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
# zeroscan
Zeroscan is a Domain Controller vulnerability scanner, that currently includes checks for Zerologon (CVE-2020-1472), MS-PAR/MS-RPRN and SMBv2 Signing.
<br>
**CVE-2020-1472:**
Uses a built-in script to check for Zerologon (CVE-2020-1472), but does NOT attempt to exploit the target, it is simply a vulnerability scanner.
Codebase borrowed from: https://github.com/SecuraBV/CVE-2020-1472
<br>
**MS-PAR / MS-RPRN:**
Uses a wrapper around Impacket's rpcdump to check if the print services MS-PAR and MS-RPRN are remotely accessible. This check may help to determine if the target is vulnerable to CVE-2021-1675.
<br>
**SMBv2 Signing:**
Uses a wrapper around the Nmap Scripting Engine (NSE) script 'smb2-security-mode', to identify the target's SMBv2 signing configuration.
<br>
<br>
**Installation:**
git clone https://github.com/NickSanzotta/zeroscan.git
cd zeroscan/
virtualenv -p /usr/bin/python3.9 venv
source venv/bin/activate
python3 -m pip install -r requirements.txt
**Menu:**
```
Zeroscan
--------------------------------------------------
Usage:
python3 zeroscan.py -t dc01 192.168.1.10
python3 zeroscan.py -iL /path/to/targetfile.txt
python3 zeroscan.py -iL /path/to/targetfile.txt --database
python3 zeroscan.py -iL /path/to/targetfile.txt --drop-table
python3 zeroscan.py -iL /path/to/targetfile.txt -r
python3 zeroscan.py -iL /path/to/targetfile.txt -v
Primary options:
-t TARGET TARGET Single target using netbiosname and ipaddress. I.e "dc01 192.168.1.10"
-iL TARGETSFILE File that contains one target per line using netbiosname and ipaddress. I.e "dc01 192.168.1.10"
Secondary options:
--database DATABASE Filepath for database file.
--drop-table Drops database table.
-r, --rpc-message Turn on RPC response messages for CVE-2020-1472, helpful when troubleshooting connectivity issues.
-v, --verbose Turn on verbosity, helpful when debugging code.
-h, --help Show this help message and exit.
```
**Sample Output:**
