# Exploit Title: ZTE and TP-Link RomPager DoS Exploit
# Date: 10-05-2014
# Server Version: RomPager/4.07 UPnP/1.0
# Tested Routers: ZTE ZXV10 W300
# TP-Link TD-W8901G
# TP-Link TD-W8101G
# TP-Link TD-8840G
# Firmware: FwVer:3.11.2.175_TC3086 HwVer:T14.F7_5.0
# Tested on: Kali Linux x86
#
# Notes: Please note this exploit may contain errors, and
# is provided "as it is". There is no guarantee
# that it will work on your target router(s), as
# the code may have to be adapted.
# This is to avoid script kiddie abuse as well.
