Arista EOS switches can write plaintext private keys into log files when specialized, non-standard debugging trace levels are explicitly enabled on the device. Exploitation requires an attacker to already hold authenticated local administrative access to the device shell and to have those special debug trace levels turned on, so the practical exposure is primarily insider or post-compromise rather than remote. Arista discovered the flaw internally (SA-0153), states it is unaware of malicious exploitation in customer networks, and the issue is not listed in CISA KEV and no public exploit code has been identified.

Lifecycle Timeline
1DescriptionCVE.org
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.
This issue was discovered internally by Arista, and the company is not aware of any malicious exploitation of this vulnerability in customer networks.
