That's related to mod_security that your host must have installed.

There is a very good chance your host has installed a add-on for apache called mod_security.
Quote:
ModSecurityTM is an open source intrusion detection and prevention engine for web applications (or a web application firewall). Operating as an Apache Web server module or standalone, the purpose of ModSecurity is to increase web application security, protecting web applications from known and unknown attacks.
While mod_security can be a very powerful tool, misconfigured or overly strict rule sets can interfere with vBulletins Operation. Below for Apache users you can use an htaccess file and add a specific rule to disable mod_security.

Create or edit a text file named .htaccess for your main forum directory and add the following code:
Code:

<IfModule mod_security.c>
SecFilterEngine Off
SecFilterScanPOST Off
</IfModule>

Note, place this file in your main forum directory.
