Patch Available for Taskpads Scripting Vulnerability

Microsoft has released a patch that eliminates a vulnerability in the
Taskpads feature, which is provided as part of the Microsoft(r) Windows=
(r)
98 Resource Kit, Windows 98 Resource Kit Sampler, and BackOffice(r) Res=
ource
Kit, second edition. The vulnerability could allow a malicious web site
operator to run executables on the computer of a visiting user. Only
customers who have installed one of the affected products and who surf =
the
web using the machine on which it is installed are at risk from this
vulnerability.
A fully supported patch is available to remove the Taskpads functionali=

and Microsoft recommends that affected customers download and install i=

Issue
=3D=3D=3D=3D=3D
Taskpads is a feature provided by several Microsoft Windows Resource Ki=
t
products, as detailed below in Affected Software Versions. It is part o=
f the
Resource Kits' Tools Management Console Snap-in, and allows users to vi=
ew
and run Resource Kit Tools via an HTML page rather than through the sta=
ndard
Large Icon, Small, Icon, List, and Detailed Views. A vulnerability exis=
ts
because certain methods provided by Taskpads are incorrectly marked as =
"safe
for scripting" and can be misused by a web site operator to invoke
executables on a visiting user's workstation without their knowledge or
permission.
The affected products are, by default, not installed on Windows 95, Win=
dows
98 or Windows NT=AE. The Windows 98 Resource Kit and Resource Kit Sampl=
er can
only be installed on Windows 98. The BackOffice Resource Kit can be
installed on Windows 95, Windows 98 or Windows NT, but is most commonly
installed on Windows NT servers, which, per recommended security practi=
ces,
usually will not be used for web surfing.
While there have not been any reports of customers being adversely affe=
cted
by these problems, Microsoft is releasing a patch to proactively addres=
s
this issue. The patch for this issue works by removing the Taskpads
functionality, which is rarely used. It does not affect any other featu=
res
of the affected products.
