RE:[Full-Disclosure] XP Remote Desktop Remote Activation

["RandallM" <randallm@xxxxxxxxxxx>]

Would access to command shell be accomplished via the recent ZoneID hole if
such Administration password access is not available? Or perhaps even with
the launching
Of the MS04-028 exploit? Of course any Terminal usage on home pc's are
noticed because users
are locked out. Now terminal servers are a differnet story but user
intervention is still needed.

thank you

<|>XP Remote Desktop Remote Activation

<|>
<|>Information
<|>____________________________________________________________________
<|>Windows XP Professional provides a service called Remote Desktop,
<|>which allows a user to remotely control the desktop as if he or she
<|>were in front of the system locally (ala VNC, pcAnywhere, etc.).
<|>
<|>By default, Remote Desktop is shipped with this service 
<|>turned off and
<|>only the Administrator is allowed access to this service.  It is
<|>possible, however, to modify a series of registry keys that may allow
<|>a malicious user who has already gained a command shell to activate
<|>Remote Desktop and add a user they have created for 
<|>themselves as well
<|>as to hide that user so that it will not show up as a user in the
<|>Remote Desktop user list.  The instructions for this are attached. 
<|>Additionally, I have listed a sample .reg file of the type that is
<|>discussed in the instructions below.
