Vulnerability Details
Summary
The switch firmware deliverables listed below have addressed the applicable NTP CVEs.
Vulnerability Details:
CVE-ID: CVE-2014-9750
Description: NTP NTPd could allow a remote attacker to obtain sensitive information, caused by an error in ntp_crypto.c when Autokey Authentication is enabled. By sending a malformed packet, a remote attacker could exploit this vulnerability to obtain sensitive information or cause a denial of service.
CVSS Base Score: 4.8
CVSS Temporal Score: See http://exchange.xforce.ibmcloud.com/vulnerabilities/109527
for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:L)
CVE-ID: CVE-2014-9751
Description: Network Time Protocol (NTP) could allow a remote attacker to conduct spoofing attacks, caused by the failure to properly determine whether a source IP address is an IPv6 loopback address by the read_network_packet function. By sending a specially crafted packet, an attacker could exploit this vulnerability to spoof restricted packets.
CVSS Base Score: 5.3
CVSS Temporal Score: See http://exchange.xforce.ibmcloud.com/vulnerabilities/109548
for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N)
CVE-ID: CVE-2015-7974
Description: NTP could allow a remote authenticated attacker to conduct spoofing attacks, caused by a missing key check. An attacker could exploit this vulnerability to impersonate a peer.
CVSS Base Score: 5.3
CVSS Temporal Score: See http://exchange.xforce.ibmcloud.com/vulnerabilities/110019
for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:H/A:N)
CVE-ID: CVE-2015-7973
Description: NTP could allow a remote attacker to launch a replay attack. An attacker could exploit this vulnerability using authenticated broadcast mode packets to conduct a replay attack and gain unauthorized access to the system.
CVSS Base Score: 5.4
CVSS Temporal Score: See
http://exchange.xforce.ibmcloud.com/vulnerabilities/110018 for the
current score for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L)
CVE-ID: CVE-2015-7979
Description: NTP could allow a remote attacker to bypass security restrictions. By sending specially crafted broadcast packets with bad authentication, an attacker could exploit this vulnerability to cause the target broadcast client to tear down the association with the broadcast server.
CVSS Base Score: 6.5
CVSS Temporal Score: See http://exchange.xforce.ibmcloud.com/vulnerabilities/110024
for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L)
CVE-ID: CVE-2015-8138
Description: NTP could allow a remote attacker to bypass security restrictions. By sending a specially crafted packet with an origin timestamp of zero, an attacker could exploit this vulnerability to bypass the timestamp validation check.
CVSS Base Score: 5.3
CVSS Temporal Score: See http://exchange.xforce.ibmcloud.com/vulnerabilities/110025
