TERN es proyecto open source de VMware que realiza una inspección de metadatos de los paquetes instalados en una imagen de contenedor. La herramienta genera un informe proporcionando una explicación detallada, capa por capa, de los diversos componentes de software que tenga la imagen del container. Si se proporciona un Dockerfile, el informe indica las líneas de Dockerfile correspondientes a cada una de las capas del sistema de archivos. El proyecto es open source de VMware. Enlace a el proyecto en github TERN

En Docker Hub hay millones de imágenes de Docker y no todas tienen una validación de imagen oficial o publicador verificado. Por ello, queda en tu responsabilidad el uso de una imagen, sin saber que contiene exáctamente y si contiene alguna vulnerabilidad software.

Además TERN se interga con 2 extensiones muy interesantes:

  • Scancode-toolkit: es una herramienta de análisis que detecta licencias, derechos de autor, manifiestos de paquetes y dependencias directas tanto en el código fuente como en archivos binarios. Enalce al proyecto Scancode-toolkit
  • cve-bin-tool es una herramienta de línea de comandos que busca una serie de componentes vulnerables comunes (node, nginx, openssl, openvpn, openssh, systemd, mariadb, samba, postgresql, libpng, libxml2, expat y algunos otros) para hacerle saber si su sistema incluye bibliotecas comunes con vulnerabilidades conocidas. El proyecto de es Intel ®, información aquí cve-bin-tool

Realizo una instalación sobre CentOS 7 de TERN con las 2 extensiones

Con cve-bin-tool se reuqieren las siguientes dependencias:

yum install centos-release-scl
yum install rh-python36
scl enable rh-python36 bash
yum install epel-release
yum install git attr unzip cabextract

Creamos un entorno virtual en Python:

python -m venv scanenv
cd scanenv
source bin/activate

Isntalamos las aplicaciones:

pip install --upgrade pip 
pip install tern cve-bin-tool

Para instalar Scancode junto con cve-bin-tool, realizar los pasos anteriores y añadir la siguinte paquetería:

yum install gcc zlib bzip2-libs xz-libs libxml2-devel libxslt-devel rh-python36-python-devel.x86_64
pip install tern cve-bin-tool scancode-toolkit[full]

 

Ejecutamos TERN con una imagen de ubuntu al azar de Docker Hub:

tern report -i imagen:latest -o ubuntutest3.txt

(no especifico el nombre de la imagen)

TERN ha generado el siguiente contenido en el fichero ubuntutest3.txt
