Prose
The Kubernetes cluster must use non-privileged host ports for user pods.
Medium Severity
<VulnDiscussion>Privileged ports are those ports below 1024 and that require system privileges for their use. If containers can use these ports, the container must be run as a privileged user. Kubernetes must stop containers that try to map to these ports directly. Allowing non-privileged ports to be mapped to the container-privileged port is the allowable method when a certain port is needed. An example is mapping port 8080 externally to port 80 in the container.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
