Descriptions

The BackWPup plugin for WordPress is vulnerable to Directory Traversal in versions up to, and including, 4.0.1 via the Log File Folder. This allows authenticated attackers to store backups in arbitrary folders on the server provided they can be written to by the server. Additionally, default settings will place an index.php and a .htaccess file into the chosen directory (unless already present) when the first backup job is run that are intended to prevent directory listing and file access. This means that an attacker could set the backup directory to the root of another site in a shared environment and thus disable that site.

El complemento BackWPup para WordPress es vulnerable a Directory Traversal en versiones hasta la 4.0.1 incluida a través de la carpeta de archivos de registro. Esto permite a los atacantes autenticados almacenar copias de seguridad en carpetas arbitrarias en el servidor, siempre que el servidor pueda escribir en ellas. Además, la configuración predeterminada colocará un archivo index.php y .htaccess en el directorio elegido (a menos que ya esté presente) cuando se ejecute el primer trabajo de copia de seguridad, cuyo objetivo es evitar la lista de directorios y el acceso a archivos. Esto significa que un atacante podría establecer el directorio de respaldo en la raíz de otro sitio en un entorno compartido y así desactivar ese sitio.
