Rename wp-login.php to anything you want <= 2.0.1 - Unauthenticated SQL Injection via 'log' (Username) Parameter
The Rename wp-login.php to anything you want plugin for WordPress is vulnerable to time-based SQL Injection via 'log' (Username) Parameter in all versions up to, and including, 2.0.1 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. WordPress core applies wp_unslash() to the 'log' POST value before dispatching the wp_login_failed action, stripping magic-quotes backslash escaping and allowing a raw single quote to reach the plugin's handler unimpeded.
