WCF Misconfiguration: Metadata

C#/VB.NET/ASP.NET

Abstract

메타데이터는 공격자가 시스템 정보를 알아내고 공격 형태를 결정하는 데 도움이 됩니다.

Explanation

WCF 서비스는 메타데이터를 노출하도록 구성될 수 있습니다. 메타데이터는 자세한 서비스 설명 정보를 제공하므로 운영 환경에서 브로드캐스트되어서는 안 됩니다. ServiceMetaData 클래스의 HttpGetEnabled / HttpsGetEnabled 속성은 서비스가 메타데이터를 노출할지 여부를 정의합니다.
예제 1: 다음 코드는 WCF가 서비스의 메타데이터를 브로드캐스트하도록 지시합니다.


    ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
    smb.HttpGetEnabled = true;
    smb.HttpGetUrl = new Uri(EndPointAddress);
    Host.Description.Behaviors.Add(smb);
