Module 5: OWASP Top 10 File Inclusion Attacks (LFI vs RFI) Step-by-Step Training
Master File Inclusion Vulnerabilities (LFI & RFI) in this deep-dive cybersecurity training!
File Inclusion is often underestimated and dismissed as "just a file read". However, when dynamic file inclusion mechanisms lack proper input validation, they can quickly escalate to sensitive data exposure or even full Remote Code Execution (RCE).
In this video, we move beyond the surface level to explore how attackers use Local File Inclusion (LFI) to traverse directories and read system files like /etc/passwd. We also contrast this with Remote File Inclusion (RFI), where attackers inject malicious external scripts to hijack web servers.
What You’ll Learn:
The Mechanics of Exploitation: Step-by-step walkthrough of Directory Traversal using ../ sequences.
Advanced Bypass Techniques: How to circumvent filters using Null Byte Injection (%00), Path Truncation, and PHP Wrappers like php://filter and zip://.
Attack Escalation: Turning an LFI vulnerability into a full system compromise through Log Poisoning.
Real-World Context: A look at the famous TimThumb vulnerability that affected thousands of sites.
Modern Defenses: How to secure your code using Whitelisting (Allow Lists), absolute paths, and server-level hardening like disabling allow_url_include in PHP.
