The TableOn – WordPress Posts Table Filterable plugin for WordPress is vulnerable to blind SQL Injection via the `filter_data[comment_count]` parameter of the public `tableon_get_table_data` AJAX action in all versions up to, and including, 1.0.5.1. This is due to insufficient escaping on the user-supplied parameter and lack of sufficient preparation on the existing SQL query — the value is split on `:` and both halves are interpolated directly into a `posts_where` SQL clause without `intval()` casting or `$wpdb->prepare()`. This makes it possible for unauthenticated attackers to append additional SQL queries into the already-existing query that can be used to extract sensitive information from the database (researcher demonstrated extraction of database(), wp_users.user_login, and wp_users.user_pass).
