Descriptions

Directus 8 before 8.8.2 allows remote authenticated users to execute arbitrary code because file-upload permissions include the ability to upload a .php file to the main upload directory and/or upload a .php file and a .htaccess file to a subdirectory. Exploitation succeeds only for certain installations with the Apache HTTP Server and the local-storage driver (e.g., when the product was obtained from hub.docker.com).

Directus 8 versiones anteriores a 8.8.2, permite a los usuarios autenticados remotamente ejecutar código arbitrario porque los permisos de carga de archivos incluyen la capacidad de cargar un archivo .php en el directorio de carga principal y/o cargar un archivo .php y un archivo .htaccess en un subdirectorio. La explotación tiene éxito solo para ciertas instalaciones con el servidor HTTP Apache y el controlador de almacenamiento local (por ejemplo, cuando el producto se obtuvo de hub.docker.com)

Monospace Directus Headless CMS versions prior to 8.8.2 suffers from .htaccess rule bypass and arbitrary file upload vulnerabilities.
