Understanding XXE Attacks: Theory & File Upload Exploitation

🔐 In this video, we dive into XML External Entity (XXE) attacks and how they can be leveraged through file upload vulnerabilities in web applications.

You’ll learn:

What XXE is and how it works behind the scenes
How attackers abuse XML parsers and external entities
Why file upload features can become a serious security risk
A step-by-step walkthrough of a theoretical XXE exploit using a real-world lab scenario
How sensitive files (like /etc/passwd) could be exposed if a system is vulnerable
Practical mitigation techniques, including disabling DTDs and external entities
We’ll also explore how improper file validation can lead to bypassing upload restrictions, making this vulnerability even more impactful.

⚠️ Note: This demonstration is conducted in a controlled lab environment for educational purposes only.

If you're into web application security, penetration testing, or bug bounty hunting, this is a must-watch.
