Reino: API Abuse
Uma API é um contrato entre quem chama e o que se chama. As formas mais comuns de abuso de API ocorrem quando o responsável pela chamada não respeita sua parte do contrato. Por exemplo, se um programa não chama chdir() após chamar chroot(), ele viola o contrato que especifica como alterar o diretório raiz ativo de forma segura. Outro bom exemplo de abuso de biblioteca é esperar que o elemento chamado retorne informações confiáveis de DNS ao responsável pela chamada. Nesse caso, o responsável pela chamada abusa a API do elemento chamado ao fazer certas suposições sobre seu comportamento (isto é, que o valor de retorno pode ser usado para fins de autenticação). A outra parte também pode violar o contrato entre quem chama e o que se chama. Por exemplo, se um programador definir SecureRandom como subclasse e retornar um valor não aleatório, o contrato será violado.
ASP.NET Middleware Out of Order: Insufficient Logging
Abstract
O aplicativo especifica o middleware de registro em log do ASP.NET Core incorretamente.
Explanation
O middleware ASP.NET Core que não é adicionado ao pipeline de middleware na ordem correta não funcionará conforme o esperado, deixando um aplicativo aberto a vários problemas de segurança.
Exemplo 1: O método
Exemplo 1: O método
UseHttpLogging() adiciona middleware de registro em log HTTP ao pipeline de middleware que permite que os componentes de middleware sejam registrados em log. Quando especificado na ordem errada, conforme mostrado, nenhum middleware adicionado ao pipeline antes da chamada para UseHttpLogging() será registrado em log.Exemplo 2: O método
...
var builder = WebApplication.CreateBuilder(...);
var app = builder.Build(...);
app.UseStaticFiles();
app.UseRouting();
app.UseSession();
app.UseAuthentication();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
...
}
app.UseHttpLogging();
...
UseWC3Logging() adiciona o middleware de registro em log do W3C ao pipeline de middleware que permite que os componentes de middleware sejam registrados em log. Quando especificado na ordem errada, conforme mostrado, nenhum middleware adicionado ao pipeline antes da chamada para UseWC3Logging() será registrado em log.
...
var builder = WebApplication.CreateBuilder(...);
var app = builder.Build(...);
app.UseStaticFiles();
app.UseRouting();
app.UseSession();
app.UseAuthentication();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
...
}
app.UseWC3Logging();
...
