Task: Achieve RCE on a PHP application with LFI via include() with .php extension appended. Solution: Use php://filter/convert.base64-encode to read source code and leak credentials, then use php_filter_chain_generator to craft an iconv filter chain that injects arbitrary PHP code through the LFI without file upload.
