Frequently asked questions

What is the op'art_limit_quantity module for PrestaShop?

It is an add-on module for the PrestaShop e-commerce platform designed to manage product inventory constraints. Owners use it to set limits on the quantities of items customers can purchase at one time. Because it handles front-end interactions directly on the storefront, it is typically installed on web servers to provide these shopping features to visitors.

How does CVE-2023-36263 result in a SQL injection?

This vulnerability falls under the Improper Neutralization of Special Elements used in an SQL Command (CWE-89) weakness class. It occurs because the module's code fails to properly sanitize user-supplied data before incorporating it into database queries. Consequently, an attacker can submit malicious database commands through the application that the system then executes, potentially allowing unauthorized access or manipulation of shop data.

Do I need to be logged in to trigger this vulnerability?

No, authentication is not required to trigger this bug. The vulnerability exists within a component that processes web requests directly from the front end. A simple, specially crafted HTTP request sent to the affected module's interface is sufficient to initiate the exploit. Normal background site activity that does not interact with this specific module's alert message function will not trigger the flaw.

Why should I care about this vulnerability based on Halo Surface Signal?

Halo Surface Signal classifies this vulnerability as external because the affected module is designed for customer-facing storefront interactions. Since it resides on public-facing web servers to enable core e-commerce functionality, the module is easily reachable from the internet. If your site uses this module, it is exposed to potential unauthorized access attempts originating from outside your internal network.

How should I respond if I am running this technology?

The immediate step is to verify if your PrestaShop installation currently has the op'art_limit_quantity module enabled and check the version number. If you are running any version earlier than 1.4.6, you are affected. Identify the team responsible for managing your e-commerce platform and prioritize updating the module to the latest version to neutralize the SQL injection risk.
