It is perhaps easier to think of active FTP sessions as Client-Driven and PASV-FTP sessions as Server-Driven. In the past, it was difficult to allow this inbound connection through the firewall to the requested port on the client without permanently opening port 20 connections from outside servers to inside clients for outbound FTP connections. This creates a huge potential vulnerability by allowing any inbound traffic The control connection should be open when transferring data."Patch available for IIS Malformed FTP list Request vulnerability", Microsoft Security Bulletin (MS99-003).

FTP stand for File Transfer Protocol used for the transfer of computer files such as docs, pdf, multimedia and etc between a client and server on a computer network via port 21. Port 21 is default port which gets open when FTP is activated for sharing data. In Standard (PORT) mode, the FTP server always sends data from TCP port 20. The FTP server must open a new connection to the client when it sends data.The process used in this method seeks to limit potential file vulnerability during encryption. FTP is a service that is commonly used in Web Servers from Webmasters for accessing the files remotely.So it is almost impossible not to find this service in one of our clients systems during an engagement.FTP Service Discovery. We can see that the FTP port is open. FireWall-1 FTP Server Vulnerability Background Paper 1, data protect AG.If you have a FTP server behind a FireWall-1, it is possible for an attacker to open TCP connections to certain ports on the machine, and perform limited communication with those services. My understanding of FTP over SSL (ftps) is that it doesnt work well with firewalls and NAT. In an ordinary FTP session, the information about data connections is read, and for NAT modified, by the firewall in order for the firewall to dynamically open the needed ports. If that information is secured by Because the server opens a port and then waits for the client to connect, there is a window ofH D Moore: At the time I was doing a comparison of different vulnerability scanners. I was going over the CyberCop report and one of the vulnerabilities it reported was the "Sequential FTP Passive Port". FTP is the acronym for File Transfer Protocol. It is the Internet standard for transferring files between computers.In addition to vulnerabilities that were discussed earlier in this paper, he notices how the FTP server is sequentially opening ports. 3) The FTP client should be allowed to make TCP connections to port 21, and to accept TCP connections from port 20 to any ephemeral port.Again, the chance of someone finding an open port waiting for connections from port 20 is remote (case 3), but do you trust the Internet Explorer or 230 End ftp> bin 200 Type set to I. ftp> hash Hash mark printing On ftp: (2048 bytes/hash mark) . ftp> put c:write-log.ps1 200 PORT command successful. 125 Data connection already open Transfer starting.
