Technical ContextAI · show details

This vulnerability is classified under CWE-284. On affected platforms running Arista EOS, an authorized attacker with permissions to perform gNMI requests could craft a request allowing it to update arbitrary configurations in the switch. This situation occurs only when the Streaming Telemetry Agent (referred to as the TerminAttr agent) is enabled and gNMI access is configured on the agent. Note: This gNMI over the Streaming Telemetry Agent scenario is mostly commonly used when streaming to a 3rd party system and is not used by default when streaming to CloudVision Affected products include: Arista Eos, Arista Ceos-Lab, Arista Cloudeos, Arista Veos-Lab.
