Bug vulnerability classBuffer Overflow
Bug descriptionThe target ftp server seems to be running a Titan FTP Server prior 3.22 which is vulnerable to a buffer overflow in the CWD command. This may be used for a denial of service or to run arbitrary code within the context of the server system. An attacker may gain elevated privileges and completely compromise the target host.
Bug solutionInstall the patches for the affected version or upgrade to the latest software version. An Intrusion Prevention System (IPS) may also be able to prevent buffer overflow vulnerabilities as like this one. The ftp server should be deactivated or de-installed if not necessary. 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.
