Synology DiskStation Manager NTPD Denial of Service (CVE-2018-7184)

high Tenable OT Security Plugin ID 502449

Synopsis

The remote OT asset is affected by a vulnerability.

Description

ntpd in ntp 4.2.8p4 before 4.2.8p11 drops bad packets before updating the received timestamp, which allows remote attackers to cause a denial of service (disruption) by sending a packet with a zero-origin timestamp causing the association to reset and setting the contents of the packet as the most recent timestamp. This issue is a result of an incomplete fix for CVE-2015-7704.
