by the NVD independently of the CNA.
- NVD CVSS vector
- CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H
- NVD analysis status
