계: Encapsulation

캡슐화는 강력한 경계를 그리는 것입니다. 웹 브라우저에서는 사용자의 모바일 코드가 다른 모바일 코드에 의해 오용되지 않도록 하는 것을 의미합니다. 서버에서는 검증된 데이터와 검증되지 않은 데이터, 한 사용자의 데이터와 다른 사용자의 데이터, 데이터 사용자가 볼 수 있는 데이터와 볼 수 없는 데이터 간의 차별화를 의미할 수 있습니다.

System Information Leak: HTML Comment in JSP

Java/JSP

Abstract

HTML 주석에 노출된 정보는 공격자가 시스템을 파악하고 공격 계획을 세우는 데 도움이 됩니다.

Explanation

HTML 주석은 공격자에게 동적으로 생성된 웹 페이지에 대한 쉬운 소스 정보를 제공합니다.

예제 1:


<!-- TBD: this needs a security audit -->
<form method="POST" action="recalcOrbit">
...

무해하게 보이는 주석이라도 시스템이 실행되는 방법을 이해하려는 사용자에게는 유용할 수 있습니다.
