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中的简单网络管理协议访问控制列功能存在权限许可和访问控制问题漏洞,该漏洞源于当所配置的ACL名称达到最大的32 ASCII字符长度时,程序进行了错误地检查。远程攻击者可利用该漏洞进行SNMP轮询。以下产品及版本受到影响:Cisco Nexus 3000 Series Switches;Nexus 3500 Platform Switches;Nexus 3600 Platform Switches;Nexus 9000 Series Switches(standalone NX-OS mode);Nexus 9500 R-Series Switching Platform。
英文描述:
A vulnerability in the implementation of the Simple Network Management Protocol (SNMP) Access Control List (ACL) feature of Cisco NX-OS Software could allow an unauthenticated, remote attacker to perform SNMP polling of an affected device, even if it is configured to deny SNMP traffic. The vulnerability is due to an incorrect length check when the configured ACL name is the maximum length, which is 32 ASCII characters. An attacker could exploit this vulnerability by performing SNMP polling of an affected device. A successful exploit could allow the attacker to perform SNMP polling that should have been denied. The attacker has no control of the configuration of the SNMP ACL name.
