Descriptions

The Simple Download Monitor WordPress plugin before 3.9.5 does not escape the "File Thumbnail" post meta before outputting it in some pages, which could allow users with a role as low as Contributor to perform Stored Cross-Site Scripting attacks. Given the that XSS is triggered even when the Download is in a review state, contributor could make JavaScript code execute in a context of a reviewer such as admin and make them create a rogue admin account, or install a malicious plugin

El plugin Simple Download Monitor de WordPress versiones anteriores a 3.9.5, no escapa de la meta del post "File Thumbnail" antes de mostrarla en algunas páginas, que podría permitir a usuarios con un rol tan bajo como el de Contribuyente llevar a cabo ataques de tipo Cross-Site Scripting Almacenado. Dado que el ataque de tipo XSS es desencadenado incluso cuando la descarga está en un estado de revisión, el colaborador podría hacer que el código JavaScript se ejecute en un contexto de un revisor como administrador y hacer que creen una cuenta de administrador falsa, o instalar un plugin malicioso
