CVE-2025-1259Network attack vector

Restricted data disclosure via unauthorized gNOI requests

Published Mar 4, 2025 · Updated Mar 4, 2025

Improper access control in Arista EOS 4.28.0 through 4.33.1 allows remote authenticated users to retrieve restricted data through gNOI. The OpenConfig gNOI server accepts Get RPCs that its authorization policy should reject, exposing data beyond the caller's permitted access. Exposure requires OpenConfig with a gNOI server enabled; the disclosed consequence is read-only data exposure, with no reported integrity or availability impact.
