[CVE-2023-27638][CWE-89] Improper neutralization of SQL parameters in module PrestaShop Custom Product Designer (tshirtecommerce) for PrestaShop

In the module Custom Product Designer (tshirtecommerce), an anonymous user can perform an SQL injection attack. The vulnerability is actively exploited by bots. As the module doesn’t seems to be maintained since 2019, it’s strongly suggested to remove it.

The following issues have been seen in the last version of the PrestaShop Custom Product Designer (tshirtecommerce) module for PrestaShop, published on July 24, 2019 (not fixed up to date) :

an HTTP request can be forged with a compromised product_id GET parameter in order to exploit an insecure parameter in front controller file designer.php, which could lead to a SQL injection.

and we also suspect that an HTTP request can be potentially forged with a compromised tshirtecommerce_design_cart_id GET parameter in order to exploit an insecure parameter in function hookActionCartSave and updateCustomizationTable, which could eventually lead to a SQL injection.

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.
