2. Potential Attack Vectors and Exploitation Methods

Reflected XSS vulnerabilities occur when an attacker injects malicious scripts into a web application, which are then reflected off a web server to the user's browser. Potential attack vectors include:

• Phishing Attacks: An attacker could craft a malicious URL and send it to a user, enticing them to click on it.
• Session Hijacking: By injecting scripts that steal session cookies, an attacker could hijack a user's session.
• Data Theft: Malicious scripts could be used to exfiltrate sensitive data from the user's browser.
• Defacement: Attackers could alter the content displayed on the web page.

Exploitation Methods:

• URL Manipulation: Injecting malicious scripts into URL parameters.
• Form Inputs: Submitting malicious scripts through form inputs.
• HTTP Headers: Injecting scripts into HTTP headers that are reflected back to the user.
