The netgear_r7000_cgibin_exec module exploits a command injection vulnerability in Netgear R7000 and R6400 router firmware version `1.0.7.2_1.1.93` and possibly earlier. The vulnerability is found in the `/cgi-bin/` folder of the router. A manual injection would look like so: `http://<RouterIP>/cgi-bin/;echo$IFS"cowsay"`. This will echo 'cowsay' on the router.

The vulnerability is found in the `/cgi-bin/` folder of the router. A manual injection would look like so: `http://<RouterIP>/cgi-bin/;echo$IFS"cowsay"`. This will echo 'cowsay' on the router. A fairly useful manual command injection is like so: `http://<RouterIP>/cgi-bin/;telnetd$IFS-p$IFS'45'` will open telnet on port 45.

## Options
**PAYLOAD**
The valid payloads are `cmd/unix` payloads _only_, as this is a command execution module
The valid payloads are `mettle` payloads _only_. The payload uses the `wget` flavor and pipes the downloaded binary to `sh`
