The purpose of output encoding (as it relates to Cross Site Scripting) is to convert untrusted input into a safe form where the input is displayed as data to the user without executing as code in the browser. The following charts provides a list of critical output encoding methods needed to stop Cross Site Scripting.

Cross-Site Scripting (XSS) attacks are a type of injection, in which malicious scripts are injected into otherwise benign and trusted websites. XSS attacks occur when an attacker uses a web application to send malicious code, generally in the form of a browser side script, to a different end user.

The best way to fix DOM based cross-site scripting is to use the right output method (sink). For example if you want to use user input to write in a div tag element don't use innerHtml , instead use innerText or textContent .

foo='+document.cookie</script>'. This attack causes the victim’s session ID to be sent to the attacker’s website, allowing the attacker to hijack the user’s current session. Note: Attackers can use XSS to defeat any automated Cross-Site Request Forgery (CSRF) defense the application might employ.

The very first OWASP Cheat Sheet, Cross Site Scripting Prevention, was inspired by RSnake's work and we thank RSnake for the inspiration! Tests. This cheat sheet demonstrates that input filtering is an incomplete defense for XSS by supplying testers with a series of XSS attacks that can bypass certain XSS defensive filters.

IMPORTANT: Remember that Cross-Site Scripting (XSS) can defeat all CSRF mitigation techniques! See the OWASP XSS Prevention Cheat Sheet for detailed guidance on how to prevent XSS flaws. First, check if your framework has built-in CSRF protection and use it
