Joomulus Cross Site Scripting

`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   
(http://websecurity.com.ua/3665/), 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 (http://websecurity.com.ua/3789/).  
  
XSS:  
  
http://site/modules/mod_joomulus/tagcloud.swf?mode=tags&tagcloud=%3Ctags%3E%3Ca+href='javascript:alert(document.cookie)'+style='font-size:+40pt'%3EClick%20me%3C/a%3E%3C/tags%3E  
  
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:  
  
http://site/wp-content/plugins/wp-cumulus/tagcloud.swf?mode=tags&tagcloud=%3Ctags%3E%3Ca+href='http://websecurity.com.ua'+style='font-size:+40pt'%3EClick%20me%3C/a%3E%3C/tags%3E  
  
Vulnerable are Joomulus 2.0 and previous versions.  
  
I mentioned about this vulnerability at my site   
(http://websecurity.com.ua/3801/).
