Remote File Inclusion (RFI) Scanner
Tests for remote file inclusion allowing execution of external malicious scripts.
What is Remote File Inclusion (RFI)?
Remote File Inclusion (RFI) allows attackers to include files from external servers, typically by manipulating a URL parameter. When the application includes this remote file, any code within it executes on the server, giving attackers immediate remote code execution capabilities.
Why is This Important?
RFI provides instant remote code execution—attackers host a malicious script on their server and make your application execute it. This leads to complete server compromise, data theft, malware installation, and lateral movement to other systems.
How It Works
1. Web Crawling
Intelligent crawling discovers all endpoints, forms, parameters, and dynamic content across your web application.
2. Payload Injection
AI-powered payloads test each input vector for web vulnerabilities with context-aware attack patterns.
3. Response Analysis
Advanced analysis detects vulnerability signatures in responses, confirming exploitability with proof-of-concept.

Frequently Asked Questions
How common is RFI compared to LFI?
RFI is less common because many configurations disable remote file inclusion by default (PHP's allow_url_include). However, when present, it's immediately critical.
What PHP settings affect RFI?
allow_url_include must be enabled for RFI to work in PHP. allow_url_fopen allows including remote files with functions like file_get_contents but doesn't enable code execution directly.
Can RFI work with HTTPS URLs?
Yes, if the server has appropriate SSL libraries. Attackers can host malicious files on HTTPS servers to bypass some network-level protections.
What's the first thing attackers do after RFI?
Typically upload a web shell for persistent access, then enumerate the system, escalate privileges, dump databases, and look for lateral movement opportunities.
