Descriptions

The WordPress File Sharing Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in versions up to, and including, 2.0.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.

El plugin WordPress File Sharing para WordPress es vulnerable a Cross-Site Scripting (XSS) almacenado a través de la configuración de administración en versiones hasta, e incluyendo, la 2.0.3 debido a la insuficiente sanitización de entrada y escape de salida. Esto hace posible que atacantes autenticados, con permisos de nivel de administrador y superiores, inyecten scripts web arbitrarios en páginas que se ejecutarán cada vez que un usuario acceda a una página inyectada. Esto solo afecta a las instalaciones multisitio y las instalaciones en las que se ha deshabilitado "unfiltered_html".
