CVE-2025-3456: On affected platforms running Arista EOS, the global common encryption key configuration may be logged in clear text, in local or remote accounting logs. Knowle
Noroxi assessment
Priority: Monitor (action score 15/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.10% (FIRST EPSS).
- Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- According to the record, no fixed version is available yet.
Low priority for now. Update when a fix is released; follow the vendor's advisory.

Primary sources: NVD · CVE.org · FIRST EPSS
On affected platforms running Arista EOS, the global common encryption key configuration may be logged in clear text, in local or remote accounting logs. Knowledge of both the encryption key and protocol specific encrypted secrets from the device running-config could then be used to obtain protocol specific passwords in cases where symmetric passwords are required between devices with neighbor protocol relationships.
