Command Injection Walkthrough: Extract Database Password from database.php | Hackviser Question

In this video, we solve a real Command Injection question from the Hackviser platform and walk through the complete exploitation process step by step in a beginner-friendly way.

This Hackviser labs question focuses on identifying a command injection vulnerability in a DNS lookup web application and using it to extract sensitive data from a server. We demonstrate how improper input filtering can be bypassed using simple techniques and how attackers can read critical files like database.php to retrieve database credentials.

You will learn how command injection works in real-world scenarios, how blacklist-based filters fail, and how to use common bypass techniques to execute system commands successfully.

This video is especially useful for beginners in ethical hacking, penetration testing, and bug bounty hunting who are practicing Hackviser labs questions.

Topics covered in this video:

Understanding command injection vulnerability
Identifying injection points in web applications
Testing for command execution
Bypassing blacklist filters using obfuscation techniques
Using payloads to list files on the server
Reading sensitive files like database.php
Extracting database password from application configuration

This walkthrough is part of hands-on practice on the Hackviser platform and is intended for educational purposes only.

If you are learning web security or preparing for penetration testing, practicing challenges like this from Hackviser labs will significantly improve your skills.
