BACKGROUNDER:
Splatt Forum is a MySQL driven, PHP-based forum system that fully
integrates in
to PHP-Nuke, the popular CMS system by Fransisco Burzi.
INTRODUCTION:
We have discovered two vulnerabilities in the vanilla version of
Splatt Forum 4.0 for PHP-Nuke 6.0; an XSS Vulnerability and an
HTML/Code Injection Flaw.
The vulnerabilities and accompanying exploits were discovered and
executed upon only one web site, and verified by Webmaster
(webmaster@frame4.com).

http://www.frame4.com/content/advisories/FSA-2003-001.txt
VENDOR CONTACT:
None. We didn't contact the vendor as 'Splatt' has a very bad track
record when it comes to replying to security reports and fixing
issues. The web site of the vendor is almost entirely in Italian
which makes vendor contact difficult.
VULNERABILITY DESCRIPTION:
Please refer to the 'Technical Description' section below, for full
description
of the problem(s).
VULNERABLE APPLICATION(S)/PACKAGE(S)/VERSION(S):
"Out-of-the-box" version of Splatt Forum 4.0 for PHP-Nuke 6.0.
Although this is the ONLY version tested for the moment, it is highly
possible
that other versions are open to similar attacks.
SOLUTION/VENDOR INFORMATION/WORKAROUND:
There are various possible solutions going around at the forums at
splatt.it, though the forums are in Italian and the English
translations are often poor.
Recently, Splatt Forum 4.0 Fix 1 has been released; but this is yet
untested.
TECHNICAL DESCRIPTION - EXPLOIT/CONCEPT CODE:
[001] XSS Vulnerability
Post a message (Anonymous is OK) containing the following message
body:
#
Some test text for fun <script>alert(document.cookie);</script> some more
text
goes here...
#
This causes the rendering of the script upon reading (loading) of the
page by the next user. The JS is rendered FIRST, before the user can
perform a cancel action.
[002] HTML/Code Injection Flaw
Perform a search with the keywords:
<iframe src="http://somesite.com">
Upon rendering of the search results the remote site or any local
page will be rendered in the IFRAME. I am sure other JS exploits are
renderable as well, especially the IE 5-6 crash exploits (null
objects) and remote JS cookie snarfing.
CREDITS:
The vulnerabilities outlined in this advisory and accompanying sample
code have been discovered by morning_wood
(morning_wood@thepub.co.za) of Morning Wood,Inc
(http://take.candyfrom.us/).
At the time of discovery this vulnerability was considered 0-day as
the related testing was performed "on the fly" as a curiosity
test. The above exploits have not been circulated through the
underground community and are presented here as a PUBLIC DISCLOSURE.
REFERENCES:
None.
