Descriptions

The EventON plugin through 3.0.5 for WordPress allows addons/?q= XSS via the search field.

El plugin EventON versiones hasta 3.0.5 para WordPress, permite un XSS de addons/?q= por medio del campo de búsqueda

The EventON plugin for WordPress is vulnerable to Reflected Cross-Site Scripting in versions up to, and including 3.0.5. This is due to insufficient escaping and sanitization on the q= parameter. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. Please note this only affects the premium version of this plugin.

WordPress EventON Calendar plugin version 3.0.5 suffers from a cross site scripting vulnerability.
