ASP.NET Misconfiguration: Excessive Session Timeout

C#/VB.NET/ASP.NET

Abstract

Un tiempo de espera de autenticación demasiado largo les da a los atacantes más tiempo para comprometer potencialmente las cuentas de los usuarios.

Explanation

Cuanto más tiempo permanece abierta una sesión, mayor es la ventana de oportunidad que tiene un atacante para comprometer las cuentas de usuario. Mientras una sesión permanece activa, un atacante puede forzar la contraseña de un usuario, descifrar su clave de cifrado inalámbrica o controlar una sesión desde un explorador abierto. Los tiempos de espera de autenticación más prolongados también pueden evitar que se libere la memoria y acabar en una denegación de servicio si se crea una cantidad suficientemente grande de sesiones.

Ejemplo 1: El siguiente ejemplo muestra ASP.NET MVC configurado con un tiempo de espera de autenticación de una hora.


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

Si no se especifica el atributo de tiempo de espera, el tiempo de espera de autenticación predeterminado es de 30 minutos.
