En esta práctica vamos a realizar una auditoría de seguridad sobre nuestra instalación de WordPress con la que hemos estado trabajando en las prácticas anteriores.
La herramienta que vamos a utilizar para realizar la auditoría de
nuestro sitio web WordPress es wpscan.
Vamos a utilizar una imagen Docker que ya contiene la utilidad WPScan. El archivo Dockerfile que se ha utilizado para crear la imagen está disponible en el repositorio GitHub del proyecto.
La imagen de WPScan está disponible en Docker Hub:
Para consultar todas las acciones que podemos realizar con ÑWPScan podemos consultar la ayuda ejecutando el siguiente comando:
La salida que obtendremos será similar a esta:

--stealthy Alias for --random-user-agent --detection-mode passive --plugins-version-detection passiveA continuación vamos a ver algunos ejemplos básicos de uso.
Ejemplo 1
Para obtener la lista de plugins instalados en nuestro sitio WordPress podemos ejecutar:
Donde 192.168.22.20 será la dirección IP de la máquina donde hemos realizado la instalación de WordPress.
Ejemplo 2
Para realizar un escaneo completo de un sitio WordPress podemos ejecutar:
Donde 192.168.22.20 será la dirección IP de la máquina donde hemos realizado la instalación de WordPress.
Ejemplo 3
En este ejemplo haremos uso de la API de WPScan que nos permite detectar vulnerabilidades haciendo uso de su base de datos de vulnerabilidades.
Para poder hacer uso del servicio de la API de WPScan,es necesario registrarse en su web y obtener un TOKEN.
docker run -it --rm wpscanteam/wpscan --url http://192.168.22.20 --api-token 8pIlWnF2dxbgfvyQfDAUaV3T3iafo0uO1K8OPr2KKRMDonde 192.168.22.20 será la dirección IP de nuestro balanceador web.
A continuación se muestran varias referencias relacionadas con la seguridad de WordPress.
