Improper neutralization of SQL parameter in Helloshop - Tracking Center - Parcel tracking 80 carriers module for PrestaShop

In the module “Tracking Center - Parcel tracking 80 carriers” (deliveryorderautoupdate) up to version 2.8.2 from Helloshop for PrestaShop, a guest can perform SQL injection in affected versions.

Ajax script ajax_email.php, all scripts in directory webservices/ and the method DeliveryorderautoupdateOrdersModuleFrontController::initContent() has sensitive SQL calls that can be executed with a trivial http call and exploited to forge a SQL injection.

WARNING : One of exploits (against ajax_email.php) is actively used to deploy a webskimmer to massively steal credit cards.

Note : the author has deleted from his module one of the files (ajax_email.php) which have been suffering from critical vulnerabilities for years, BUT did not set them to be “auto-deleted” during upgrades. Therefore, there are likely merchants out there with older versions who have updated their modules, thinking they are safe. However, there is nothing safe about that, since past upgrades did not auto-delete the implicated files. To ensure everyone has a “safe version”, we decided to mark all versions up to 2.8.1 as impacted by this issue.

DANGER : Patch provided are partial - since there is more than 100 critical issues inside the directory webservices/, we do not provide patch - put the directory under IP restriction without delay or upgrade the module.

One of exploits 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.
