Kubernetes Controller Manager must have the SSL Certificate Authority set.
Medium Severity
<VulnDiscussion>The Kubernetes Controller Manager is responsible for creating service accounts and tokens for the API Server, maintaining the correct number of pods for every replication controller and provides notifications when nodes are offline. Anyone who gains access to the Controller Manager can generate backdoor accounts, take possession of, or diminish system performance without detection by disabling system notification. Using authenticity protection, the communication can be protected against man-in-the-middle attacks/session hijacking and the insertion of false information into sessions. The communication session is protected by utilizing transport encryption protocols, such as TLS. TLS provides the Kubernetes Controller Manager with a means to be able to authenticate sessions and encrypt traffic.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
