It's not secret, you can still use /objectIds and /objectValues to find out about things... Secure, yes it is that. But, it's a lot more than a little work. What I was suggesting was something to do the grunt work of all this with the same outcome. oh well...

The MS bug "allows access to any file on the webserver". Whilst in ZOPE you may be able to enter the URL and invoke the object to some degree, unless you have the permissions to do whatever it does, what harm can you do? To me, this seems like more of a "patch by sensible admin" problem than a security hole. > cheers, > > Chris > Have a better one, Curtis Maloney. ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

Re: [Zope] IIS and Zope share same problem :-S
As I already suggested ages ;) ago (and still didn't put into practice) it would here again be best to deny everything that isn't explicitly allowed (e.g. allow whatever ends with _html or .html and deny everything else) but then I would have to go over the whole website and make bazillions of changes ... I fixed the problem temporarily by adding some "FilesMatch/LocationMatch + deny from all" in my httpd.conf. But what else do I have to deny apart from objectIds?

Re: [Zope] IIS and Zope share same problem :-S
Hum... A possible way to solve this problem is to practice the "you can't do ANYTHING but..." policy... And, thus, according proxy roles to the methods that must access it, such as index_html. I know it's constraining but with a little work we can end up with something quite secure & secret. P.-J.
