Use Burp Suite to intercept the request and rename test.jpg to shell.php after it passes the browser check. Content-Type Spoofing Method: The server checks the Content-Type header.
This comprehensive guide breaks down the full implementation, security best practices, and troubleshooting steps required to manage file uploads effectively. 1. Core Architecture of a Full File Upload Are you planning to store files on the
Verifying the browser-reported content type (e.g., image/jpeg ).
When intercepting the upload request using a proxy tool like Burp Suite, the attacker changes the Content-Type: application/x-php header to Content-Type: image/jpeg . If the application only checks the MIME-type, the file is accepted.
The Katsem system abstracts storage logic to support scalability.
