How to fix?

Upgrade Oracle:7 kubeadm to version 0:1.14.9-1.0.6.el7 or higher.
This issue was patched in ELSA-2020-5765.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kubeadm package and not the kubeadm package as distributed by Oracle. See How to fix? for Oracle:7 relevant fixed versions and status.

The Kubernetes kube-apiserver in versions v1.6-v1.15, and versions prior to v1.16.13, v1.17.9 and v1.18.6 are vulnerable to an unvalidated redirect on proxied upgrade requests that could allow an attacker to escalate privileges from a node compromise to a full cluster compromise.
