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。
