DHCP Server Detection

low Nessus Plugin ID 10663
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

The remote DHCP server may expose information about the associated network.

Description

This script contacts the remote DHCP server (if any) and attempts to retrieve information about the network layout.

Some DHCP servers provide sensitive information such as the NIS domain name, or network layout information such as the list of the network web servers, and so on.

It does not demonstrate any vulnerability, but a local attacker may use DHCP to become intimately familiar with the associated network.

Solution

Apply filtering to keep this information off the network and remove any options that are not in use.
