Bug vulnerability class | Configuration |
Bug description | An attacker can determine the Macintosh FTP server and operating system by grabbing the banner of the FTP server. This information can be used for further enumeration or generic attacks. |
Bug solution | The server should be deactivated or de-installed if not necessary. To make it harder to find the FTP server the daemon could be configured to listen at another port (e.g. 2221). Try to prevent unwanted connection attempts by filtering traffic with firewalling. Alternation of the application banner can confuse an attacker and let him determine the wrong software. |
