Moxieplayer Content Spoofing

`Hello list!  
  
This are Content Spoofing vulnerabilities in TinyMCE and WordPress. Which  
I've disclosed on Wednesday.  
  
In 2011 I already wrote about Content Spoofing in Moxieplayer, when I wrote  
concerning multiple vulnerabilities in TinyMCE  
(http://securityvulns.ru/docs27349.html), which is a component of Media  
plugin for TinyMCE (it's a part of core of TinyMCE). This visual editor is  
bundled with hundreds of web applications, particularly with WordPress. This  
flash file is bundled with WP since version 3.3.  
  
-------------------------  
Affected products:  
-------------------------  
  
Vulnerable are versions TinyMCE 3.4b2 - 4.0b3.  
  
For the first vulnerability versions WordPress 3.3 - 3.4.2 are vulnerable.  
For the second vulnerability versions WordPress 3.3 - 3.5.1 are vulnerable.  
This hole was fixed in WordPress 3.5.2 (note that WP developers incorrectly  
called this CS hole as XSS in announcement at their site, at that in codex  
they wrote correctly).

Details:  
----------  
  
Content Spoofing (WASC-12):  
  
If previous vulnerability, which I found in 2011, looked the next (since  
TinyMCE 3.4b2 and in version 3.4.7 it was fixed):  
  
http://site/moxieplayer.swf?url=http://site2/1.flv  
  
Then recently new vulnerability was found (by Wan Ikram), which allows to  
bypass protection and conduct CS attack:  
  
http://site/moxieplayer.swf#?url=http://site2/1.flv  
  
In June this vulnerability was fixed. Updated version of Moxieplayer is  
present in TinyMCE 4.0.  
  
In WordPress the attack with using of this flash-file looks the next.  
  
The first variant (WP 3.3 - 3.4.2):  
  
http://site/wp-includes/js/tinymce/plugins/media/moxieplayer.swf?url=http://site2/1.flv  
  
The second variant (WP 3.3 - 3.5.1):  
  
http://site/wp-includes/js/tinymce/plugins/media/moxieplayer.swf#?url=http://site2/1.flv

Timeline:  
------------   
  
2013.06.21 - released WP 3.5.2 with updated version of Moxieplayer.
