Microsoft Zero Administration Kit (ZAK) 1.0 and Office97 Backdoor Vulnerability (EDBID:19144)

Zero Administration Kit (ZAK) was designed to allow administrators to (among other things) lock down the NT environment and restrict the user's access to certain applications and system functions.

In an instance where the end-user is not allowed to execute Windows Explorer and other "forbidden applications" (ie Quake), the following workaround was noted:

Open Word or Excel.

Select File:Open. Right click on the background of the File:Open window. A prompt will appear that will allow the user to select "Browse". Browse will open Windows Explorer.

Assuming the user has write access to the temp directory, create a special directory in temp and copy in the executables of the forbidden applications to this directory. These applications can now be executed and will circumvent the policies established by ZAK.

The way to stop the explorer from being an option is to remove it from
under the file association for folders. To do this follow these
directions.

Go to My Computer
Select View and Options
Click on the File Types tab
Find the Folder association and double click to open it
Highlight explore and click Remove

This will remove the explorer option from all right mouse button
calls.

The next area to look at is to give the everyone group Execute rights
only to explorer.exe command. This will allow explorer to run for the
desktop but it will not be available to be added by embedding it into
a Word or Excel document.
