Directory traversal vulnerability in SmartSoft Ltd SmartFTP Client 4.0.1124.0, and possibly other versions before 4.0 Build 1133, allows remote FTP servers to overwrite arbitrary files via a "..\" (dot dot backslash) in a filename. NOTE: some of these details are obtained from third party information.
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.
