0x01 漏洞描述
Windows TCP/IP 组件中发现了一个整数下溢漏洞,可能会触发缓冲区溢出。未经身份验证的远程攻击者可以通过发送特制的 IPv6 数据包到目标Windows系统机器导致目标蓝屏崩溃,精心构造请求理论上存在远程代码执行的可能性。该漏洞影响了所有受 IPv6 支持的 Windows 版本,包括即将发布的 Windows 11 版本 24H2。禁用 IPv6 的系统不受此漏洞的影响,但对于启用 IPv6 的系统,存在很大的利用风险。

0x03 漏洞复现

首先,看了我macos PD中的windows版本,完美符合:
复现步骤:
下载poc:
git clone https://github.com/ynwarcs/CVE-2024-38063.git
进入script目录:
cd CVE-2024-38063/script
修改脚本:
vim cve-2024-38063.py
下载依赖:
pip3 install scapy
直接干:
python3 cve-2024-38063.py
修改后的脚本如下:
iface指定攻击机用于发包的网卡,ip_addr是目标机器的ipv6地址,mac_addr是目标机的mac地址,留空,除非脚本提示找不到目标的mac地址才指定,num_tries和num_batches可以决定发多少个包,发的包越多越有可能触发蓝屏,原来这两个值均为20,在我的环境中未触发蓝屏改为50。
脚本运行截图:
POC复现就是这样,脚本小子的自娱自乐,把windows干到蓝屏重启。。。。。。
