DVWA: File Inclusion (Low Security)

In this video, I demonstrate how to exploit the File Inclusion vulnerability in Damn Vulnerable Web Application (DVWA) when the security level is set to Low. File Inclusion vulnerabilities occur when a web application dynamically includes files without properly validating user input. Attackers can exploit this weakness to read sensitive files from the server or execute malicious code. This type of vulnerability is commonly categorized under Local File Inclusion (LFI) and can lead to serious security issues such as information disclosure or even remote code execution in some cases using Remote File Inclusion (RFI). During this walkthrough, we analyze the vulnerable functionality in DVWA and demonstrate how an attacker can manipulate the page parameter to include arbitrary files from the server. As part of the demonstration, we retrieve sensitive system information such as the /etc/passwd file to confirm successful exploitation. Topics covered in this video: Understanding File Inclusion vulnerabilities Identifying the vulnerable parameter Exploiting Local File Inclusion (LFI) and Remote File Inclusion (RFI) in DVWA Retrieving sensitive files from the server Damn Vulnerable Web Application is widely used for learning web application security and practicing real-world vulnerabilities in a safe environment. This tutorial is useful for beginners in application security, penetration testers, bug bounty hunters, and students preparing for web security certifications. ⚠️ This demonstration is performed in a controlled lab environment for educational purposes only.
