CVE-2018-7170

Disclosure Date: March 06, 2018
Add MITRE ATT&CK tactics and techniques that apply to this CVE.

Description

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.
