LearnPress <= 4.4.4 — Authenticated (Administrator+) SQL Injection via 'orderby' Parameter

Am I affected?

• Check your version: in wp-admin go to Plugins → Installed Plugins and read the version under LearnPress – WordPress LMS Plugin for Create and Sell Online Courses.
• No admin access? Run a passive check of your site. It reads public files only.

What to do

1. Update to version 4.4.5, or a newer patched version
2. Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
3. Watch LearnPress – WordPress LMS Plugin for Create and Sell Online Courses to get an email when the next vulnerability is published.

Advisory

Source description from Wordfence Intelligence, credited to Wordfence PRISM.

The LearnPress plugin for WordPress is vulnerable to SQL Injection via the 'orderby' parameter of the export_order_csv AJAX action in versions up to, and including, 4.4.4. This is due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query in the LP_Order::handle_params_query_list_orders() and DataBase::execute() functions — only the literal values 'date' and 'title' are normalized, while any other attacker-controlled string is assigned directly to the filter's order_by property and concatenated into the ORDER BY clause without $wpdb->prepare() or an identifier whitelist. This makes it possible for authenticated attackers, with administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
