How to fix?

There is no fixed version for RHEL:7 openshift4-wincw/windows-machine-config-rhel8-operator.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openshift4-wincw/windows-machine-config-rhel8-operator package and not the openshift4-wincw/windows-machine-config-rhel8-operator package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

A flaw was found in the Windows Machine Config Operator (WMCO) for Red Hat OpenShift Container Platform. WMCO establishes SSH connections to Windows worker nodes without verifying the remote server host key. An adjacent-network attacker who can intercept or redirect WMCO's SSH session can capture WICD and kubelet bootstrap credentials transferred during node configuration, enabling compromise of Windows node identities in the cluster.
