漏洞描述
中文描述:
Cisco Nexus 3000 Series Switches等都是美国思科（Cisco）公司的产品。Cisco Nexus 3000 Series Switches是一款3000系列交换机。Cisco Nexus 3500 Platform Switches是一款3500系列平台交换机。Cisco Nexus 3600 Platform Switches是一款3600系列平台交换机。Cisco NX-OS Software是一套交换机使用的数据中心级操作系统软件。 Cisco NX-OS Software中存在数据伪造问题漏洞。该漏洞源于网络系统或产品未充分验证数据的来源或真实性。攻击者可利用伪造的数据进行攻击。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 in standalone NX-OS mode；Nexus 9500 R-Series Switching Platform。
英文描述:
A vulnerability in the CLI implementation of a specific command used for image maintenance for Cisco NX-OS Software could allow an authenticated, local attacker to overwrite any file on the file system including system files. These file overwrites by the attacker are accomplished at the root privilege level. The vulnerability occurs because there is no verification of user-input parameters and or digital-signature verification for image files when using a specific CLI command. An attacker could exploit this vulnerability by authenticating to the device and issuing a command at the CLI. Because an exploit could allow the attacker to overwrite any file on the disk, including system files, a denial of service (DoS) condition could occur. The attacker must have valid administrator credentials for the affected device to exploit this vulnerability.
