A web interface that turns the mundane task of file uploading into a shooting gallery game. Files act as "ammunition," and the upload target acts as the "bullseye."

Using double extensions (e.g., shell.php.jpg ) or null byte injections.

The primary goal of many "gunner" tools is to bypass filters and upload a server-side script (e.g., .php , .jsp , .asp ). If the server executes the file, the attacker gains a foothold to take over the entire system.

Strip metadata and re-process images (e.g., using a library to re-save a JPEG) to destroy embedded payloads.

Critical Security Measures To keep your project secure, follow these principles from the OWASP File Upload Cheat Sheet : Validate File Types: Never trust the client-provided extension; verify the actual file content type. Rename Files: Generate unique, random filenames on the server to prevent directory traversal attacks or overwriting. Set Limits: Enforce strict file size and filename length limits to prevent DoS attacks. Storage: Store uploaded files outside the web root directory whenever possible. owasp +1 4. Troubleshooting Common Issues Permitted File Types: If you get "Not allowed to upload this file type," check your server configuration (e.g.,

const upload = multer( storage: storage ); These projects typically automate methods like: The primary

Testing if the system crashes or becomes unresponsive when "gunned" with massive files or a high volume of concurrent uploads that overwhelm storage or database limits. Industry-Standard Mitigation Strategies
