- →Monitor POST requests to /?gf_page=upload endpoint with multipart/form-data containing executable file extensions (e.g., .php, .phtml) — no authentication is required by the vulnerable upload handler. ↗
- →Detect multipart POST requests to /?gf_page=upload where the 'name' field contains a double extension or executable extension (e.g., .phtml, .php) while the 'file' filename field uses a benign extension (e.g., .jpg) — a common bypass pattern used in exploitation. ↗
- →The gform_unique_id POST parameter is used for path traversal (value: ../../../); detect requests where this parameter contains directory traversal sequences. ↗
- ·The upload endpoint is entirely unauthenticated — there is no WordPress nonce, capability check, or session validation before files are accepted and moved to the upload directory. ↗
