Jay,

This is incorrect.  You can traverse directories within your root using "../" with Parent Paths disabled, but if you enable it, you can go outside your root so long as the file permissions allow it.  Here's a quote from the KB article that you linked to:
"The Parent Paths option (the AspEnableParentPaths metabase property) permits you to use ".." in calls to functions such as MapPath by allowing paths that are relative to the current directory using the ..\notation. Setting this property to True may constitute a security risk because an include path can access critical or confidential files outside the root directory of the application."

Enabling parent paths doesn't allow you to actually enter ../../../../../ and transverse directories into your URL string!

It simply allows you to use ../ in your ASP and SSI includes!

Goodness gracious.

I beg to differ.  IMO, Enabling Parent Paths is one of the biggest security risks for a Web server, and IIS disables them by default because of this.  Most exploits require multiple configuration mistakes to exploit, and if you enable Parent Paths, it increases your likelihood of being hacked many times over.  If you look at your logging of websites on your server, you will likely see entries around 200 at a time from script kiddies, most of which are seeking to exploit configurations where parent paths are enabled.

The proper way to approach this would be to create a virtual directory under the website, and configure an exclusive group as having permissions for the Declude directory.

Practically speaking, the security risks related to parent paths are
near zero.  On scale of 0 to 100, having parent paths enabled would be a
.01, assuming your NTFS permissions are tight.

Sorry, no they will not be enabled. That is a security risk I am not
going
to open up on my server.

Aside from the web admin, are there any other fixes or feature
enhancements?  The release notes reference 4.0.9.4 ...

Thanks!
