The attack is actually stored in some method to be later executed.
A malicious hacker would be much more devious to this type of security vulnerability.
There are many, many different methods to test for XSS vulnerabilities. If the output is correctly encoded, then instead of executed the tags, they would be html encoded and not cause the vulnerability Contact us for additional consulting services in product testing and/or training.
