iDefense Security Advisory 04.28.09
Apr 28, 2009
Symantec System Center is an MMC (Microsoft Management Console) snap-in
that allows an administrator to remotely manage Symantec products. The
Symantec System Center comes bundled with several Symantec products,
including Symantec Client Security and Symantec AntiVirus. It contains
an optional component called the Alert Management System Console. This
component starts a service (Intel File Transfer) that listens on TCP
Remote exploitation of a design error vulnerability in Symantec Corp.'s
Symantec System Center may allow an attacker to execute arbitrary code
with SYSTEM privileges.
The vulnerability exists within the 'Intel File Transfer' service, which
runs the xfr.exe application. When sent a properly formatted request,
this service will extract a string from the request, and use it as the
path of a program to execute as a new Process. The process will be
started with SYSTEM privileges.
Exploitation of this vulnerability allows an attacker to execute
arbitrary code with SYSTEM privileges. In order to exploit this
vulnerability, an attacker must be able to establish a TCP session on
port 12174 with the vulnerable host.
The vulnerable service is actually part of LANDesk Management Suite. It
is not clear whether the behavior described is part of the intended
functionality of the program. However, the manner in which the service
is being used by the Symantec System Center is unsafe.
In a default client type installation, the Symantec System Center is not
installed. The System Center would normally be found on the network
administrator's system. In addition, the Alert Management System
Console is not a default option in the installation of the System

alerts in their environments, and disable or uninstall AMS as a
