New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 5.9
SynopsisAn ONC RPC portmapper is running on the remote host.
DescriptionThe RPC portmapper is running on this port.
The portmapper allows someone to get the port number of each RPC service running on the remote host by sending either multiple lookup requests or a DUMP request.
This service should only run on port 111. However on some operating systems it also listens on different UDP ports. This might allow an attacker to circumvent firewall rules.
SolutionDisable this service if RPC are not used, or update your firewall rules if needed.
