-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft FrontPage 98 for Windows 
-------------------------------------------------------------------------------

SYMPTOMS
========

Users running FrontPage Personal Web Server 1.0 (vhttpd32.exe version
3.0.2.xxxx) under the Microsoft Windows 95 or Windows 98 operating systems are
vulnerable to unauthorized users accessing their files using a specific
non-standard URL. The unauthorized users would have to know the exact file name
to access it.

Users running FrontPage Personal Web Server on Microsoft Windows NT are not
affected. Furthermore, most users of Microsoft FrontPage are not affected as the
FrontPage Personal Web Server is available on the FrontPage CD, but was only
installed by default with FrontPage 1.1. Subsequent versions of FrontPage
installed Microsoft Personal Web Server 2.0, which is not affected by this
issue.

CAUSE
=====

This vulnerability involves the ability of a malicious user to bypass the
server's normal file access controls by entering a non-standard URL. The file
must be specifically requested by name, so the malicious user would need to
already know the name of the file or correctly guess it. The vulnerability only
affects users of FrontPage Personal Web Server 1.0 (vhttpd32.exe version
3.0.2.xxxx) to host their own Web site.

RESOLUTION
==========

A fully supported patch is available to fix this vulnerability, and Microsoft
recommends that affected customers download and install it.
