New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 4.4
SynopsisThe remote device is missing a vendor-supplied security patch.
DescriptionThe ntpd client in NTP 4.x before 4.2.8p4 and 4.3.x before 4.3.77 allows remote attackers to cause a denial of service via a number of crafted 'KOD' messages. (CVE-2015-7704)
An off-path attacker can send a crafted Kiss of Death (KoD) packet to the client, which will increase the client's polling interval to a large value and effectively disable synchronization with the server.
