Detection Guidance

[{'type': 'paragraph', 'content': 'The vulnerability can be detected by testing the endpoint `/node/kudaby/nodeFN/procedure` for reflected Cross-Site Scripting (XSS) through multiple parameters. This involves sending crafted HTTP requests with script payloads in the parameters and observing if the scripts are reflected and executed in the HTTP response.'}, {'type': 'paragraph', 'content': 'Common detection methods include using web vulnerability scanners or manual testing with tools like curl or browser developer tools to inject test scripts and verify their reflection.'}, {'type': 'list_item', 'content': "Example curl command to test for reflected XSS: curl -i -X GET 'http://<target>/node/kudaby/nodeFN/procedure?param=<script>alert(1)</script>'"}, {'type': 'list_item', 'content': 'Use browser developer tools to inspect the HTTP response for reflected script tags or payloads.'}] [1]
