I. Description

ISPConfig is a fully-fledged solution for multi-domain Internet hosts, 
covering email,
FTP, database and Web services through a nifty control panel. Throw in 
security,
customer management and a billing solution, and it gets pretty attractive.

=======================================================================================

II. Synopsis

There is a remote file inclusion vulnerability that allows for remote 
command execution
in the /lib/session.inc.php file.  The bug is here:

include($go_info["server"]["classes_root"] . 
$go_info["server"]["dir_trenner"]
."ispconfig_template.lib.php");

the $go_info["server"]["classes_root"] variable is not set prior to 
being used in the
include() function.  The vendor and support team have been contacted.
