CTF | OverTheWire | Wargames | Natas | Level 12 | Bypassing Client-Side Control with Python
In this video, I dive deep into Natas Level 12 and explain the intricate steps to bypass client-side controls in the web application. First, I walk you through the PHP code of the web application to understand how it works and how we can bypass its restrictions. We’ll utilize Burp Suite for manipulating requests and bypassing client-side validation.
🔹 Techniques Covered:
✅ Understanding PHP Code – A detailed breakdown of the web application logic and its client-side controls
✅ Bypassing Client-Side Control – Using Burp Suite to intercept and manipulate HTTP requests
✅ Automating with Python – I show you how to fully automate the process using Python:
Downloading Web Pages
Using the re module to extract dynamically generated filenames
Uploading Files – I automate the file upload process to the web application
✅ Web Shell Exploitation – After uploading the file, I demonstrate how to use the uploaded file as a web shell, and implement a command-line interface to interact with the target system.
This video is perfect for those who want to learn how to automate exploitation and bypass restrictions using Burp Suite and Python, and leverage web shell exploitation in a real-world web application.
