一、漏洞详情
Microsoft Remote Registry Service（远程注册表服务）是Windows操作系统中的一个服务，允许远程用户通过网络访问和修改计算机上的注册表。
近日，监测到Microsoft Remote Registry Service特权提升漏洞（CVE-2024-43532）。该漏洞源于Microsoft Remote Registry客户端在SMB传输不可用的情况下回退到RPC（远程过程调用）认证时，切换到较旧的协议（如TCP/IP）并采用弱认证级别（RPC_C_AUTHN_LEVEL_CONNECT），该级别无法验证通信的完整性或来源，攻击者可利用该缺陷，通过拦截NTLM 身份验证握手并将其中继到其他服务（如ADCS），实现NTLM中继攻击，进而可能创建域管理员账户或接管整个域。
建议受影响用户做好资产自查以及预防工作，以免遭受黑客攻击。
