軟體安全性並非安全性軟體。我們關注驗證、Access Control、保密性、加密以及權限管理之類的主題。

ASP.NET Misconfiguration: Event Validation Disabled

C#/VB.NET/ASP.NET

Abstract

停用 ASP.NET 事件驗證可能會允許攻擊者提交未經授權或惡意的回傳 (postback) 要求。

Explanation

事件驗證是一項 ASP.NET 安全功能，它會驗證回傳 (postback) 要求中的事件控制項，以確保這些控制項與初始頁面載入期間呈現的控制項相同。停用此功能後，攻擊者可能會透過竄改事件控制項進行 Cross-Site Request Forgery 攻擊，從而導致未經授權的存取、Cross-Site Scripting 攻擊等。

範例 1：以下 Web 應用程式組態停用了事件驗證。


...
<system.web>
    ...
    <pages enableEventValidation="false">
    ...
    </pages>
</system.web>

範例 2：以下伺服器頁面指令停用了事件驗證。


<%@ Page ... EnableEventValidation="false" %>
