CVE-2018-7170 is a medium-severity vulnerability affecting NTP versions 4.2.x before 4.2.8p7 and 4.3.x before 4.3.92, impacting products from vendors like HPE, NetApp, and Synology. An authenticated attacker with knowledge of the private symmetric key can exploit this flaw to manipulate a victim's clock through a Sybil attack by creating numerous ephemeral associations, stemming from an incomplete fix for CVE-2016-1549. The attack requires high attack complexity and low privileges, but can lead to high integrity impact. There is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this CVE.
