File Upload Vulnerability to RCE and Root Access | Full Web Exploitation Walkthrough

One image upload form with no file type validation is all it takes to go from a photo upload to a full root shell. In this video we walk through a complete attack chain against a vulnerable web application: from recon to remote code execution through a malicious file upload, and finally to root through a sudo misconfiguration.

You will see the entire path an attacker takes: finding an exposed upload endpoint, exploiting the lack of file validation, planting a web shell, upgrading a raw connection into a full interactive shell, and escalating privileges once inside.

In this video:
Scanning the target and enumerating open ports
Discovering a hidden uploads directory with Gobuster
Exploiting an unrestricted file upload to plant a PHP web shell
Confirming remote code execution
Setting up a reverse shell and upgrading it to a full TTY
Hunting for credentials in configuration files
Escalating privileges through a sudo misconfiguration
Getting full root access

Key idea:
File upload forms are a common attack surface. When a server accepts a file without checking its extension, MIME type, or actual content, an attacker can upload executable code instead of an image and get remote code execution. Combined with a weak sudo rule deeper in the system, an initial foothold can quickly turn into full compromise.
