Detailsinfo

A vulnerability, which was classified as critical, was found in Quentn Quentn WP Plugin up to 1.2.12 on WordPress. This affects the function get_user_access of the component Parameter Handler. The manipulation of the argument qntn_wp_access with an unknown input leads to a sql injection vulnerability. CWE is classifying the issue as 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. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The Quentn WP plugin for WordPress is vulnerable to SQL Injection via the 'qntn_wp_access' cookie in all versions up to, and including, 1.2.12. This is due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query in the `get_user_access()` method. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
