이 섹션에는 소스 코드 외부에 있지만 제작 중인 제품의 보안에는 여전히 중요한 내용이 모두 포함되어 있습니다. 이 섹션에서 다루는 문제들은 소스 코드와 직접적으로 관련이 없기 때문에 나머지 섹션과 분리했습니다.

J2EE Misconfiguration: Direct JSP Access

Java/JSP

Abstract

Java Server Pages에 대한 직접 액세스는 시스템 정보 누출, 소스 코드 공개 및 임의 코드 실행으로 이어질 수 있습니다.

Explanation

작업 또는 서블릿을 사용하여 JSP(Java Server Page)에 요청을 위임하는 웹 프레임워크로 구축된 Struts 또는 Spring과 같은 응용 프로그램에서 JSP에 직접 액세스하면 처리되지 않은 예외 및 시스템 정보 누출이 발생할 수 있습니다. 불완전하게 구현되거나 구성된 응용 프로그램 서버는 http://host/page.jsp%00 또는 http://host/page.js%2570과 같이 특수하게 고안된 요청을 사용하여 소스 코드 세부 정보를 유출하는 데 악용되어 왔습니다. 더 심한 경우, 응용 프로그램에서 사용자가 임의의 파일을 업로드하도록 허용할 경우, 공격자는 이 메커니즘을 사용하여 JSP의 형태로 악성 코드를 업로드하고 업로드한 페이지에서 악성 코드가 서버에서 실행되도록 요청할 수 있습니다.

예제 1: 다음 예제는 잘못 구성된 보안 제약 조건을 보여줍니다. 이 보안 제약 조건은 해당하는 웹 리소스에 모든 사용자가 액세스하는 것을 허용함을 나타내는 ‘*’를 사용하여 역할 이름에 JSP에 대한 직접 액세스를 명시적으로 허용합니다.
