DVWA: File Upload (Low Security)

🔐 DVWA Vulnerability: File Upload (Low Security) | Complete Walkthrough In this video, I explain how to solve the DVWA File Upload vulnerability at the Low security level. This challenge demonstrates how improper file validation can allow an attacker to upload malicious files, potentially leading to Remote Code Execution (RCE). At the Low security level, DVWA does not properly validate file types, extensions, or content. This makes it possible to upload a malicious PHP file and execute commands directly on the server. I walk through: Understanding the vulnerable functionality Uploading a malicious file (e.g., PHP web shell) Accessing and executing the uploaded file Verifying successful exploitation This lab is a great starting point to understand unrestricted file upload vulnerabilities, which are commonly seen in real-world applications when proper security controls are missing. ⚠️ This demonstration is performed in a controlled lab environment (DVWA) for educational purposes only. Do not attempt these techniques on systems without proper authorization.
