CveMonitor

0x01 功能说明

通过搜索功能,在github搜索cve关键字,对最近15分钟内结果进行处理,对比出新增POC,并通过钉钉/飞书进行通知(在lib/Notice.py中修改机器人token)

使用说明:

➜  python3 cveMonitor.py
2022-07-25 15:10:02	Github总数量:968
2022-07-25 15:10:02	SELECT * FROM Monitor WHERE gitname = 'blmvuln' and giturl = 'https://github.com/MathiasReker/blmvuln' and status = '1'
2022-07-25 15:10:02	SELECT * FROM monitor WHERE status = '1' and hash = 'f0e0d9e7ab1087621ced54bacf4276f49ef25762'
2022-07-25 15:10:02	SELECT * FROM black
2022-07-25 15:10:02	INSERT INTO main.monitor('cve','gitname','giturl','description','hash','status') VALUES('cve-2022-31101','blmvuln','https://github.com/MathiasReker/blmvuln','Major Security Vulnerability on PrestaShop Websites - CVE-2022-31101','f0e0d9e7ab1087621ced54bacf4276f49ef25762','1')
2022-07-25 15:10:03	SELECT * FROM monitor WHERE cve = 'cve-2022-31101' and status = '1'

【CVE新增监控告警通知:】
[0] 项目名称:blmvuln
[0] 项目地址:https://github.com/MathiasReker/blmvuln
[0] 项目描述: Major Security Vulnerability on PrestaShop Websites - CVE-2022-31101
[0] CVE编号:CVE-2022-31101
[0] CVSS等级:8.8 HIGH
[0] CVE说明:prestashop/blockwishlist is a prestashop extension which adds a block containing the customer's wishlists. In affected versions an authenticated customer can perform SQL injection. This issue is fixed in version 2.1.1. Users are advised to upgrade. There are no known workarounds for this issue.

服务器设置定时任务,10分钟执行一次py(由于要减少github访问量,因此针对20分钟前新增的数据不会进行处理,只要设置的执行周期<20分钟就可以了,推荐是5-15)

➜ crontab -l
*/5 * * * *  cd /root/tools/CveMonitor/ && python3 cveMonitor.py  2>&1  >> out.txt
