Descriptions

The CLUEVO LMS, E-Learning Platform WordPress plugin before 1.8.1 does not sanitise and escape Course's module, which could allow high privilege users to perform Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed

El plugin CLUEVO LMS, E-Learning Platform de WordPress versiones anteriores a 1.8.1, no sanea y escapa del módulo Course's, lo que podría permitir a usuarios con altos privilegios llevar a cabo ataques de tipo Cross-Site Scripting incluso cuando la capacidad unfiltered_html está deshabilitada

The CLUEVO LMS, E-Learning Platform WordPress plugin before 1.8.1 does not sanitise and escape Course's module, which could allow high privilege users to perform Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed
The CLUEVO E-Learning Platform plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 1.8.0 due to insufficient input sanitization and output escaping in the Course's module. This makes it possible for high privilege attackers, even when the unfiltered_html capability is disallowed, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
