`Hello list!  
  
I want to warn you about Cross-Site Scripting, Full path disclosure, Abuse  
of Functionality and Denial of Service vulnerabilities in Live Wire Edition  
theme for WordPress. It's commercial theme for WP by WooThemes.  
  
-------------------------  
Affected products:  
-------------------------  
  
Vulnerable are Live Wire Edition 2.3.1 and previous versions. XSS is  
possible only in old versions of the theme. Recently in version Live Wire  
Edition 2.4 most of these vulnerabilities were fixed (but there were still  
left many not fixed FPD).

About such AoF and DoS vulnerabilities I wrote in article Using of the sites  
for attacks on other sites  
(http://lists.grok.org.uk/pipermail/full-disclosure/2010-June/075384.html).  
  
Beside folder /livewire-edition/, this theme also can be placed in folder  
/livewire-package/ (which includes all three themes of Live Wire series).  
  
------------  
Timeline:  
------------  
  
2011.02.01 - announced at my site.  
2011.02.01 - informed developers.  
2011.02.04-12 - conversation about fixing holes in all their themes for  
WordPress. At first they tried to fix all these holes in themes at their own  
sites.

2011.04.08 - disclosed at my site.
