WCF Misconfiguration: Unauthorized Access

C#/VB.NET/ASP.NET

Abstract

이 서비스는 권한 부여 제어를 사용하지 않습니다.

Explanation

클라이언트가 특정 WCF 서비스를 호출할 때, WCF는 호출자가 서버에서 service 메서드를 실행하는 권한을 가지는지 확인하는 다양한 권한 부여 스키마를 제공합니다. 권한 부여 제어가 WCF 서비스에 활성화되어 있지 않은 경우, 인증된 사용자가 권한 상승을 얻을 수 있습니다.

예제 1: 다음 코드는 WCF가 서비스 실행 시 클라이언트의 권한 부여 수준을 검사하지 않도록 지시합니다.


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