Descriptions

The Reviews Plus WordPress plugin before 1.2.14 does not validate the submitted rating, allowing submission of long integer, causing a Denial of Service in the review section when an authenticated user submit such rating and the reviews are set to be displayed on the post/page

El plugin Reviews Plus de WordPress versiones anteriores a 1.2.14, no comprueba la valoración enviada, permitiendo el envío de enteros largos, causando una Denegación de Servicio en la sección de valoraciones cuando un usuario autenticado envía dicha valoración y las valoraciones están configuradas para ser mostradas en el post/página

The Reviews Plus plugin for WordPress is vulnerable to Denial of Service in versions before 1.2.14. This is due to an unknown part of the file post/page of the component Rating Submission Handler. The manipulation with an unknown input leads to a denial of service vulnerability. This makes it possible for authentication attackers, a authentication is necessary for exploitation to cause a Denial of Service in the review section when an authenticated user submit such rating and the reviews are set to be displayed on the post/page.
