CVE-2025-54546Network attack vector

Authenticated internal-service access via SSH port forwarding

Published Oct 29, 2025 · Updated Oct 29, 2025

Incorrect permission assignment in Arista DANZ Monitoring Fabric 8.7.0 and earlier allows remote authenticated users to reach host-internal services. The SSH service authorizes TCP port forwarding for a restricted CLI role, allowing tunnels through the appliance to services otherwise confined to the host. Exploitation requires valid local or TACACS+/RADIUS-backed non-administrator credentials and CLI access; the consequence is limited by the internal services reachable from the affected host.
