WCF Misconfiguration: Debug Information

C#/VB.NET/ASP.NET

Abstract

디버깅 정보는 공격자가 시스템을 파악하고 공격 형태를 계획하는 데 도움이 됩니다.

Explanation

디버깅 정보를 노출하도록 WCF(Windows Communication Framework) 서비스를 구성할 수 있습니다. 운영 환경에서는 디버그 정보를 사용하면 안 됩니다. <serviceDebug> 태그는 WCF 서비스에 대해 디버그 정보 기능을 활성화할지 여부를 정의합니다.

includeExceptionDetailInFaults 속성이 true로 설정된 경우 응용 프로그램의 예외 정보가 클라이언트로 반환됩니다. 공격자는 디버깅 출력에서 얻은 자세한 정보를 이용하여 응용 프로그램이 사용하는 프레임워크, 데이터베이스 또는 기타 리소스를 공격할 수 있습니다.

예제: 다음 구성 파일에는 <serviceDebug> 태그가 포함되어 있습니다.


<configuration>
  <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior name="MyServiceBehavior">
          <serviceDebug includeExceptionDetailInFaults="True" httpHelpPageEnabled="True"/>
...
