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. 

First, we need a directory where we have access to on
the victim host...
(Or we can create one if we have enough rights)

ftp://127.0.0.1/

might give us a directory RESTRICTED/ for example
now we do :

ftp://127.0.0.1/RESTRICTED/...%5c/

and we're out of the restricted subdirectory, we have
read access to the whole harddrive

- 漏洞描述

CesarFTP contains a flaw that allows a remote attacker to access arbitrary files outside of the web path. The issue is due to the program not properly sanitizing user input, specifically traversal style attacks (../../) supplied via the GET command.
