Description
On affected platforms running Arista EOS, if OpenConfig is configured and running a gNMI server on the system, and if gNSI Pathz is configured and a gNSI Pathz policy is present on the system, then gNMI may fail to correctly enforce the rules in this policy if both a group rule and a user rule for the same path is present in the policy. Under certain conditions, this can lead to an authenticated user gaining unauthorized permission to read or write gNMI paths that the Pathz policy is intended to restrict.
Affected products
- Arista Networks EOS: from 4.33.2F through 4.33.8M; from 4.34.0F through 4.34.6M; from 4.35.0F through 4.35.5M; from 4.36.0F through 4.36.0.1F
