  • Weakness: CWE-918
  • Severity: critical (9.1)


In the Product Designer module from Tunis Soft for PrestaShop, an improper validation of url parameter in the method ProductDesignerPixabayModuleFrontController::postProcess can be executed via a trivial HTTP call to forge Server-Side Request.

This vulnerability can be exploited to initiate a HTTP request and get the return, for instance, use the vulnerable website as proxy to attack others websites, exfiltrate data in files under IP restriction or perform a path traversal attack.

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.
