New! Plugin Severity Now Using CVSS v3
The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.
Synopsis
An ONC RPC portmapper is running on the remote host.Description
The 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.
Solution
Disable this service if RPC are not used, or update your firewall rules if needed.Plugin Details
