Title: 多款Cisco产品NX-OS Software role-based access control权限提升漏洞

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。role-based access control（RBAC）是其中的一个基于角色的访问控制组件。

多款Cisco产品中的NX-OS Software的RBAC存在权限提升漏洞，该漏洞源于程序为CLI命令分配了未能正确的RBAC权限。远程攻击者可通过对设备进行身份验证利用该漏洞执行被限制的CLI命令。

Severity: 中

CWE

CWE-264

Summary

A vulnerability in role-based access control (RBAC) for Cisco NX-OS Software could allow an authenticated, remote attacker to execute CLI commands that should be restricted for a nonadministrative user. The attacker would have to possess valid user credentials for the device. The vulnerability is due to incorrect RBAC privilege assignment for certain CLI commands. An attacker could exploit this vulnerability by authenticating to a device as a nonadministrative user and executing specific commands from the CLI. An exploit could allow the attacker to run commands that should be restricted to administrative users. These commands could modify the configuration or boot image on the device. This vulnerability affects MDS 9000 Series Multilayer Switches, 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. Cisco Bug IDs: CSCvd77904.
