For some Iomega, Lenovo, LenovoEMC NAS devices versions 4.1.402.34662 and earlier, the file upload functionality of the Content Explorer application is vulnerable to path traversal. As a result, users can upload files anywhere on the device's operating system as the root user.
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
