CVE-2024-43532｜Microsoft Remote Registry Service特权提升漏洞（POC）

0x00 引言

Windows 操作系统中包含一项名为 Microsoft Remote Registry Service（远程注册表服务）的功能，允许用户通过网络远程访问和管理目标系统的注册表内容。

0x01 漏洞概述

该漏洞的成因在于，当 Microsoft Remote Registry 客户端检测到 SMB 传输不可用时，会自动回退至使用 RPC（远程过程调用）进行认证，并切换到较旧的通信协议（如 TCP/IP），同时采用较低的安全认证级别（RPC_C_AUTHN_LEVEL_CONNECT）。此认证级别无法确保通信的完整性或身份真实性，导致攻击者可借此漏洞拦截 NTLM 身份验证过程，并将认证凭据中继至其他服务（例如 ADCS），从而实施 NTLM 中继攻击。通过该方式，攻击者可能非法创建域管理员账户，甚至完全控制整个域环境。
