WP Job Portal <= 2.2.2 - Authenticated (Admin+) SQL Injection via wpjobportal_deactivate()

The WP Job Portal – A Complete Recruitment System for Company or Job Board website plugin for WordPress is vulnerable to SQL Injection via the 'page_id' parameter of the wpjobportal_deactivate() function in all versions up to, and including, 2.2.2 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. 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.
