Metasploit Unleashed en Espanol (5.4/17)

Escaner Web WMAP

WMAP es un escaner de vulnerabilidad web con muchas caracteristicas, que fue originalmente creado a partir de una herramienta llamada SQLMap. Esta
herramienta ofrece la habilidad de tener un proxy y poder capturar paquetes para realizar analisis de vulnerabilidad. Primero tenemos que descargar un proxy que sea compatible y parchearlo con el Metasploit patch. Tambien tenga en cuenta, que si no lo ha hecho ya, instale rubygems y ruby-sqlite3 ya que es un requisito.

Compiled no errors.

Ahora que tenemos ratproxy parcheado y listo, tenemos que configurar el proxy para permitir que las comunicaciones pasen a traves del tunel de nuestro proxy y permitir Metasploit WMAP. Primero abre Firefox y sigue las opciones, en el menu Edit, Preferences, Advanced, Network, Setting, Manual proxy configuration, seleccione "Usar este proxy para todos los protocolos" y en el campo proxy HTTP, introducir localhost y establecer en el puerto 8080.

Una vez que este configurado, usaremos una serie de comandos, iremos a la pagina web, y de ultimo la atacaremos. Sigamos el proceso y veamos como
es. Primero necesitamos configurar y conectarnos a nuestra base de datos.

Ahora con todo funcionando, navegaremos al sitio web objetivo, Asegurate de estar un tiempo navegando por el sitio, y llenar la base de datos con suficiente informacion para que Metasploit pueda funcionar.

Una vez que terminemos de navegar por la pagina web objetivo, volvemos a la session de Metasploit y vemos lo que hemos capturado.

WMAP ahora utilizara los archivos de la base de datos que estaban apuntado a ratproxy y que se crearon con Metasploit, ahora empezaremos atacar al sitio web objetivo. Esto generalmente toma un tiempo, ya que hay una cantidad considerable de ataques en WMAP. Note que algunas comprobaciones no son confiables y pueden tomar mas tiempo para ser completadas. Para salir de un modulo auxiliar especifico, solo use "control-c" y seguira al siguiente modulo auxiliar.

Espere que todo el proceso haya finalizado y luego empieze con los comandos siguientes.

El informe devuelto a nosotros nos dice mucha informacion sobre la aplicacion web y posibles vulnerabilidades que se han identificado. Como pentesters, nos gustaria investigar cada uno e identificar si hay posibles metodos de ataques.

En el ejemplo, hay dos buenos resultados. El primero es WebDav donde podriamos saltarnos el inicio de sesion, el otro es el metodo PUT el cual puede que nos permita insertar codigo malicioso en la pagina web. WMAP es una buena adiccion al Metasploit Framework y permite tener un escaner de vulnerabilidad esencial intengrado en este gran framework.

Una cosa a mencionar sobre WMAP es que todavia se sigue trabajando en el. El sitio que se acaba de escanear tiene numerosos errores basados en inyecion de SQL y Cross-Site Scripting los cuales no fueron identificados. Solo tenga en cuenta al usarlo, y entienda las limitaciones actuales de WMAP.
