The vCenter Envoy service must set a limit on remote connections.
Medium Severity
<VulnDiscussion>Envoy client connections must be limited to preserve system resources and continue servicing connections without interruption. Without a limit set, the system would be vulnerable to a trivial denial-of-service attack where connections are created en masse and vCenter resources are entirely consumed. Envoy comes hard coded with a tested and supported value for "maxRemoteHttpsConnections" and "maxRemoteHttpConnections" that must be verified and maintained.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
