SYMPTOMS
Microsoft has released a patch that eliminates a security vulnerability in a component that is a part of Windows 2000. The vulnerability could allow a malicious Web site operator to learn the names and properties of files and folders on the computer of a visiting user.

An ActiveX control that is included as part of the Indexing Service is incorrectly marked as &quot;safe for scripting.&quot; Because of this, the ActiveX control may be started by Web site programs. This control could be used to enumerate files and folders, and to view their properties. Note that it would not be necessary for the Indexing service to be running for the vulnerability to be exploited. However, if it were running, the control could also be used to search for files that contain specific words. The vulnerability could not be used to read files, except by using a scenario that is described in the following Microsoft Security Bulletin:

http://www.microsoft.com/technet/treeview/default.asp?url=/technet/security/bulletin/MS00-098.mspx

The vulnerability could not be used to change, add, or delete information on your computer.

NOTE: A patch has been provided for the Indexing service version 3.0, but not for Index Server 2.0. This is primarily due to the different delivery methods that are used for these two products. Indexing service 3.0 is included as a part of all versions of Windows 2000, and because of this, the vulnerability could affect all Windows 2000 users. However, Index Server 2.0 is included as a part of the Windows NT 4.0 Option Pack. Because of this, to be affected by the vulnerability in Index Server 2.0, a Web master would need to browse untrusted Internet sites from his own Web server, and this is contrary to normal recommended practices.

Note that if you applied an earlier version of the fix that is described in this article, you may receive the following error message when you view ASP Web pages that use JavaScript:

16386 No such interface supported

The version of the fix that is described in this article resolves this problem.
