Due to the huge spur in SQL injection attacks, Sana Ullah has done some great work on some .htaccess rules to protect against such injections. They have been committed to the ColdBox SVN, but we are also sharing here. Please note that all the rules are for ColdBox SES, so make sure to update accordingly.
