Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
On affected platforms running Arista MOS, the configuration of a BGP password will cause the password to be logged in clear text that can be revealed in local logs or remote logging servers by authenticated users, as well as appear in clear text in the device’s running config.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

On Arista MOS platforms, configuring a BGP password causes the plaintext password to be logged to local and remote logging destinations and also appears in cleartext in the device's running configuration. Any authenticated user with log access or config viewing privileges can retrieve the BGP password.

MitigationRemove BGP password configurations from BGP peers and migrate to more secure authentication methods such as keychains or certificate-based authentication. Rotate all exposed BGP passwords immediately.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check Arista MOS version
    Run 'show version' or 'version' command to obtain the installed MOS version number
    Affected if The installed version falls within 0.13.0 through 0.39.4 inclusive
  2. Identify BGP password configurations
    Run 'show running-config | grep -A 10 router bgp' or 'show ip bgp neighbor' to view BGP peer configurations
    Affected if Any BGP neighbor or peer-group has a 'password' or 'md5' configuration line present
  3. Examine logs for plaintext BGP passwords
    Review logs from 'show logging', check /var/log/messages, or remote syslog destinations for any entries containing the configured BGP password strings
    Affected if Log files contain plaintext strings matching the configured BGP password
  4. Verify running configuration for plaintext exposure
    Run 'show running-config' or 'show running-config section bgp' and inspect BGP sections for plaintext password values
    Affected if The BGP password appears in cleartext within the running configuration output rather than being masked or hidden

A user is affected if the Arista MOS version is between 0.13.0 and 0.39.4 AND BGP password authentication is configured, since the password would be exposed in logs and configuration.
