Dockerfile Misconfiguration: Privileged Port

Docker

Abstract

El Dockerfile abre puertos de contenedor inferiores a 1024.

Explanation

De forma predeterminada, el docker permite enlazar puertos privilegiados a un contenedor y, si el usuario no declara un puerto, el docker asigna el puerto del contenedor a uno disponible en el rango 49153-65535. En muchos casos, es necesario abrir ciertos puertos para ejecutar servicios y, con el tiempo, la cantidad de puertos abiertos puede aumentar. Los puertos abiertos aumentan la superficie de ataque, especialmente para los servicios que se ejecutan con mayores privilegios. Asegúrese de abrir solo los puertos necesarios para ese servicio específico. Cuando los servicios no requieran mayores privilegios, ejecútelos en un puerto no incluido en el rango de puertos privilegiados.
