Hi all,
My point was that Zope is revealing internal information that is believed to
be private and invisible for the Internet users.
It happens in its default (debug) installation and even after -D option is
removed from the startup script.
I try some XML-RPC requests against www.zope.org (2.3.2) and against the
default 2.5.0 installation for Windows (with and without -D option).
In both cases Zope was reviling the physical location of the distribution.
In the case of www.zope.org it was reviling even information about it's
internal network (this may be also possible in 2.5.0 but I do not have the
time to create complicated enough configuration).
In general Zope have not to reveal any physical information neither about
it's installation nor about the internal network behind it.
If you need to print traces - use relative paths to the server root.
If the debug option is omitted - just print the error and do not print any
stack dumps at all!
People have to be aware that the default installation is in debug mode and
the results of that.
I believe many people will be surprised to learn that they are exposing
information about their private networks and server setups.
Finally two clarifications:
1. Zope 2.3.2 do support XML-RPC. Try example one against www.zope.org it
will work just fine!
2. Zope Zope 2.5.0 in it's default installation (debug mode) still is
revealing information about the physical location of the installed server.
See the dump in example two. It is produced as a result of the XML-RPC
example from my first e-mail.
Regards,
Rossen
