I know some basics of DOM-based XSS. I know I have to look for Sources and Sinks if I want to detect DOM-based XSS.

I heard/read at various contexts that DOM based XSS is caused by untrusted client side input and developers need to follow instructions at the OWASP “DOM based XSS Prevention Cheat Sheet” in order to mitigate it.
OWASP mentions the following example of code vulnerable to a DOM based XSS attack:
Select your language:
<select><script>
document.write(“<OPTION value=1>”+document.location.href.substring(document… Continue reading How do browsers handle document.write in this DOM based XSS case?

Can the difference between reflected XSS and DOM XSS be explained using real world examples?
For example, how is it possible to exploit or grab a remote victim’s cookies or session related information?
From I understand with reflected XSS, JavaScript injection is used.
For example:
<script src="https://serveraddress/">filenae.js</script>
Is the same methodology used to exploit DOM based XSS?
