Executive brief
The WP Fast Total Search plugin for WordPress, which provides advanced search capabilities for websites, contains a security flaw that allows unauthorized individuals to access private database information. By sending a specially crafted search request, an attacker can bypass security measures to view sensitive data stored on the site's server. This could lead to the exposure of user details or other confidential business information.
Technical details
The WP Fast Total Search – The Power of Indexed Search plugin for WordPress is vulnerable to generic SQL Injection via the 'form_data[s]' parameter in all versions up to, and including, 1.80.280. This vulnerability stems from insufficient escaping of user-supplied input and a lack of proper SQL query preparation using WordPress's wpdb::prepare() or similar methods. An unauthenticated remote attacker can exploit this by submitting malicious SQL commands through the search form, enabling them to append additional queries to existing database calls. This can be leveraged to extract sensitive information, such as user credentials or site configuration data, from the WordPress database.
