dracutdevs dracut是dracutdevs组织开源的一个事件驱动的 initramfs 基础设施。 dracutdevs dracut存在命令注入漏洞，该漏洞源于die()错误处理函数在initramfs紧急挂钩目录下写入shell脚本时未正确进行shell引用，当消息包含来自DHCP ROOT_PATH选项的数据时，可能允许相邻网络的攻击者控制恶意DHCP服务器注入命令替换序列，导致以root权限执行命令。

Vulnerability Title
Dracut: dracut: root code execution via unescaped error message written to sourced emergency hook script in die()
来源: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in dracut. The die() error-handling function writes its message into a shell script under the initramfs emergency-hook directory without properly shell-quoting it. When the message contains data derived from the DHCP ROOT_PATH option, an attacker on the adjacent network who controls a rogue DHCP server can inject a command-substitution sequence that executes as root the next time dracut sources its emergency hook scripts during standard boot-failure handling.
