in an installation routine associated with Microsoft(r) Systems
Management Server (SMS). If particular features have been enabled, the

local machine.

Issue
=====
If the SMS 2.0 Remote Control feature has been installed and enabled on
a machine, the folder in which the remote agent resides has its
permissions set to Everyone Full Control by default. If a malicious
user replaced the client code with code of his or her choosing, it
would run automatically in a system context the next time he or she
rebooted the machine and logged on. The vulnerability exists only if
the Remote Control feature has been enabled - no other SMS features
are affected by it.
