CVSS 3.1
5.3 mediumCVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:H/A:NCVE-2018-7170
Medium (5.3). EPSS 2.7% chance of exploitation in the next 30 days.
ntpd in ntp 4.2.x before 4.2.8p7 and 4.3.x before 4.3.92 allows authenticated users that know the private symmetric key to create arbitrarily-many ephemeral associations in order to win the clock selection of ntpd and modify a victim's clock via a Sybil attack. This issue exists because of an incomplete fix for CVE-2016-1549.
