path/show_part_label.php↗

path/data/media/labels/↗

→Monitor for multipart POST file uploads to show_part_label.php where the uploaded file has a .phtml extension (or other executable PHP extensions) in the logo_file field — this is the delivery mechanism for the webshell. ↗
→Alert on any new .phtml (or .php) files appearing under the /data/media/labels/ directory of a Part-DB installation, as this is where the exploit drops the webshell after upload. ↗
→Detect HTTP GET/POST requests to /data/media/labels/*.phtml — successful exploitation results in direct web-accessible shell execution at this path. ↗

·The exploit targets Part-DB versions prior to 0.5.11; the vulnerable endpoint show_part_label.php accepts arbitrary file uploads without validating the file extension, allowing .phtml webshells to be stored in a web-accessible directory. ↗
·The exploit script hard-codes a default sub-path of /Part-DB-0.5.10 on the web host, suggesting default/unmodified installations are the primary target; detections should also cover non-default install paths. ↗
