Bug vulnerability classConfiguration
Bug descriptionThe target is running a ftp service. FTP (file transfer protocol) is a protocol for transferring files between systems. The ftp service is used by many applications for data communications. Some systems also allow users to connect to an ftp server to upload and download files. ftp servers are vulnerable to a wide range of attacks designed to retrieve files without authorization (including password files) and execute commands on other parts of the server.
Bug solutionA service if not needed should be de-installed or disabled. If this is not possible, an access control list (ACL) with firewalling should be applied to this port. And if possible change the welcome banner to confuse an attacker and give him false information. Don't allow anonymous ftp access unless it is absolutely necessary. Configure your system to log all ftp accesses and transfers and periodically check these logs for patterns of misuse. Make sure the home directory of your ftp server is not writable and disallow connections from system IDs (including root, uucp, nobody, and bin).
