Vulnerabilidad en mongosqld: certificados de cliente no validados correctamente

mongosqld no valida correctamente los certificados de cliente durante el handshake TLS cuando está configurado con una autoridad certificadora. Esto permite que clientes sin certificado establezcan sesiones, comprometiendo la autenticación en entornos que dependen exclusivamente de certificados para identificar usuarios. Empresas en LATAM que utilizan MongoDB BI Connector con autenticación basada en certificados están expuestas a acceso no autorizado.
