FTP Supports Cleartext Authentication
Low Nessus Plugin ID 34324
SynopsisAuthentication credentials might be intercepted.
DescriptionThe remote FTP server allows the user's name and password to be transmitted in cleartext, which could be intercepted by a network sniffer or a man-in-the-middle attack.
SolutionSwitch to SFTP (part of the SSH suite) or FTPS (FTP over SSL/TLS). In the latter case, configure the server so that control connections are encrypted.
