ASP.NET Misconfiguration: Missing Error Handling

C#/VB.NET/ASP.NET

Abstract

ASP .NET 응용 프로그램의 경우, 공격자가 프레임워크의 기본 제공 오류 응답에서 정보를 빼내는 것을 막기 위해 사용자 지정 오류 페이지를 사용해야 합니다.

Explanation

ASP .NET 응용 프로그램은 프레임워크 기본 페이지 대신 사용자 지정 오류 페이지를 사용하도록 구성되어야 합니다. 기본 오류 페이지는 발생한 오류에 대한 자세한 정보를 제공하므로 운영 환경에서 사용해서는 안 됩니다. <customErrors> 태그의 mode 속성은 사용자 지정 오류 페이지와 기본 오류 페이지 중 어느 것을 사용할지 결정합니다.

공격자는 기본 오류 페이지에서 얻은 자세한 정보를 이용하여 응용 프로그램이 사용하는 프레임워크, 데이터베이스 또는 기타 리소스를 공격할 수 있습니다.
