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.
The recommended resolution is to upgrade to a remediated software version at your earliest convenience. Arista recommends customers move to the latest version of each release that contains all the fixes listed below. For more information about upgrading see the MOS User Guide: Updating https://mako.arista.com/dyn/softwareportal/artefact/3688/mos-0.39.1-userguide.pdf CVE-2023-24547 has been fixed in the following releases: * MOS-0.36.10 and later releases in the MOS-0.36.x train * MOS-0.39.4 and later releases in the MOS-0.39.x train Because this issue would cause the password to be saved in logs and remote AAA servers it is recommended to also rotate the BGP password, if possible.
