ASP.NET Misconfiguration: Missing Error Handling

C#/VB.NET/ASP.NET

Abstract

為了避免攻擊者使用框架的內建錯誤回應來挖掘資訊，ASP .NET 應用程式必須啟用自訂的錯誤頁面。

Explanation

應設定 ASP .NET 應用程式使用自訂的錯誤頁面，而不是框架的預設頁面。預設的錯誤頁面會對所發生的錯誤提供詳細資訊，不應在生產的環境中使用。<customErrors> 標籤的 mode 屬性定義要使用自訂錯誤頁面還是預設錯誤頁面。

攻擊者可能利用預設的錯誤頁面所提供的額外資訊，來發動針對架構、資料庫或應用程式所使用的其他資源的攻擊。
