## What is CVE-2023-24512?

CVE-2023-24512 is a high-severity missing authorization vulnerability in Arista Networks Terminattr, published on 25 Apr 2023. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

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
