ASP.NET Misconfiguration: Weak Password Protection
Abstract
Armazenar uma senha em texto simples ou usando uma criptografia fraca pode resultar no comprometimento do sistema.
Explanation
Os aplicativos ASP.NET podem armazenar pares de nome de usuário e senha em elementos
As senhas armazenadas em texto simples ou usando um algoritmo de criptografia fraco são acessíveis a qualquer pessoa com acesso aos arquivos de configuração do aplicativo. Isso pode incluir a máquina onde o aplicativo está hospedado ou o repositório de código-fonte onde o aplicativo reside.
Exemplo 1: A seguinte entrada
O ASP.NET oferece suporte a senhas de credenciais armazenadas em três formatos, especificados pelo atributo
Embora um hash MD5 seja mais seguro do que texto simples, os pesquisadores descobriram ataques de força bruta contra o algoritmo de hash MD5. No momento, um hash SHA1 ainda fornece proteção razoável contra esses ataques.
<credentials>
no arquivo web.config
de um aplicativo ASP.NET, que suporta texto simples e formatos de senha MD5 e SHA1.As senhas armazenadas em texto simples ou usando um algoritmo de criptografia fraco são acessíveis a qualquer pessoa com acesso aos arquivos de configuração do aplicativo. Isso pode incluir a máquina onde o aplicativo está hospedado ou o repositório de código-fonte onde o aplicativo reside.
Exemplo 1: A seguinte entrada
web.config
armazena incorretamente suas senhas em texto simples.
<configuration>
<system.web>
<authentication>
<forms protection="All">
<credentials passwordFormat="Clear">
<user name="user1" password="my_password"/>
<user name="user2" password="my_password1"/>
</credentials>
</forms>
</authentication>
</system.web>
</configuration>
O ASP.NET oferece suporte a senhas de credenciais armazenadas em três formatos, especificados pelo atributo
passwordFormat
do elemento configuration/system.web/authentication/forms/credentials
. Os valores possíveis para este atributo são:Clear
- indica que a senha está armazenada em texto simples (menos seguro)MD5
- indica que o hash MD5 da senha está armazenadoSHA1
- indica que o hash SHA1 da senha está armazenado (mais seguro)Embora um hash MD5 seja mais seguro do que texto simples, os pesquisadores descobriram ataques de força bruta contra o algoritmo de hash MD5. No momento, um hash SHA1 ainda fornece proteção razoável contra esses ataques.
