CVE-2019-1967 (CNNVD-201908-2141)
中文标题:
Cisco NX-OS Software 资源管理错误漏洞
英文标题:
Cisco NX-OS Software Network Time Protocol Denial of Service Vulnerability
漏洞描述
中文描述:
Cisco NX-OS Software是美国思科（Cisco）公司的一套交换机使用的数据中心级操作系统软件。 Cisco NX-OS Software中的Network Time Protocol (NTP)功能存在资源管理错误漏洞。远程攻击者可借助Mode 7 NTP数据包洪泛该设备利用该漏洞造成拒绝服务。以下产品及版本受到影响：Cisco MDS 9000 Series Multilayer Switches；Nexus 3000 Series Switches；Nexus 3500 Platform Switches；Nexus 3600 Platform Switches；Nexus 5500 Platform Switches；Nexus 5600 Platform Switches；Nexus 6000 Series Switches；Nexus 7000 Series Switches；Nexus 7700 Series Switches；Nexus 9000 Series Switches（standalone NX-OS mode）；Nexus 9500 R-Series Switching Platform。
英文描述:
A vulnerability in the Network Time Protocol (NTP) feature of Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to excessive use of system resources when the affected device is logging a drop action for received MODE_PRIVATE (Mode 7) NTP packets. An attacker could exploit this vulnerability by flooding the device with a steady stream of Mode 7 NTP packets. A successful exploit could allow the attacker to cause high CPU and memory usage on the affected device, which could cause internal system processes to restart or cause the affected device to unexpectedly reload. Note: The NTP feature is enabled by default.
