graphql攻击思路

了解

GraphQL 是一种由 Facebook 开发的用于 API 查询语言和运行时的数据查询语言。它允许客户端指定所需的数据结构和内容，从而有效地获取多个资源的数据。相比于传统的 RESTful API，GraphQL 具有更灵活的特性，客户端可以按需获取特定字段的数据，而不是在每个端点上预定义的数据结构。

可以直接看数据包，更能直观的了解graphql，比如hackerone就是用的graphql

请求：

代码语言：javascript复制
POST /graphql HTTP/2
Host: hackerone.com
Cookie: 
Content-Length: 341
Sec-Ch-Ua: "Google Chrome";v="119", "Chromium";v="119", "Not?A_Brand";v="24"
X-Csrf-Token: 
Sec-Ch-Ua-Mobile: ?0
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/119.0.0.0 Safari/537.36
Content-Type: application/json
X-Product-Feature: details
Accept: */*
X-Product-Area: reports
Sec-Ch-Ua-Platform: "Windows"
Origin: https://hackerone.com
Sec-Fetch-Site: same-origin
Sec-Fetch-Mode: cors
Sec-Fetch-Dest: empty
Referer: 
Accept-Encoding: gzip, deflate, br
Accept-Language: zh-CN,zh;q=0.9

{"operationName":"AppQuery","variables":{"product_area":"reports","product_feature":"details"},"query":"query AppQuery {n  maintenance_banner {n    idn    start_atn    end_atn    __typenamen  }n  session {n    idn    __typenamen  }n  me {n    idn    unreadNotificationCount: unread_notification_countn    __typenamen  }n}n"}

operationName我的理解是请求名，比如登录、查询之类的功能标识名称

variables就是参数，类似查询的范围{“product_area”:”reports”,”product_feature”:”details”}，查询的参数和返回包的数据对应 query查询的数据

代码语言：javascript复制
query AppQuery {
    maintenance_banner {
        id
        start_at
        end_at
        __typename
    }
    session {
        id
        __typename
    }
    me {
        id
        unreadNotificationCount: unread_notification_count
        __typename
    }
}

响应：

代码语言：javascript复制

识别graphql

/graphql /graphql/console /graphql.php /graphiql.php /explorer /altair /playground

字典

https://github.com/danielmiessler/SecLists/blob/master/Discovery/Web-Content/graphql.txt

ffuf语句

代码语言：javascript复制
ffuf -w graphql.txt -u https://target/FUZZ

可以使用Nuclei来检测GraphQL接口

模板可以使用如下:

https://github.com/projectdiscovery/nuclei-templates/blob/master/technologies/graphql-detect.yaml

代码语言：javascript复制
#单个目标
nuclei -t graphql-detect.yaml -u https://example.com 

# 多目标
nuclei -t graphql-detect.yaml -l target_domains.txt

指纹识别

可以使用: https://github.com/dolevf/graphw00f

代码语言：javascript复制
python3 main.py -f -d -t http://localhost:5000

或者burp搜索graphql接口

工具

graphql有一个内省模式，查询payload,.没启用返回就会报错

https://gist.github.com/craigbeck/b90915d49fda19d5b2b17ead14dcd6da

代码语言：javascript复制
	{
  __schema {
    types {
      name
    }
  }
}

OR:

代码语言：javascript复制
{
  __schema{
    queryType
    {
    name
    }
    
    mutationType {
      name
              }
  subscriptionType {
    name 
    }
    
    types{
      ...FullType
      }
      
      directives{
        name 
        description
         locations
          args{
            ...InputValue
            }
            }
        }
  }
        
        fragment FullType on __Type {
          kind 
          name
           description
            fields(includeDeprecated:true){
              name 
              description
               args{
                 ...InputValue
                 }
                 
                 type{
                   ...TypeRef
                   }
                   isDeprecated 
                   deprecationReason
                   }
                   
                   inputFields{
                     ...InputValue
                     }
                     
                     interfaces{
                       ...TypeRef
                       }
                       
                       enumValues(includeDeprecated:true){
                         name 
                         description
                          isDeprecated
                           deprecationReason
                           }
                           
                    possibleTypes{
                      ...TypeRef
                    }
                    }
        fragment InputValue on __InputValue{
          name 
          description
           type{
             ...TypeRef
             }
          defaultValue
          }
          
          
        fragment TypeRef on __Type{
          kind 
          name 
          ofType{
            kind 
            name 
            ofType{
              kind
               name 
               ofType {
                kind
                name
                ofType{
                     kind 
                     name 
                     ofType{
                       kind 
                       name 
                       ofType{
                         kind 
                         name 
                         ofType{
                           kind
                          name
                          }}}}}}}}

存在内省可以使用工具进行扫描：

Burp-InQL进行分析

浏览器插件Altair GraphQL Client https://chrome.google.com/webstore/detail/altair-graphql-client/flnheeellpciglgpaodhkhmapeljopja

自动化测试 https://github.com/dolevf/graphql-cop

没有内省可以用工具进行爆破扫描：

https://github.com/nikitastupin/clairvoyance

clairvoyance 扫描出来会有一个json文件，可以用 vovager进行分析 https://graphql-kit.com/graphql-voyager/

生成文档用于检索 2fd/graphdoc: Static page generator for documenting GraphQL Schema (github.com)
