Directory traversal vulnerability in JCraft JSch before 0.1.54 on Windows, when the mode is ChannelSftp.OVERWRITE, allows remote SFTP servers to write to arbitrary files via a ..\ (dot dot backslash) in a response to a recursive GET command.
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.
