Arista recommends customers move to the latest version of each release that contains all the fixes listed below. For more information about upgrading see EOS User Manual: Upgrades and Downgrades https://www.arista.com/en/um-eos/eos-upgrades-and-downgrades CVE-2024-27892 has been fixed in the following releases: * 4.31.3M and later releases in the 4.31.x train * 4.30.6M and later release in the 4.30.x train * 4.29.8M and later releases in the 4.29.x train * 4.28.11M and later releases in the 4.28.x train

Workaround

The workaround is to disable gNMI Set requests. This can be done by applying per RPC authorization and ensuring no user is authorized to run the OpenConfig.Set command. switch(config-gnmi-transport-default)#show management api gnmi transport grpc default authorization requests Alternatively, TLS can be disabled: switch(config-gnmi-transport-default)#no ssl profile Alternatively, the OpenConfig agent can be disabled entirely: switch(config-gnmi-transport-default)#no management api gnmi
