Vulnerability Discussion

The FTP service provides an unencrypted remote access that does not provide for the confidentiality and integrity of user passwords or the remote session. If a privileged user were to log in using this service, the privileged user password could be compromised. Secure Shell (SSH) or other encrypted file transfer methods must be used in place of this service.

Removing the "vsftpd" package decreases the risk of accidental activation.
