Answer in brief
CVE-2025-3456 records a Low severity (CVSS 3.8) vulnerability in 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-c. The current sources do not mark it as known exploited. The current feed maps Arista Networks/EOS (generic). Check affected ranges and fixed versions before updating.

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.
