depending on the resources you have available there
are two options that works fine...the first one is to
put a hogwash machine (http://hogwash.sourceforge.net)
in front of your web server and to configure it to
drop all the packets that come with a cmd.exe or
whatever other attributes you may be interested
in(cons: if your hogwash device goes down, your web
server becomes unavailable) and a second option that
have worked for me is to use snort compiled with the
flexresp option and to rst_all/rst_snd/rst_rcv the
packets containing in the url "cmd.exe" (or for that
matter, any other attribute)...
