ASP.NET Misconfiguration: Persistent Authentication

C#/VB.NET/ASP.NET

Abstract

Persistent authentication 票据使用户容易受到会话劫持攻击。

Explanation

FormsAuthentication.RedirectFromLoginPage() 方法会发布一个 authentication 票据，该票据使用户可以在一段时期内保留经过验证的身份。如果将该方法的第二参数设为 false，则调用该方法时会发布一个临时 authentication 票据，其有效期在 web.config 中配置。如果将第二参数设为 true，该方法就会发布一个 persistent authentication 票据。在 .NET 2.0 中，persistent authentication 票据的有效期就是在 web.config 中配置的值；但在 .NET 1.1 中，persistent authentication 票据的有效期有一个滑稽的默认值 - 50 年。

允许 persistent authentication 票据长时期存在会使用户和系统容易受到以下几种攻击：

对于注销失败的用户，身份验证票据漏洞延长了其暴露在会话劫持攻击下的时间。

持久身份验证票据增加了攻击者猜中正确的会话标识符的机率。

当攻击者成功地劫持了某个用户的会话后，该漏洞将使攻击者有更多的时间来盗取信息。
