Infility Global <= 2.15.16 - Authenticated (Subscriber+) SQL Injection via 'orderby' Parameter

The Infility Global plugin for WordPress is vulnerable to SQL Injection via the 'orderby' and 'order' parameters in all versions up to, and including, 2.15.16. This is due to insufficient escaping on user supplied parameters and lack of sufficient preparation on the existing SQL query within the show_control_data::post_list() function, which is registered as an admin menu page with only the 'read' capability. This makes it possible for authenticated attackers, with Subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
