Kubernetes API Server must disable token authentication to protect information in transit.

Description

<VulnDiscussion>Kubernetes token authentication uses password known as secrets in a plaintext file. This file contains sensitive information such as token, username and user uid. This token is used by service accounts within pods to authenticate with the API Server. This information is very valuable for attackers with malicious intent if the service account is privileged having access to the token. With this token a threat actor can impersonate the service account gaining access to the Rest API service.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
