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。
介绍
# ZeroLogon testing script
A Python script that uses the Impacket library to test vulnerability for the Zerologon exploit (CVE-2020-1472).
It attempts to perform the Netlogon authentication bypass. The script will immediately terminate when succesfully
performing the bypass, and not perform any Netlogon operations. When a domain controller is patched, the detection
script will give up after sending 2000 pairs of RPC calls and conclude the target is not vulnerable (with a
false negative chance of 0.04%).
## Installation
Requires Python 3.7 or higher and Pip. Install dependencies as follows:
pip install -r requirements.txt
Note that running `pip install impacket` should work as well, as long as the script is not broken by future Impacket
versions.
## Running the script
The script targets can be used to target a DC or backup DC. It likely also works against a read-only DC, but this has
not been tested. Given a domain controller named `EXAMPLE-DC` with a file containing a list of IP address `IPlist.txt`, run the script as follows:
./zerologon_tester.py EXAMPLE-DC IPlist.txt
The DC name should be its NetBIOS computer name. If this name is not correct, the script will likely fail with a
`STATUS_INVALID_COMPUTER_NAME` error.
A Whitepaper on this vulnerability will be published here: https://www.secura.com/blog/zero-logon on Monday 14 sept.
