ASP.NET Misconfiguration: Missing Error Handling

C#/VB.NET/ASP.NET

Abstract

ASP .NET 应用程序必须启用自定义错误页面，以防止攻击者从框架的内置错误响应中挖掘信息。

Explanation

ASP .NET 应用程序应配置为使用自定义错误页面而不是框架默认页面。默认错误页面提供有关所发生错误的详细信息，不应在生产环境中使用。<customErrors> 标签的 mode 属性定义是使用自定义还是默认错误页面。

攻击者可以利用默认错误页面提供的附加信息，对应用程序所用的框架、数据库或其他资源发动攻击。
