Cookie Security: Overly Broad Session Cookie Domain

Java/JSP
PHP

Abstract

Overly Broad Domain을 가진 세션 쿠키는 동일한 기본 도메인을 공유하는 응용 프로그램에 의해 접근할 수 있습니다.

Explanation

개발자는 흔히 세션 쿠키를 ".example.com"과 같은 기본 도메인이 되도록 설정합니다. 그러나 그렇게 하면 기본 도메인 이름 및 모든 하위 도메인의 모든 웹 응용 프로그램에 세션 쿠키가 노출됩니다. 세션 쿠키를 누출하면 계정이 손상될 수 있습니다.

예제 1:http://secure.example.com/에서 배포한 안전한 응용 프로그램이 있고 이 응용 프로그램이 사용자가 로그인할 때 ".example.com" 도메인을 사용하여 세션 쿠키를 설정한다고 가정하겠습니다.

응용 프로그램의 구성 파일에는 다음 항목이 있습니다.


server.servlet.session.cookie.domain=.example.com

http://insecure.example.com/에 덜 안전한 다른 응용 프로그램이 있으며 여기에는 Cross-Site Scripting 취약점이 있다고 가정합니다. http://insecure.example.com을 찾아보는 http://secure.example.com에 인증된 모든 사용자는 http://secure.example.com에서 해당 세션 쿠키를 노출할 위험이 있습니다.

Abstract

지나치게 광범위한 도메인을 가진 세션 쿠키는 동일한 기본 도메인을 공유하는 다른 응용 프로그램을 통해 공격받을 수 있습니다.

Explanation

개발자는 흔히 세션 쿠키를 ".example.com"과 같은 기본 도메인이 되도록 설정합니다. 그러면 기본 도메인 및 모든 하위 도메인의 모든 웹 응용 프로그램에 세션 쿠키가 노출됩니다. 응용 프로그램 전반에서 세션 쿠키를 공유하면 한 응용 프로그램의 취약점이 다른 응용 프로그램을 손상시킬 수 있습니다.

예제 1:http://secure.example.com/에서 배포한 안전한 응용 프로그램이 있고 이 응용 프로그램이 사용자가 로그인할 때 ".example.com" 도메인을 사용하여 세션 쿠키를 설정한다고 가정하겠습니다.

예:


session_set_cookie_params(0, "/", ".example.com", true, true);
