The Booking Calendar WpDevArt plugin is vulnerable to time-based, blind SQL injection via the id parameter in the “wpdevartbookingcalendar” shortcode in versions up to, and including, 3.2.19 due to insufficient escaping on the user-supplied parameter and lack of sufficient preparation on the existing SQL query. The vulnerability requires the “deleteprevdate” theme option being enabled. This makes it possible for authenticated attackers, with contributor-level access or above, to append additional SQL queries into already existing query that can be used to extract sensitive information such as passwords from the database.
