walld service

Vulnerability Assessment Summary
Checks the presence of a RPC service

Detailed Explanation for this Vulnerability Assessment

The walld RPC service is running. It is usually used by the administrator
to tell something to the users of a network by making a message appear
on their screen.

Since this service lacks any kind of authentication, a possible hacker
may use it to trick users into doing something (change their password,
leave the console, or worse), by sending a message which would appear to be
written by the administrator.

It can also be used as a denial of service attack, by continually sending
garbage to the users screens, preventing them from working properly.

Solution : Disable this service.
Network Security Threat Level: Medium
