Descriptions

The Formidable Forms – Contact Form, Survey, Quiz, Payment, Calculator Form & Custom Form Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the name field label and description field label parameter in all versions up to 6.7 (inclusive) due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. By default, this only affects multi-site installations and installations where unfiltered_html has been disabled. However, in the formidable settings admins can extend form creation, deletion and other management permissions to other user types, which makes it possible for this vulnerability to be exploited by lower level user types as long as they have been granted the proper permissions.

Esto hace posible que atacantes autenticados, con acceso a nivel de administrador, inyecten scripts web arbitrarios en páginas que se ejecutarán cada vez que un usuario acceda a una página inyectada. De forma predeterminada, esto solo afecta a las instalaciones multisitio y a las instalaciones en las que se ha deshabilitado unfiltered_html. Sin embargo, en la configuración formidable, los administradores pueden extender la creación de formularios, la eliminación y otros permisos de administración a otros tipos de usuarios, lo que hace posible que esta vulnerabilidad sea explotada por tipos de usuarios de nivel inferior siempre que se les hayan otorgado los permisos adecuados.
