Bug affectedTYPSoft FTP up to 1.11
Bug not affectedTYPSoft FTP newer than 1.11
Bug vulnerability classBuffer Overflow
Bug descriptionThe remote host seems to be running TYPSoft FTP, a small FTP server. The software version up to 1.11 has a denial of service vulnerability in the RETR command. An attacker may crash the remote server by sending a malformed FTP request.
Bug solutionThe server should be deactivated or de-installed if not necessary. If this is not possible, you should upgrade the software to the latest version. To make it harder to find the server the daemon could be configured to listen at another port (e.g. 8021). 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.
