Subject: Insecure XML-RPC handling in Zope reveals the distribution physic
al location.
Date: Tue, 1 Oct 2002 09:57:27 -0400
Zope versions pre 2.5.1b2 do not handle correct some XML-RPC request.
1. Summary:
Zope (www.zope.org) will reveal the complete physical location where the
server and its components are installed if it receives "incorrect" XML-RPC
requests.
In some cases it will reveal also information about the serves in the
protected LAN (10.x.x.x for example) on which current server is relaying.
2. Details:
A request like the quoted below will cause Zope to produce stack traces in
the response that will reveal the information mentioned above.
See http://collector.zope.org/Zope/359 for more details.
Ironically the quoted request was an example how to use XML-RPC.
Note that starting Zope without -D option won't stop the exposure.
telnet localhost 8080
POST /Documentation/comp_tut HTTP/1.0
Host: localhost
Content-Type: text/xml
Content-length: 93
<?xml version="1.0"?>
