ASP.NET Misconfiguration: Excessive Session Timeout
Abstract
Authentication 逾時時間過長會讓攻擊者獲得較多的時間，而可能危及使用者帳戶。
Explanation
開啟工作階段時間愈久，攻擊者威脅使用者帳戶的機率就愈大。工作階段仍為作用中時，攻擊者可能會暴力破解使用者密碼、破解使用者的無線加密金鑰，或是從開啟的瀏覽器控制工作階段。如果足夠大量的工作階段正在執行，較長的 authentication 逾時時間也會導致無法釋放記憶體，最後造成阻斷服務。
範例 1：以下範例顯示設定了 1 小時 authentication 逾時時間的 ASP.NET MVC。
如果逾時時間屬性尚未指定，則預設的 authentication 逾時時間為 30 分鐘。
範例 1：以下範例顯示設定了 1 小時 authentication 逾時時間的 ASP.NET MVC。
...
<configuration>
<system.web>
<authentication>
<forms
timeout="60" />
</authentication>
</system.web>
</configuration>
...
如果逾時時間屬性尚未指定，則預設的 authentication 逾時時間為 30 分鐘。
