Reino: API Abuse

Un API es un contrato entre un autor de llamada y un receptor de llamada. Las formas de abuso de API más comunes los produce el autor de llamada cuando no consigue atender su fin de este contrato. Por ejemplo, si un programa no consigue llamar chdir() después de llamar chroot(), se viola el contrato que especifica cómo cambiar el directorio de origen activo de una forma segura. Otro buen ejemplo de un abuso de manual es esperar que el receptor devuelva una información de DNS de confianza al autor de llamada. En este caso, el autor de llamada abusa el API del receptor haciendo determinadas suposiciones sobre su comportamiento (que el valor de retorno se puede usar con fines de autenticación). También se puede violar el contrato entre el autor de llamada y el receptor desde el otro lado. Por ejemplo, si un codificador envía SecureRandom y devuelve un valor no aleatorio, se viola el contrato.

ASP.NET Middleware Out of Order: Insufficient Logging

Abstract
La aplicación especifica incorrectamente el middleware de registro de ASP.NET Core.
Explanation
El middleware ASP.NET Core que no se agrega a la canalización de middleware en el orden correcto no funcionará según lo previsto, dejando la aplicación expuesta a una variedad de problemas de seguridad.

Ejemplo 1: El método UseHttpLogging() agrega middleware de registro HTTP a la canalización de middleware que permite que los componentes de middleware se registren. Cuando se especifica en el orden incorrecto, como se muestra, no se agrega ningún middleware a la canalización antes de que se registre la llamada a UseHttpLogging().


...
var builder = WebApplication.CreateBuilder(...);
var app = builder.Build(...);
app.UseStaticFiles();
app.UseRouting();
app.UseSession();
app.UseAuthentication();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
    ...
}

app.UseHttpLogging();
...
Ejemplo 2: El método UseWC3Logging() agrega el middleware de registro W3C a la canalización de middleware que permite que los componentes de middleware se registren. Cuando se especifica en el orden incorrecto, como se muestra, no se agrega ningún middleware a la canalización antes de que se registre la llamada a UseWC3Logging().


...
var builder = WebApplication.CreateBuilder(...);
var app = builder.Build(...);
app.UseStaticFiles();
app.UseRouting();
app.UseSession();
app.UseAuthentication();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
    ...
}

app.UseWC3Logging();
...
