Hello list! Earlier I've wrote about Content Spoofing and Cross-Site Scripting vulnerabilities in JW Player (http://securityvulns.com/docs28176.html). And I've mentioned that there are near million of web sites with vulnerable flash-file - it's only indexed by Google, and in reality there are much more of them (JW Player is very popular flash video player). Similar vulnerabilities exist in hundreds of web applications. Particularly in the next five plugins for engines MODx CMS, Joomla, Moodle and WordPress, which are using swf-file of JW Player. ------------------------- Affected products: ------------------------- Vulnerable are all versions of JWPlayer for MODx. Vulnerable are all versions of Simple video flash player for Joomla. Vulnerable are all versions of Poodll for Moodle. Vulnerable are all versions of RokBox for Joomla. Vulnerable are all versions of RokBox for WordPress. ---------- Details: ---------- Content Spoofing and XSS are similar to described earlier (http://securityvulns.com/docs28176.html). Only in the plugins (old versions, which I saw) Simple video flash player for Joomla and RokBox for Joomla and WP, in which JWPlayer 4.x is used, there are no CS via playlist and logotype and XSS via parameter playerready and via logotype. The paths to swf-file are the next: JWPlayer for MODx plugin (extra): http://site/embed/player.swf Example of XSS vulnerability. XSS (WASC-08): http://site/embed/player.swf?playerready=alert(document.cookie) Simple video flash player for Joomla: http://site/modules/mod_simple_video_flash_player/jwplayer.swf Poodll for Moodle: http://site/poodll/jwplayer59/jwplayer.swf Example of XSS vulnerability. XSS (WASC-08): http://site/poodll/jwplayer59/jwplayer.swf?playerready=alert(document.cookie) RokBox for Joomla: http://site/plugins/system/rokbox/jwplayer/jwplayer.swf RokBox for WordPress: http://site/wp-content/plugins/wp_rokbox/jwplayer/jwplayer.swf -------------- Mitigation: -------------- At 3rd of June, after my informing, developers of MODx CMS have removed JWPlayer plugin from their official web site. But the file is still online, because it was hosted at another site and it was just a redirect from modx.com to the plugin. Upgrading to the new version of swf-file of JW Player can help mitigate some XSS holes (and the developers are planning to fix other holes later). I mentioned about these vulnerabilities at my site: http://websecurity.com.ua/5988/ Best wishes & regards, MustLive Administrator of Websecurity web site http://websecurity.com.ua
