ASP.NET Misconfiguration: Excessive Session Timeout

C#/VB.NET/ASP.NET

Abstract

身份验证超时过长可延长攻击者对用户帐户造成潜在危害的时间。

Explanation

会话处于打开状态的时间越长，攻击者破坏用户帐户的机会窗口越大。会话保持活动状态期间，攻击者可以强力破解用户的密码、破解用户的无线加密密钥或控制打开的浏览器会话。如果创建足够多的会话，身份验证超时较长还可能阻止内存释放，最终引发 Denial of Service 攻击。

示例 1：以下示例显示了身份验证超时配置为 1 小时的 ASP.NET MVC。


...
<configuration>
  <system.web>
  <authentication>
    <forms
      timeout="60" />
  </authentication>
  </system.web>
</configuration>
...

如果未指定超时属性，则身份验证超时默认为 30 分钟。
