Joomulus for Joomla vulnerability

Vulnerability in Joomulus for Joomla

Hello Bugtraq!

I want to warn you about Cross-Site Scripting vulnerability in Joomulus 
(mod_joomulus) plugin for Joomla. Which I found at 23.12.2009.

It is similar to XSS vulnerability in WP-Cumulus 
(, because it's using tagcloud.swf made by 
author of WP-Cumulus. About millions of flash files tagcloud.swf which are 
vulnerable to XSS attacks I mentioned in my article XSS vulnerabilities in 8 
millions flash files ( 



Code will execute after click. It's strictly social XSS.

Also it's possible to conduct (like in WP-Cumulus) HTML Injection attack, 
including in those flash files which have protection (in flash files or via 
WAF) against javascript and vbscript URI in parameter tagcloud.

HTML Injection:


Vulnerable are Joomulus 2.0 and previous versions.

I mentioned about this vulnerability at my site
