If particular features have been enabled, the vulnerability could allow a user to gain elevated privileges on the local machine. Frequently asked questions regarding this vulnerability and the patch can be found at http://www.microsoft.com/technet/security/bulletin/fq00-012.asp 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.
