Network Time Protocol NTP Mode 6 Scanner (97861)

Post by paraspiral » 2018/12/12 17:05:34

Issue: Nessus has identified all my CENTOS servers with this vulnerability Network Time Protocol NTP Mode 6 Scanner (97861)
OS: 6.1
Tech Note from Redhat: https://access.redhat.com/solutions/690293
Instructions I followed: I changed the /etc/ntp.conf to
restrict default kod nomodify notrap nopeer noquery
restrict -6 default kod nomodify notrap nopeer noquery

This appears to NOT have solved the issue. Any advice on what would make this NTP mode 6 vulnerability go away?

And restarted ntpd after making that change?
CentOS 6 will die in November 2020 - migrate sooner rather than later!
CentOS 5 has been EOL for nearly 3 years and should no longer be used for anything!
