WP Coder – add custom html, css and js code <= 2.5.3 - Authenticated (Admin+) SQL Injection

Vulnerability Description

The WP Coder – add custom html, css and js code plugin for WordPress is vulnerable to time-based SQL Injection via the ‘id’ parameter in versions up to, and including, 2.5.3 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 administrative privileges to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
