Cisco IOS XE Software Arbitrary Code Execution Vulnerability

A vulnerability in Cisco IOS XE Software could allow an authenticated, local attacker to execute persistent code at boot time and break the chain of trust. This vulnerability is due to incorrect validations by boot scripts when specific ROM monitor (ROMMON) variables are set. An attacker could exploit this vulnerability by installing code to a specific directory in the underlying operating system (OS) and setting a specific ROMMON variable. A successful exploit could allow the attacker to execute persistent code on the underlying OS. To exploit this vulnerability, the attacker would need access to the root shell on the device or have physical access to the device.

Cisco IOS XE Software 操作系统命令注入漏洞

Cisco IOS XE Software是美国思科（Cisco）公司的一个操作系统。用于企业有线和无线访问，汇聚，核心和WAN的单一操作系统，Cisco IOS XE降低了业务和网络的复杂性。 Cisco IOS XE Software 中存在操作系统命令注入漏洞，该漏洞源于设置了特定的ROM监视器（ROMMON）变量时启动脚本对验证的不正确所致，该漏洞允许攻击者通过将代码安装到基础操作系统（OS）中的特定目录并设置特定的ROMMON变量来利用此漏洞。
