Directory traversal vulnerability in Pablo Software Solutions Quick 'n Easy FTP Server 1.77, and possibly earlier versions, allows remote authenticated users to determine the existence of arbitrary files via a .. (dot dot) in the DEL command, which triggers different error messages depending on whether the file exists or not.
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.
