Tumulus For Typepad Cross Site Scripting

`-------------------------  
Affected products:  
-------------------------  
  
Vulnerable are all versions of widget Tumulus for Typepad.  
  
----------  
Details:  
----------  
  
This XSS is similar to XSS vulnerability in WP-Cumulus, because it's using  
tagcloud.swf made by author of WP-Cumulus. About such vulnerabilities I  
wrote in 2009-2011, particularly about millions of flash files tagcloud.swf  
which are vulnerable to XSS attacks I mentioned in my article XSS  
vulnerabilities in 34 millions flash files  
(http://lists.webappsec.org/pipermail/websecurity_lists.webappsec.org/2010-January/006033.html).  
  
XSS (WASC-08):  
  
http://site/path/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  
  
At his own site the author keeps file tagcloud-download.swf, which he  
recommends to rename on tagcloud.swf.  
  
Code will execute after click. It's strictly social XSS. Also it's possible  
to conduct (like in WP-Cumulus) HTML Injection attack.
