Vulnerability Assessment Details

bootparamd service

Vulnerability Assessment Summary
Checks the presence of a RPC service

Detailed Explanation for this Vulnerability Assessment

The bootparamd RPC service is running.
It is used by diskless clients to get
the necessary information needed to
boot properly.

If a possible hacker uses the BOOTPARAMPROC_WHOAMI
and provides the correct address of the client,
then he will get its NIS domain back from
the server. Once the attacker discovers the NIS domain
name, it may easily get your NIS password
file.

Solution : filter incoming traffic to prevent connections
to the portmapper and to the bootparam daemon,
or deactivate this service if you do not use it.

Network Security Threat Level: High
