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.
- AutomatableyesAn attacker can reliably automate reconnaissance through exploitation, so this scales.
- Technical ImpacttotalSuccessful exploitation gives total control of the vulnerable component.
- EPSS probability
- 0.67% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Equal to or higher than the score of 52.0% of scored records. A rank, not a probability.
- NVD base score
- 9.8 (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:U/C:H/I:H/A:H
- NVD analysis status
- Deferred. NVD last modified this record on 2026-09-18.
- Red Hat severity
- No Red Hat rating. Red Hat rates the CVEs that affect its products.
Exploit-prediction scores from FIRST. Independent scoring and analysis status from the NVD. Vendor severity from Red Hat. Exploitation assessment and catalog membership from CISA.

07 Remediation
Customers running the affected end-of-life firmware should contact FatPipe Support to upgrade their appliances to the latest supported software release. The vulnerability has been addressed in current FatPipe software, and a remediated release is already available. As an interim mitigation pending the upgrade, leave the affected management interface disabled if it is not required, restrict management access to trusted administrative networks, use WAN access control lists to permit connections only from authorized source addresses, and avoid exposing the management interface directly to the public Internet.
