Vulnerability Description
On affected platforms running Arista EOS, under certain circumstances plaintext private keys may be written in clear text to log files during operations when specialized non-standard debugging trace levels are explicitly enabled. To exploit these vulnerabilities, a malicious actor must already possess authenticated local administrative access to the device shell, and specialized non-standard debugging trace levels must be explicitly enabled.
