Descriptions

The Calendar Event Multi View WordPress plugin before 1.4.01 does not sanitise or escape the 'start' and 'end' GET parameters before outputting them in the page (via php/edit.php), leading to a reflected Cross-Site Scripting issue.

El plugin de WordPress Calendar Event Multi View versiones anteriores a 1.4.01, no sanea o escapa de los parámetros GET "start" y "end" antes de mostrarlos en la página (por medio de el archivo php/edit.php), conllevando a un problema de tipo Cross-Site Scripting reflejado

The Calendar Event Multi View for WordPress is vulnerable to Reflected Cross-Site Scripting via the ‘'start' and 'end' parameters in versions up to, and including, 1.3.99 due to insufficient input sanitization and output escaping. 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.
