CVE-2018-0395 (CNNVD-201810-999)
中文标题:
Cisco FXOS Software和NX-OS Software 输入验证漏洞
英文标题:
Cisco FXOS and NX-OS Software Link Layer Discovery Protocol Denial of Service Vulnerability
漏洞描述
中文描述:
Cisco Firepower 4100 Series Next-Generation Firewalls等都是美国思科(Cisco)公司的产品。Cisco Firepower 4100 Series Next-Generation Firewalls是一款4100系列的防火墙设备。Nexus 1000V Series Switches是一款1000V系列的交换机设备。FXOS Software是一套运行在思科安全设备中的防火墙软件。NX-OS Software是运行在思科交换机设备中的一套数据中心级操作系统软件。 Cisco FXOS Software和NX-OS Software中的Link Layer Discovery Protocol (LLDP)实现存在输入验证漏洞,该漏洞源于程序没有对LLDP frame包头的type、length、value(TLV)字段执行正确的输入验证。攻击者可通过向界面发送特制的LLDP数据包利用该漏洞造成设备重新加载,导致拒绝服务。以下产品受到影响:Cisco Firepower 4100 Series Next-Generation Firewall;Firepower 9300 Security Appliance;MDS 9000 Series Multilayer Switches;Nexus 2000 Series Switches;Nexus 3000 Series Switches;Nexus 3500 Platform Switches;Nexus 5500 Platform Switches;Nexus 5600 Platform Switches;Nexus 6000 Platform Switches;Nexus 7000 Series Switches;Nexus 7700 Series Switches;Nexus 9000 Series Fabric Switches(处于Application Centric Infrastructure (ACI)模式);Unified Computing System (UCS) 6100 Series Fabric Interconnects;UCS 6200 Series Fabric Interconnects;UCS 6300 Series Fabric Interconnects。
英文描述:
A vulnerability in the Link Layer Discovery Protocol (LLDP) implementation for Cisco FXOS Software and Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition when the device unexpectedly reloads. The vulnerability is due to improper input validation of certain type, length, value (TLV) fields of the LLDP frame header. An attacker could exploit this vulnerability by sending a crafted LLDP packet to an interface on the targeted device. A successful exploit could allow the attacker to cause the switch to reload unexpectedly.
