Descriptions

The Insight Core WordPress plugin through 1.0 does not have any authorisation and CSRF checks in the insight_customizer_options_import (available to any authenticated user), does not validate user input before passing it to unserialize(), nor sanitise and escape it before outputting it in the response. As a result, it could allow users with a role as low as Subscriber to perform PHP Object Injection, as well as Stored Cross-Site Scripting attacks

El plugin Insight Core de WordPress versiones hasta 1.0, no presenta ninguna comprobación de autorización y CSRF en el insight_customizer_options_import (disponible para cualquier usuario autenticado), no comprueba la entrada del usuario antes de pasarla a unserialize(), ni la sanea y escapa antes de mostrarla en la respuesta. Como resultado, podría permitir a usuarios con un rol tan bajo como el de suscriptor llevar a cabo una inyección de objetos de PHP, así como ataques de tipo Cross-Site Scripting Almacenado
