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.
