Description

This module exploits a heap buffer overflow in the genie.cgi?backup.cgi
page of Netgear R7000 routers running firmware version 1.0.11.116.
Successful exploitation results in unauthenticated attackers gaining
code execution as the root user.

The exploit utilizes these privileges to enable the telnet server
which allows attackers to connect to the target and execute commands
as the admin user from within a BusyBox shell. Users can connect to
this telnet server by running the command "telnet *target IP*".
