Remote File Inclusion

What It Means

This request attempted to trick your application into downloading and executing an external resource — typically a backdoor script that would give the attacker control of your application.

Why It Matters

Remote file inclusion (RFI) attacks exploit applications that dynamically include files based on user input. If successful, the attacker can load their own malicious code from an external server and execute it within your application’s context, leading to full server compromise.

Common Triggers

Requests containing external URLs in parameters that normally reference local files, or attempts to use language-specific include functions with remote paths. These are automated scans probing for inclusion vulnerabilities.

What To Do

RFI blocks are always legitimate threat detection. These blocks should remain in place. No action is typically required.
