03 Exploitation and scoring
SRC: CISA, FIRST, NVD, RED HAT- Exploitation
- Not assessed. CISA has not published an exploitation assessment for this record, and it is not in the KEV catalog. That is an absence of assessment, not a finding of no risk.
- SSVC decision
- Not assessed by CISA
- EPSS probability
- 5.53% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Ranks above 92.2% 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
- Modified. NVD last modified this record on 2026-06-17.
- 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.

SRC: CNA
* Update firmware. Update EN2* ControlLogix communications modules to mitigated firmware.
* Properly segment networks. Given a cyber actor would require network connectivity to the communication module to exploit the vulnerability, organizations should ensure ICS/SCADA networks are properly segmented within the process structure as well as from the Internet and other non-essential networks.
* Implement detection signatures. Use appended Snort signatures to monitor and detect anomalous Common Industrial Protocol (CIP) packets to Rockwell Automation devices.
