Descriptions

The default configuration of smbd in Samba before 3.3.11, 3.4.x before 3.4.6, and 3.5.x before 3.5.0rc3, when a writable share exists, allows remote authenticated users to leverage a directory traversal vulnerability, and access arbitrary files, by using the symlink command in smbclient to create a symlink containing .. (dot dot) sequences, related to the combination of the unix extensions and wide links options.

La configuración por defecto de smbd en Samba en versiones anteriores a v3.3.11, v3.4.x anteriores a v3.4.6, y v3.5.x anteriores a v3.5.0rc3, cuando existe una carpeta compartida, permite a usuarios remotos autenticados utilizar una vulnerabilidad de salto de directorio y acceder a ficheros de forma arbitraria, mediante el uso de un comando de enlace simbólico en smbclient para crear un enlace simbólico que contenga secuencias .. (punto punto), relacionado con la combinación de extensiones unix y opciones amplias de enlaces.
