Detailsinfo

A vulnerability, which was classified as critical, has been found in Mail Mint Plugin up to 1.19.2 on WordPress. Affected by this issue is an unknown functionality of the component API Endpoint. The manipulation of the argument order-by/order-type/selectedCourses with an unknown input leads to a sql injection vulnerability. Using CWE to declare the problem leads to 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. Impacted is confidentiality, integrity, and availability. CVE summarizes:

The Mail Mint plugin for WordPress is vulnerable to blind SQL Injection via the 'forms', 'automation', 'email/templates', and 'contacts/import/tutorlms/map' API endpoints in all versions up to, and including, 1.19.2 . This is due to insufficient escaping on the user supplied 'order-by', 'order-type', and 'selectedCourses' parameters and lack of sufficient preparation on the existing SQL queries. This makes it possible for authenticated attackers, with administrator level access and above, to append additional SQL queries into already existing queries.

Additional levels of successful authentication are required for exploitation. Technical details are known, but there is no available exploit.
