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。Discovery Protocol是其中的一个Cisco设备发现协议组件。 多款Cisco产品中的FXOS Software和NX-OS Software的Discovery Protocol组件存在输入验证漏洞，该漏洞源于程序没有充分的验证Cisco Discovery Protocol数据包包头。攻击者可通过发送特制的Cisco Discovery Protocol数据包利用该漏洞造成缓冲区溢出，以root用户身份执行任意代码或造成拒绝服务。以下产品受到影响：Cisco Firepower 4100 Series Next-Generation Firewalls；Firepower 9300 Security Appliance；MDS 9000 Series Multilayer Switches；Nexus 1000V Series Switches；Nexus 1100 Series Cloud Services Platforms；Nexus 2000 Series Fabric Extenders；Nexus 3000 Series Switches；Nexus 3500 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 Fabric Switches（在Application Centric Infrastructure (ACI)模式下）；Nexus 9000 Series Switches（在standalone NX-OS模式下）；Nexus 9500 R-Series Line Cards and Fabric Modules；UCS 6100 Series Fabric Interconnects；UCS 6200 Series Fabric Interconnects；UCS 6300 Series Fabric Interconnects。

英文描述:

A vulnerability in the Cisco Discovery Protocol component of Cisco FXOS Software and Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to execute arbitrary code as root or cause a denial of service (DoS) condition on the affected device. The vulnerability exists because of insufficiently validated Cisco Discovery Protocol packet headers. An attacker could exploit this vulnerability by sending a crafted Cisco Discovery Protocol packet to a Layer 2 adjacent affected device. A successful exploit could allow the attacker to cause a buffer overflow that could allow the attacker to execute arbitrary code as root or cause a DoS condition on the affected device. This vulnerability affects the following if configured to use Cisco Discovery Protocol: Firepower 4100 Series Next-Generation Firewalls, Firepower 9300 Security Appliance, MDS 9000 Series Multilayer Switches, Nexus 1000V Series Switches, Nexus 1100 Series Cloud Services Platforms, Nexus 2000 Series Fabric Extenders, Nexus 3000 Series Switches, Nexus 3500 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 Fabric Switches in Application Centric Infrastructure (ACI) mode, Nexus 9000 Series Switches in standalone NX-OS mode, Nexus 9500 R-Series Line Cards and Fabric Modules, UCS 6100 Series Fabric Interconnects, UCS 6200 Series Fabric Interconnects, UCS 6300 Series Fabric Interconnects. Cisco Bug IDs: CSCvc22202, CSCvc22205, CSCvc22208, CSCvc88078, CSCvc88150, CSCvc88159, CSCvc88162, CSCvc88167.
