中文描述:
Cisco IOS XE SD-WAN Software是美国思科(Cisco)公司的一款应用于Cisco IOS XE 网络操作系统的用于网络管理(软件定义网络)的软件。 Cisco IOS XE SD-WAN Software 存在安全漏洞,该漏洞源于在受影响设备上的 bootflash 目录存在文件系统保护不足。攻击者可利用该漏洞执行任意命令覆盖存储在引导flash目录中的安装程序文件。
英文描述:
A vulnerability in the Cisco IOS XE SD-WAN Software CLI could allow an authenticated, local attacker to elevate privileges and execute arbitrary code on the underlying operating system as the root user. An attacker must be authenticated on an affected device as a PRIV15 user. This vulnerability is due to insufficient file system protection and the presence of a sensitive file in the bootflash directory on an affected device. An attacker could exploit this vulnerability by overwriting an installer file stored in the bootflash directory with arbitrary commands that can be executed with root-level privileges. A successful exploit could allow the attacker to read and write changes to the configuration database on the affected device.
