Technical Description
An internal security review has identified an unauthenticated remote code execution vulnerability in Cloud Networking Operating System (CNOS)’ optional REST API management interface. This interface is disabled by default and not vulnerable unless enabled. When enabled, it is only vulnerable where attached to a VRF and as allowed by defined ACLs. Lenovo strongly recommends upgrading to a non-vulnerable CNOS release. Where not possible, Lenovo recommends disabling the REST API management interface or restricting access to the management VRF and further limiting access to authorized management stations via ACL.
Remediation
Check the references section for vendor advisories and patches from lenovo. Update cloud_networking_operating_system to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
