WCF Misconfiguration: Unauthorized Access

C#/VB.NET/ASP.NET

Abstract

Este servicio no utiliza un control de autorización.

Explanation

Cuando un cliente llama a un servicio WCF en concreto, WCF proporciona varios esquemas de autorización que comprueban que el autor de llamada tiene permiso para ejecutar el método de servicio en el servidor. Si los controles de autorización no están activados para los servicios WCF, un usuario autenticado puede obtener la remisión del privilegio.

Ejemplo 1: el siguiente código indica a WCF que no compruebe el nivel de autorización del cliente al ejecutar el servicio:


    ServiceHost myServiceHost = new ServiceHost(typeof(Calculator), baseUri);
    ServiceAuthorizationBehavior myServiceBehavior =
    myServiceHost.Description.Behaviors.Find<ServiceAuthorizationBehavior>();
    myServiceBehavior.PrincipalPermissionMode =
        PrincipalPermissionMode.None;
