Directory traversal vulnerability in Core FTP client 2.1 Build 1565 allows remote FTP servers to create or overwrite arbitrary files via .. (dot dot) sequences in responses to LIST commands, a related issue to CVE-2002-1345. NOTE: this can be leveraged for code execution by writing to a Startup folder.
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.
