CVID,全称为CVE Vulnerability Information Downloader,即CVE漏洞信息下载器,该工具支持从NIST(CVSS)、first.org(EPSS)和CISA下载信息,并将它们合并为一个列表。除此之外,该工具还可以利用来自OpenVAS等漏洞扫描程序的报告信息来丰富漏洞数据,以确定修复的优先级。该工具还包含了一个PowerBI模板,以丰富数据的查看形式。
通用漏洞评分系统(CVSS)是一个自由开放的行业标准,用于评估计算机系统安全漏洞的严重性。而漏洞预测评分系统(EPSS)用于估计软件漏洞在野被利用的可能性。CISA则主要负责发布已知漏洞列表。
CVID可以从上述三个漏洞信息来源下载信息,并组合成一个列表,并使用PowerBI等工具将漏洞扫描程序的结果与脚本在存储库中下载的信息相结合。该工具支持输出JSON和CSV格式数据,并将其存储到SQLite数据库中。
广大研究人员可以使用下列命令将该项目源码克隆至本地:

1、获取一个NIST API密钥:【https://nvd.nist.gov/developers/request-an-api-key】;
2、复制env_example.env文件;
3、编辑.env文件并添加API密钥;
4、可选:编辑docker-compose文件并调整cron计划任务;
5、可选:编辑data/vulnerability-tables-logstash/config/logstash.conf文件;
6、运行命令:docker-compose up -d;
7、脚本执行完后就可以在data/vulnerability-tables-cron/output/中查看到输出文件了;
我们可以直接执行下列命令来运行工具脚本:
docker exec -it vulnerability-tables-cron bash /opt/scripts/download.sh

该项目包含了一个个带有PowerBI模板文件的演示文件夹。它可以生成一个仪表盘,我们可以根据自己的需要进行调整:
OpenVAS报告必须采用csv格式才能导入工作:
PowerBI将使用创建的CVE.json文件并创建一个关系:
工具运行之后,将会生成一些输出文件:
316K CISA_known_exploited.csv
452K CISA_known_exploited.json
50M CVSS.csv
179M CVSS.json
206M CVE.json
56M CVE.csv
6.7M EPSS.csv
12M EPSS.json
49M database.sqlite
其中可以查看到针对每一个CVE漏洞的详细信息:
