On affected platforms running Arista EOS, under certain circumstances plaintext shared secrets for configured Terminal Access Controller Access-Control System Plus (TACACS+) servers
AnalysisAI
Affected versions of Arista EOS can write plaintext TACACS+ shared secrets into a location an operator can read, exposing the secret that protects authentication traffic between the switch and its AAA servers. Exploitation is not remote: it requires a highly privileged local session (CVSS PR:H), a non-default/specific set of circumstances (AC:H), and a user action (UI:R), which is why the score sits at 6.3 despite high confidentiality, integrity, and availability metrics. …
