Descriptions

The WordPress File Upload Free and Pro WordPress plugins before 4.16.3 allow users with a role as low as Contributor to perform path traversal via a shortcode argument, which can then be used to upload a PHP code disguised as an image inside the auto-loaded directory of the plugin, resulting in arbitrary code execution.

Los plugins File Upload Free y Pro de WordPress versiones anteriores a 4.16.3, permiten a usuarios con un rol tan bajo como el de Contribuyente llevar a cabo un salto de ruta por medio de un argumento shortcode, que puede ser usado para subir un código PHP disfrazado de imagen dentro del directorio autocargado del plugin, resultando en una ejecución de código arbitrario
