Vulnerability Description
The ftp_PORT function in FTPServer.py in pyftpdlib before 0.2.0 does not prevent TCP connections to privileged ports if the destination IP address matches the source IP address of the connection from the FTP client, which might allow remote authenticated users to conduct FTP bounce attacks via crafted FTP data, as demonstrated by an FTP bounce attack against a NAT server, a related issue to CVE-1999-0017.

G.rodola pyftpdlib FTPServer.py文件权限许可和访问控制漏洞
Vulnerability Description
pyftpdlib(Python FTP server library)提供了高级的可移植的编程接口，用来实现异步的FTP服务器的功能。 pyftpdlib 0.2.0版本中的FTPServer.py文件中的ftp_PORT函数，如果目标IP地址匹配从FTP客户端连接的源IP地址，则不能阻止TCP连接到特权端口。远程认证用户可以借助特制FTP数据进行FTP反弹攻击。该漏洞已通过一对一个NAT服务器的FTP反弹攻击得到证实，与CVE-1999-0017的问题有关。
