In this 3rd part of our XSS series, we explore the practical aspects of identifying XSS vulnerabilities in web applications.Recognizing potential entry points for XSS involves spotting common patterns of insecure coding and insufficient input/output handling.Manual testing techniques include testing for reflected XSS, stored XSS, and DOM-based XSS using different contexts and payloads.Automated tools such as Burp Suite, OWASP ZAP, XSS Hunter, DalFox, and XSStrike can also be used to detect XSS vulnerabilities.
