Title: 多款Cisco产品NX-OS Software SNMP拒绝服务漏洞

Description:

Cisco Nexus 2000 Series Switches等都是美国思科（Cisco）公司的产品。Cisco Nexus 2000 Series Switches等都是交换机设备。Fabric Modules是一款交换机矩阵模块。NX-OS Software是运行在其中的一套交换机使用的数据中心级操作系统软件。Simple Network Management Protocol（SNMP）input packet processor是其中的一个SNMP（简单网络管理协议）输入包管理模块。

多款Cisco产品中的NX-OS Software的SNMPinput packet processor存在安全漏洞，该漏洞源于程序未能正确的验证SNMP数据包中的SNMP协议数据单元（PDUs）。远程攻击者可通过向受影响设备发送特制的SNMP数据包利用该漏洞造成受影响设备上的SNMP应用程序重启。

Severity: 高

CWE

CWE-20

Summary

A vulnerability in the Simple Network Management Protocol (SNMP) input packet processor of Cisco NX-OS Software could allow an authenticated, remote attacker to cause the SNMP application on an affected device to restart unexpectedly. The vulnerability is due to improper validation of SNMP protocol data units (PDUs) in SNMP packets. An attacker could exploit this vulnerability by sending a crafted SNMP packet to an affected device. A successful exploit could allow the attacker to cause the SNMP application to restart multiple times, leading to a system-level restart and a denial of service (DoS) condition. This vulnerability affects Nexus 2000 Series 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 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: CSCuw99630, CSCvg71290, CSCvj67977.
