ASP.NET Misconfiguration: Incomplete Role Protection

C#/VB.NET/ASP.NET

Abstract

cookie 内の保護されていないロール情報は、攻撃者によって表示または変更される可能性があります。

Explanation

web.config にある configuration/system.web/authentication/forms 要素の cacheRolesInCookie 属性が true に設定されている場合、各ユーザーのロールは cookie にキャッシュされます。この情報が平文で保存されていると、アプリケーションとの対話に使用されるマシンにアクセスできる人であれば、誰でも cookie に保存されている情報にアクセスできます。さらに、攻撃者が cookie に保存されているデータを任意に変更することを許可されている場合、攻撃者はアプリケーションに提供された情報を改ざんし、その動作を思いどおりに変更できてしまいます。

多くの場合、アプリケーションは cookie からの入力を、使用されるコンテキストに応じてプログラミングで検証できますが、ASP.NET の検証フレームワークは、cookie に想定外の変更が加えられていないことを確認するための優れた手法を提供します。このアプローチがなければ、すべての入力が検証されていることを高いレベルの信頼性で確立することは困難であり、多くの場合不可能です。
