Title: NT ZAK and Office97 Backdoor Vulnerability
Severity: INFO
Description:
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.
Affected Products:
- Microsoft Windows NT 4.0
- Microsoft Windows NT 4.0 SP3
- Microsoft Windows NT Enterprise Server 4.0 SP3
- Microsoft Windows NT Server 4.0 SP3
- Microsoft Windows NT Terminal Server 4.0 SP3
- Microsoft Windows NT Workstation 4.0 SP3
- Microsoft Zero Administration Kit (ZAK) 1.0
