> 在SDL安全设计中，常常会做三方组件的CVE安全分析，基于这样的背景，决定开发一款能抓取CVE的数据并提供查询接口的程序。比如可以结合笔者的另一款工具[dcweb](https://github.com/he1m4n6a/dcweb)，就可以快速构建三方组件的安全扫描。

# 简介

CVE-DB 是一款抓取 https://nvd.nist.gov/  cve数据的工具，主要有两种功能：

1、抓取和更新cve数据保存在本地数据库

2、提供http接口查询cve数据

# 安装

```bash
CGO_ENABLED=0 GOARCH=amd64 GOOS=linux go build -a -o cve-db .
```

GOOS参数可以指定生成的二进制文件格式，包含三个平台选项：

- linux

- windows

- drawin

# 使用

## 命令行参数

1.获取帮助信息

```bash
$ ./cve-db -h
```

2.更新或者插入cve数据

```bash
$ ./cve-db -u
```

3.开启http服务器

```
$ ./cve-db -s
```

## 配置文件config.cfg

配置文件需要放在`/etc/config.cfg`路径下，如需修改到其他路径，可修改代码`config.go`第12行

```bash
const Path = "/etc/config.cfg"
```

配置文件样例：

```xml
DBEngine = mysql
DBServer = 127.0.0.1:3306
DBName  = cvedb
DBUser = root
DBPasswd = 123456
DebugSQL = false
Bind = 0.0.0.0
Port = 8000
HTTPProxy = 
Year = 2012
```

- 前面6个参数关于mysql的，开启`DebugSQL`会打印mysql执行过程。
- `Bind`和`Port`是配置服务器开启的地址和端口，默认监听`0.0.0.0:8000`
- HTTPProxy设置下载代理，格式eg：`http://proxy.example.com:8080`
- Year是配置从`哪一年`开始抓取`到至今`的cve漏洞，默认是从爬取所有数据（`2002`开始）

# httpserver接口

1.获取单个cve漏洞的信息

```bash
$ curl http://127.0.0.1:8000/cves/cve-2020-0003| jq "."
```

返回结果：
