Description

A flaw was found in the Windows Machine Config Operator (WMCO) for Red Hat OpenShift Container Platform.

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.
