Detailsinfo

A vulnerability has been found in wpmanageninja FluentCart Plugin up to 1.7.0 and classified as problematic. Affected by this vulnerability is an unknown functionality. The manipulation of the argument products[*].variants[*] with an unknown input leads to a sql injection vulnerability. The CWE definition for the vulnerability is CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

The FluentCart A New Era of eCommerce – Faster, Lighter, and Simpler plugin for WordPress is vulnerable to generic SQL Injection via the 'products[*].variants[*].<attacker-chosen key>' parameter in all versions up to, and including, 1.7.0 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with custom-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. On FluentCart Pro installs, non-administrator users assigned the Manager shop role also hold the products/edit permission and are therefore able to exploit this vulnerability without administrator-level access.
