界: Security Features

ソフトウェアのセキュリティは、セキュリティ ソフトウェアではありません。ここでは、認証、アクセス制御、機密性、暗号化、権限管理などのトピックについて説明します。

Cookie Security: HTTPOnly not Set on Application Cookie

Abstract
このプログラムは、HttpCookie.HttpOnly プロパティを true に設定しません。
Explanation
httpOnlyCookies 属性のデフォルト値は false です。これは、クライアント側のスクリプトを介して cookie にアクセスできることを意味します。これは Cross-Site Scripting の脅威となり、cookie が盗まれる可能性があります。盗まれた cookie には、ASP.NET セッション ID やフォーム認証チケットなど、サイトに対してユーザーを識別する機密情報が含まれている可能性があり、攻撃者がユーザーになりすましたり、機密情報を取得したりするために、再生される可能性があります。
例 1: 脆弱な設定:

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