These are Cross-Site Scripting and Full path disclosure vulnerabilities in
multiple themes for WordPress with VideoJS. Earlier I've wrote about
vulnerabilities in VideoJS (http://seclists.org/fulldisclosure/2013/May/21).
This is popular video and audio player, which is used at hundreds thousands
of web sites and in multiple web applications. Google dork for VideoJS shows
446000 results and for WP themes with it shows 171000 (inurl:video-js.swf
Among them are Covert VideoPress, Photolio, Source, Smartstart and Crius.
But there are other vulnerable themes for WP with video-js.swf (these are
free, commercial and custom themes), which can be found with above-mentioned
Google dork. All developers of these plugins, the same as developers of all
other web applications with VideoJS, need to update it in their software.
All versions of Covert VideoPress, Photolio, Source, Smartstart and Crius
Vulnerable are web applications which are using VideoJS Flash Component
3.0.2 and previous versions. Version VideoJS Flash Component 3.0.2 is not
vulnerable to mentioned XSS hole, except XSS via JS callbacks (as it can be
read in repository on github). Also there are bypass methods which work in
the last version, but the developers haven't fixed them due to their low
impact. So update to last version of VideoJS.swf.
Cross-Site Scripting (WASC-08):
There are themes with multiple flash media players: besides VideoJS they
have jPlayer and JW Player. And such themes have all XSS and Content
Spoofing vulnerabilities, which have jPlayer and JW Player (see my
advisories for these flash applications).
Full path disclosure (WASC-13):
All mentioned themes have FPD vulnerabilities in php-files (in index.php and
others), which is typically for WP themes.
2013.02.07 - found XSS vulnerability.
2013.02.08 - informed developers of VideoJS about both vulnerabilities. They
thanked and promised to fix it.
2013.02.23 - reminded VideoJS developers and asked for date of releasing the
2013.03.09 - again reminded developers.
2013.03.26 - again reminded developers.
2013.04.08 - reminded developers on github and resent previous letter to
Zencoder's developers (since Brightcove, which acquired Zencoder, ignored
the hole for two months).
2013.04.08-30 - discussed with developers (on github and by e-mail). And
made my own fix to force developers to fix the hole.
2013.04.30 - developers fixed XSS hole in VideoJS Flash Component 3.0.2 in
source code on github.
2013.05.02 - developers compiled fixed version of swf (after my reminding)
and uploaded to both repositories.
2013.05.02 - tested version 3.0.2 and found that developers haven't fixed
the hole completely and informed them.
