Descriptions

The WP Ultimate CSV Importer plugin for WordPress is vulnerable to Remote Code Execution in versions up to, and including, 7.9.8 via the '->cus2' parameter. This allows authenticated attackers with author-level permissions or above, if the administrator previously grants access in the plugin settings, to create a PHP file and execute code on the server. The author resolved this vulnerability by removing the ability for authors and editors to import files, please note that this means php file creation is still allowed for site administrators, use the plugin with caution.

El plugin WP Ultimate CSV Importer para WordPress es vulnerable a la ejecución remota de código en versiones hasta, e incluyendo, la v7.9.8 a través del parámetro "->cus2". Esto permite a atacantes autenticados con permisos de nivel autor o superior, si el administrador concede previamente el acceso en la configuración del plugin, crear un archivo PHP y ejecutar código en el servidor. El autor resolvió esta vulnerabilidad eliminando la capacidad de los autores y editores para importar archivos, por favor tenga en cuenta que esto significa que la creación de archivos PHP todavía está permitida para los administrador del sitio. Utilice el plugin con precaución.
