CVE-2014-9751
6.8 · MEDIUMOverview
CVE-2014-9751 is a medium-severity vulnerability affecting ntp ntp. It was published on October 6, 2015 and has a CVSS 2.0 base score of 6.8 (MEDIUM).
This vulnerability has a CVSS 2.0 base score of 6.8, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
The read_network_packet function in ntp_io.c in ntpd in NTP 4.x before 4.2.8p1 on Linux and OS X does not properly determine whether a source IP address is an IPv6 loopback address, which makes it easier for remote attackers to spoof restricted packets, and read or write to the runtime state, by leveraging the ability to reach the ntpd machine's network interface with a packet from the ::1 address.
Remediation
Check the references section for vendor advisories and patches from ntp. Update ntp to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
