Reverse Shell on a Web Server

In this lab, you will explore the consequences of poor validation in file upload forms within a vulnerable web server. Your objective is to interact with the exposed functionality, analyze its behavior, and assess whether it is possible to establish a remote session with the system.

This exercise will help you understand how improper implementation in file handling can seriously compromise a server's security.

🌱 How to Start This Lab

Follow these instructions to get started:

1. Download the virtual machine from this link:

1. Import the machine into your preferred virtualization software like VirtualBox.
2. To perform this lab, you will need an additional virtual machine to act as your attacking environment. This machine must have cybersecurity tools. We recommend using Kali Linux.
   • Download the pre-built Kali Linux virtual machine image from its official website. Use the "Virtual Machines" option from this link.
3. Once the machine is started, you can begin the lab!

Remember: You are in a controlled environment for educational purposes. Ethical knowledge is your best tool. Observe, explore, and learn to identify insecure configurations.

Happy hacking!
