Descriptions

Samba 4.x before 4.0.4, when configured as an Active Directory domain controller, uses world-writable permissions on non-default CIFS shares, which allows remote authenticated users to read, modify, create, or delete arbitrary files via standard filesystem operations.

Samba v4.x anterior a v4.0.4, cuando se configura como un controlador de dominio del Directorio ACtivo, utiliza permisos de escritura globales sobre CIFS shares que no están por defecto, lo que permite a usuarios autenticados remotamente leer, modificar, crear o eliminar archivos arbitrariamente a través de operaciones convencionales en el sistema de archivos.
