CVE-2017-20198

CVSS

No CVSS.

T

he Marathon UI in DC/OS < 1.9.0 allows unauthenticated users to deploy arbitrary Docker containers. Due to improper restriction of volume mount configurations, attackers can deploy a container that mounts the host's root filesystem (/) with read/write privileges. When using a malicious Docker image, the attacker can write to /etc/cron.d/ on the host, achieving arbitrary code execution with root privileges. This impacts any system where the Docker daemon honors Marathon container configurations without policy enforcement.

Summary		(es) La interfaz de usuario de Marathon en DC/OS anterior a la versión 1.9.0 permite a usuarios no autenticados implementar contenedores Docker arbitrarios. Debido a la restricción incorrecta de las configuraciones de montaje de volúmenes, los atacantes pueden implementar un contenedor que monta el sistema de archivos root del host (/) con privilegios de lectura y escritura. Al usar una imagen de Docker maliciosa, el atacante puede escribir en /etc/cron.d/ del host, lo que permite la ejecución de código arbitrario con privilegios de root. Esto afecta a cualquier sistema donde el demonio de Docker respete las configuraciones de los contenedores de Marathon sin la aplicación de políticas.
