## Description

An uncontrolled resource consumption weakness exists in the request-handling path of the MongoDB sharded-cluster router process. A client that has network access to a router port and has not authenticated can supply connection-monitoring parameters that cause the server to expend CPU resources without any rate limiting, degrading or denying service to legitimate clients. No authentication, elevated privileges, or user interaction is required. Only availability is affected; data confidentiality and integrity are not impacted.
