A path traversal issue exists in file uploading feature of multiple versions of PowerCMS. Arbitrary files may be overwritten by a product 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.
