ASP.NET Misconfiguration: Event Validation Disabled

C#/VB.NET/ASP.NET

Abstract

禁用 ASP.NET 事件验证可能会允许攻击者提交未经授权或恶意的回发请求。

Explanation

事件验证是一项 ASP.NET 安全功能，它验证回发请求中的事件控制，以确保这些控制与加载初始页面期间呈现的控制相同。禁用此功能后，攻击者可能会通过篡改事件控制进行 Cross-Site Request Forgery 攻击，从而导致未经授权的访问、Cross-Site Scripting 攻击等。

示例 1：以下 Web 应用程序配置禁用事件验证。


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

示例 2：以下服务器页面指令禁用事件验证。


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