ASP.NET Misconfiguration: Excessive Session Timeout

C#/VB.NET/ASP.NET

Abstract

Um tempo limite de autenticação excessivamente longo dá aos invasores mais tempo para comprometer as contas do usuário.

Explanation

Quanto mais tempo uma sessão fica aberta, maior a janela de oportunidade que um invasor tem para comprometer contas de usuário. Enquanto uma sessão permanece ativa, um invasor pode ser capaz de aplicar força bruta à senha de um usuário, quebrar a chave de criptografia sem fio de um usuário ou comandar uma sessão de um navegador aberto. Tempos limites de autenticação mais longos também podem impedir que a memória seja liberada e, eventualmente, resultar em uma denial of service se um número suficientemente grande de sessões for criado.

Exemplo 1: O exemplo a seguir mostra a ASP.NET MVC configurada com um tempo limite de autenticação de uma hora.


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

Se o atributo de tempo limite não for especificado, o tempo limite de autenticação será de 30 minutos.
