# Windows WinSock 辅助函数驱动程序特权提升漏洞
## 概述
Windows Ancillary Function Driver for WinSock (afd.sys) 中存在一个权限提升漏洞。攻击者可以利用此漏洞将权限从低权限用户提升到系统权限。
## 影响版本
- Windows 10, Version 2004
- Windows 10, Version 20H2
- Windows 10, Version 21H1
- Windows 10, Version 21H2
- Windows 11, Version 21H2
- Windows 11, Version 22H2
## 细节
此漏洞存在于Windows Ancillary Function Driver (afd.sys) 中,由于对某些输入参数的处理不当,攻击者可以通过精心构造的API调用来触发该漏洞。攻击者需要在一个低权限用户环境中运行恶意代码,以利用此漏洞提升权限。
## 影响
攻击者成功利用此漏洞后,可以从低权限用户提升到系统权限,从而有权限执行任何特权操作,包括但不限于安装程序、查看、更改或删除数据,以及创建拥有完全用户权限的新账户。
