ASP.NET Misconfiguration: Persistent Authentication

C#/VB.NET/ASP.NET

Abstract

Tíquetes de autenticação persistentes deixam os usuários vulneráveis a sequestros de sessão.

Explanation

O método FormsAuthentication.RedirectFromLoginPage() emite um tíquete de autenticação, que permite que os usuários permaneçam autenticados por um período de tempo especificado. Quando o método é invocado com o segundo argumento false, ele emite um tíquete de autenticação temporário que permanece válido por um período de tempo configurado em web.config. Quando invocado com o segundo argumento true, o método emite um tíquete de autenticação persistente. No .NET 2.0, o tempo de vida do tíquete persistente respeita o valor em web.config, mas, no .NET 1.1, esse tíquete de autenticação persistente tem um tempo de vida padrão ridiculamente longo -- cinquenta anos.

Permitir que tíquetes de autenticação persistentes sobrevivam por um longo período de tempo deixa os usuários e o sistema vulneráveis das seguintes maneiras:

Expande o período de exposição a ataques de sequestro de sessão para usuários que não conseguem fazer logout.

Aumenta o número médio de identificadores de sessão válidos disponíveis para um invasor adivinhar.

Prolonga a duração da exploração quando um invasor consegue sequestrar a sessão de um usuário.
