2. Potential Attack Vectors and Exploitation Methods

Cross-site scripting (XSS) vulnerabilities allow attackers to inject malicious scripts into web pages viewed by other users. Potential attack vectors include:

• Stored XSS: Malicious scripts are permanently stored on the target server (e.g., in a database) and executed when the page is loaded.
• Reflected XSS: Malicious scripts are reflected off a web server, such as in an error message or search result.
• DOM-based XSS: The vulnerability exists in the client-side code rather than the server-side code.

Exploitation methods may involve:

• Session Hijacking: Stealing user session cookies to impersonate users.
• Credential Theft: Capturing user credentials through keylogging or form manipulation.
