Golang 程序漏洞检测利器 govulncheck(二):漏洞数据库详解

上一篇文章详细介绍了 Golang 程序漏洞扫描工具 govulncheck 的使用方法,govulncheck 强大功能的背后,离不开 Go 漏洞数据库(Go vulnerability database)的支持,接下来详细讲解下 Go 漏洞数据库相关的知识。

Go 漏洞数据库(Go vulnerability database)是什么?

在当今数字化的世界中,软件安全是至关重要的。随着 Golang 在开发领域的日益流行,Go 项目的安全性也越来越重要。为了帮助开发者及时发现和解决与 Golang 相关的安全漏洞,Go 漏洞数据库应运而生。

Go 漏洞数据库(Go vulnerability database),访问地址是 https://vuln.go.dev 或者 https://pkg.go.dev/vuln,是一个存储 Golang 安全漏洞信息的数据库,由 Golang 官方维护。漏洞信息数据来自现有的源,例如 cve、ghsa 和 Go 包维护者直接提交的漏洞报告等,这些信息随后由 Go 安全团队审核并添加到数据库中。

该数据库支持多数据源访问,提供访问漏洞数据源的接口和默认实现。漏洞项使用 OSV(Open Source Vulnerability format)格式存储和传输。开发人员可以基于 module 的路径或者 ID 从漏洞数据库中查找是否存在已知漏洞。

Go 漏洞数据库 API

Go 漏洞数据库提供基于 HTTP 协议,请求方式为 GET 的一系列接口,每个接口都是返回 JSON 类型的数据。

  1. 获取数据库元数据接口 /index/db.json[.gz]

示例如下:

$ curl https://vuln.go.dev/index/db.json
{"modified":"2023-08-23T14:38:50Z"}
  1. 获取每个模块元数据接口 /index/modules.json[.gz]

示例如下:

$ curl https://vuln.go.dev/index/modules.json
[ {
  // The module path.
  "path": string,
  // The vulnerabilities that affect this module.
  "vulns":
    [ {
      // The vulnerability ID.
      "id": string,
      // The latest time the vulnerability should be considered
      // to have been modified, as an RFC3339-formatted UTC
      // timestamp ending in "Z".
      "modified": string,
      // (Optional) The module version (in SemVer 2.0.0 format)
      // that contains the latest fix for the vulnerability.
      // If unknown or unavailable, this should be omitted.
      "fixed": string,
    } ]
} ]
  1. 获取每个漏洞元数据接口 /index/vulns.json[.gz]

示例如下:

$ curl https://vuln.go.dev/index/vulns.json
[ {
     // The vulnerability ID.
     "id": string,
     // The latest time the vulnerability should be considered
     // to have been modified, as an RFC3339-formatted UTC
     // timestamp ending in "Z".
     "modified": string,
     // A list of IDs of the same vulnerability in other databases.
     "aliases": [ string ]
 } ]
  1. 获取某个漏洞信息接口 /ID/$id.json[.gz]

示例如下:

$ curl https://vuln.go.dev/ID/GO-2023-2003.json
{
    "schema_version": "1.3.1",
    "id": "GO-2023-2003",
    "modified": "2023-08-10T22:06:06Z",
    "published": "2023-08-10T22:06:06Z",
    "aliases": [
        "GHSA-8c37-7qx3-4c4p"
    ],
    "summary": "Blst fails to perform group signature validation",
    "details": "When complemented with a check for infinity, blst skips performing a signature group-check.

govulncheck 使用漏洞数据库方法

govulncheck 使用的漏洞数据地址是 https://vuln.go.dev,可以使用 -db 参数指定漏洞数据库,支持 http://、https:// 和 file:// 协议。指定的漏洞数据库必须实现上面讲解的几个 API。govulncheck 命令在从 http 源读取时使用 “.json.gz” 端点,而从文件源读取时,使用 “json”端点。
