VHTTPD32 is used as part of the PWS on a 9x or NT client.

Generally it would only be run to serve web pages to a user on the same
machine. We use it for example for FrontPage files stored on the local
PC with search results.

If you had console access PWS is probably the least of the worries!!

That's hardly overflow in FP, VHTTPD32 does not seem to be part of WindowsNT
and more hardly of Frontpage (could be some old version of course), what
operating system are you using?

This seems to be  overflow in HTTP (Web Server, PWS or IIS) and for
WIndowsNT it was handled long time ago in some postfix and service packs.

It would be good idea to include complete information about the system you
are testing, otherwise it is useless.

Hello,

First remote FrontPage exploit?

How about this one:
<A HREF="http://server/AAAAAAAAAAAA<a">http://server/AAAAAAAAAAAA<a</A> lots of A>AAAAAA

FP will overflow and someone will see this message:

VHTTPD32 caused an invalid page fault in
module <unknown> at 0000:41414141.

Tested on FP 3.0.2.926. Maybe others?
