Nessus Scan Report ------------------ SUMMARY - Number of hosts which were alive during the test : 1 - Number of security holes found : 1 - Number of security warnings found : 4 - Number of security notes found : 2 TESTED HOSTS 192.168.1.2 (Security holes found) DETAILS + 192.168.1.2 : . List of open ports : o sunrpc (111/tcp) (Security warnings found) o sunrpc (111/udp) (Security warnings found) o auth (113/tcp) o unknown (113/udp) o general/tcp (Security hole found) o general/udp (Security notes found) o unknown (2049/udp) (Security warnings found) o general/icmp (Security warnings found) . Warning found on port sunrpc (111/tcp) The RPC service portmapper V2 is running on this port If you do not use it, disable it, as it is a potential security risk . Warning found on port sunrpc (111/udp) The RPC service portmapper V2 is running on this port If you do not use it, disable it, as it is a potential security risk . Vulnerability found on port general/tcp : The TCP sequence numbers of the remote host are always incremented by 64000, so they can be guessed rather easily. A cracker may use this flaw to spoof TCP connections easily. Solution : contact your vendor for a patch Risk factor : High . Information found on port general/tcp Nmap found that this host is running AmigaOS AmiTCP/IP 4.3 . Information found on port general/udp For your information, here is the traceroute to 192.168.1.2 : 192.168.1.2 . Warning found on port unknown (2049/udp) The nfsd RPC service is running. There is a bug in older versions of this service that allow an intruder to execute arbitrary commands on your system. Make sure that you have the latest version of nfsd Risk factor : High CVE : CAN-1999-0832 . Warning found on port general/icmp The remote host answers to an ICMP timestamp request. This allows an attacker to know the date which is set on your machine. This may help him to defeat all your time based authentifications protocols. Solution : filter out the icmp timestamp requests (13), and the outgoing icmp timestamp replies (14). Risk factor : Low CVE : CAN-1999-0524 ------------------------------------------------------ This file was generated by the Nessus Security Scanner
