Cookie Security: HTTPOnly not Set on Application Cookie

C#/VB.NET/ASP.NET

Abstract

이 프로그램은 HttpCookie.HttpOnly 속성을 true로 설정하지 않습니다.

Explanation

httpOnlyCookies 속성의 기본값이 false이면 클라이언트 측 스크립트를 통해 쿠키에 액세스할 수 있음을 의미합니다. 이는 불필요한 Cross-Site Scripting 위협이 되어 쿠키 도난으로 이어질 수 있습니다. 도난당한 쿠키에는 ASP.NET 세션 ID 또는 양식 인증 티켓과 같이 사이트 사용자를 식별하는 민감한 정보가 포함될 수 있으며 공격자는 이를 재생하여 사용자로 가장하거나 중요한 정보를 탈취할 수 있습니다.
예제 1: 취약한 구성:


<configuration>
  <system.web>
    <httpCookies httpOnlyCookies="false">
