Aside: ability to view ASP/ColdFusion code

Thu Jul 2 17:56:27 UTC 1998

This applies as well to perl and cgi scripts (cgi in iis3.0)

For example:
http://www.activestate.com/lyris/lyris.pl::$DATA

MS hasn't fixed their own site (heh), but they promise a fix today.
http://www.microsoft.com/default.asp::$DATA

In the meantime, Christoph Wille <Christoph.Wille at softwing.com> from Sofwing
has graciously
made available an IIS ISAPI filter that will protect a site from the ::$DATA
vulnerability. You can find it at
http://www.softwing.com/iisdev/ddatafix/
