commandPOST /wp-admin/admin.php?page=html2wp-settings with multipart/form-data field name="local_importing[]" and a .php filename↗
- →Unauthenticated POST to /wp-admin/admin.php?page=html2wp-settings with a multipart file upload (field: local_importing[]) containing a PHP file should trigger a 302 redirect; the uploaded file is then accessible at /wp-content/uploads/html2wp/<filename>.php returning HTTP 200. ↗
- →Monitor for multipart/form-data POST requests to the html2wp-settings admin page that include a PHP (or other executable) file in the local_importing[] field, especially from unauthenticated or low-privilege sessions (no CSRF token required). ↗
- →Alert on new PHP files appearing under the wp-content/uploads/html2wp/ directory, as this is the drop location for files uploaded via exploitation of this vulnerability. ↗
- →The multipart boundary used in the proof-of-concept is ---------------------------7816508136577551742878603990; while not a reliable long-term signature, it may appear in active exploit traffic. ↗
- ·The vulnerability affects HTML2WP plugin versions up to and including 1.0.0 only; patched or removed installations are not affected. ↗
- ·The Nuclei template uses a randomised filename ({{randstr}}.php) for the uploaded webshell, so the exact filename will vary per exploit attempt and cannot be used as a static IOC. ↗
