ASP.NET Misconfiguration: Persistent Authentication

C#/VB.NET/ASP.NET

Abstract

Persistent Authentication 許可證會讓使用者容易遭遇階段作業劫持攻擊。

Explanation

FormsAuthentication.RedirectFromLoginPage() 方法會發出 authentication 許可證，此許可證可讓使用者在特定的一段期間內維持驗證的身分。若將該方法的第二個參數設為 false，它會發出一個臨時的 authentication 許可證，其有效期在 web.config 中配置。若將第二個參數設為 true，此方法會發出 Persistent Authentication 許可證。在.NET 2.0 中，許可證的有效期為在 web.config 中配置的值，但在.NET 1.1 中，Persistent Authentication 許可證的有效期有個不可思議的預設值－ 50 年！

允許 Persistent Authentication 許可證長時期的存在，會讓使用者和系統容易遭遇以下幾種攻擊：

對那些沒有登出的使用者，Persistent Authentication 許可證延長了其暴露在階段作業劫持攻擊的時間。

Persistent Authentication 許可證增加了攻擊者猜中有效的階段作業識別碼的機率。

當攻擊者成功地劫持了使用者的階段作業後，這將使攻擊者有更多的時間來盜取資訊。
