Un cliente de red sin autenticar puede mantener abierta indefinidamente una sesión de autenticación SASL en MongoDB Connector for BI, bloqueando workers y slots de conexión del servidor. Esto facilita ataques de denegación de servicio (DoS) que pueden afectar la disponibilidad de plataformas de Business Intelligence y análisis de datos altas en empresas de LATAM que dependan de este conector.
A network-reachable client that has not yet authenticated can hold a MongoDB Connector for BI authentication session open indefinitely by beginning a SASL-based login exchange and then declining to complete it. Because the negotiation loop had no overall time bound and the read from the client had no deadline, each such session retains a worker, a client connection slot, and its associated backend database connections until the process is restarted. Repeated use of this behavior can consume the configured connection capacity and prevent legitimate users from establishing new sessions.
