Description

This module exploits an authentication bypass vulnerability in the infosvr service running on UDP port 9999 on various ASUS routers to execute arbitrary commands as root. This module launches the BusyBox Telnet daemon on the port specified in the TelnetPort option to gain an interactive remote shell. This module was tested successfully on an ASUS RT-N12E with firmware version 2.0.0.35. Numerous ASUS models are reportedly affected, but untested.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
