ASP.NET Misconfiguration: Trace Output

C#/VB.NET/ASP.NET

Abstract

トレースデバッグ情報は、攻撃者にシステムの情報を教え、攻撃形態の計画を助けることにつながります。

Explanation

ASP.NET アプリケーションは、トレースデバッグ情報を出力するように設定できます。Trace Output には、現在のページに対して行われたリクエスト、ヘッダー情報、ページで使用されたメソッドおよびコントロール、そしてアクティブセッションの状態が含まれます。攻撃者はトレース出力から得た追加情報を利用して、フレームワークやデータベースなど、アプリケーションで使用されるリソースを標的に攻撃を仕掛けることがあります。

トレース情報は、<page> ディレクティブの Trace 属性を true に設定することによってページレベルで有効にするか、web.config ファイルに trace 要素を追加し、enabled 属性を true にすることによってアプリケーションレベルで有効にします。
