CesarFTP Directory Traversal Vulnerability

CesarFTP is a freely available FTP Server for Microsoft Windows 9x/ME systems.

CesarFTP on Windows 98/Me platforms contains a 'directory traversal' vulnerability.

If a user requests to change directories to "..." from within a mapped directory, they will change into the directory above the 'real' directory on the filesystem. At this point they can traverse the filesystem and will have read access to almost every file.

A user must already have an account on the server to take advantage of this vulnerability.

Note: This vulnerability only affects Windows 98/Me systems running CesarFTP.
