Frequently Asked Questions

Find Quick Answers

What is a CGI script?

CGI (Common Gateway Interface) is a standard protocol for web servers to execute programs like scripts (e.g., Perl, Python) and generate dynamic web content. CGI scripts typically have extensions like .cgi or .pl.

What does this tool check?

The tool checks if the CGI script at the provided URL is accessible, analyzes the HTTP response status and headers, measures response time, and looks for common security indicators like server information leaks or error messages.

Do I need to install anything?

No, this is a completely client-side tool that runs in your browser. It sends HTTP requests directly from your browser to the target URL without requiring any server-side processing.

Can I check local or private URLs?

No, due to browser security restrictions (CORS), you can only check publicly accessible URLs. The tool cannot access URLs on localhost or private networks unless they are exposed to the internet.

Is this tool safe to use?

Yes, the tool only sends HTTP GET requests to the provided URL, similar to what a regular browser does. It does not modify any data or perform malicious actions. However, always ensure you have permission to test the target URL.
