  • Disclosed: 18.06.2024
  • Updated: 11.10.2026 10:22

In the module “Help Desk - Customer Support Management System” (helpdesk) up to version 2.4.0 from FME Modules for PrestaShop, a customer can upload .php files.

Methods HelpdeskHelpdeskModuleFrontController::submitTicket() and HelpdeskHelpdeskModuleFrontController::replyTicket() allow upload of .php files on a predictable path for connected customers, it will lead to a critical vulnerability CWE-94.

This exploit uses a PrestaShop front controller and most attackers can conceal the module controller’s path during the exploit, so you will never know within your conventional frontend logs that it exploits this vulnerability. You will only see “POST /” inside your conventional frontend logs. Activating the AuditEngine of mod_security (or similar) is the only way to get data to confirm this exploit.
