CVE-2025-3456

Estado: AplazadaBaja (3.8)—

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.
