Another method (similar to previous) is to make your own Plugin, its very simple we have the code for you here.
Simply open a new PHP file using a simple note or text editor and paste the following code inside:
<?php /* Plugin Name: Block Bad Queries Description: Protect WordPress Against Malicious URL Requests */ global $user_ID; if($user_ID) { if(!current_user_can('level_10')) { if (strlen($_SERVER['REQUEST_URI']) > 255 ||
strpos($_SERVER['REQUEST_URI'], "eval(") ||
strpos($_SERVER['REQUEST_URI'], "CONCAT") ||
strpos($_SERVER['REQUEST_URI'], "UNION SELECT") ||
strpos($_SERVER['REQUEST_URI'], "base64")) {
@header("HTTP/1.1 414 Request-URI Too Long");
@header("Status: 414 Request-URI Too Long");
@header("Connection: Close");
@exit;
}
}
} ?>
Save this file as miltonmarketingprotect.php and upload it in your plugin directory /wp-content/plugins/ and your done.
This script will check for long strings as well as base64 code which was in the last attack and the eval ( code which could be a threat in the future.) 🙂
Once activated, this plugin will silently and effectively close any connections for these sorts of injection-type attacks.
