中文描述:

Cisco Catalyst 9000是美国思科（Cisco）公司的一个交换机。 Cisco Catalyst 9000 Family 存在安全漏洞，该漏洞源于在初始引导过程中管理系统映像文件数字签名验证的代码功能中检查不当。攻击者可利用该漏洞在系统启动时执行无签名代码。

英文描述:

A vulnerability in the software image verification functionality of Cisco IOS XE Software for the Cisco Catalyst 9000 Family of switches could allow an unauthenticated, physical attacker to execute unsigned code at system boot time. The vulnerability is due to an improper check in the code function that manages the verification of the digital signatures of system image files during the initial boot process. An attacker could exploit this vulnerability by loading unsigned software on an affected device. A successful exploit could allow the attacker to boot a malicious software image or execute unsigned code and bypass the image verification check part of the secure boot process of an affected device. To exploit this vulnerability, the attacker would need to have unauthenticated physical access to the device or obtain privileged access to the root shell on the device.
