How does Cross-Site Scripting (XSS) attack differ from CSRF?

XSS involves injecting malicious scripts into web applications, while CSRF impersonates end users to perform actions unknowingly.

XSS manipulates XML data, while CSRF manipulates HTML data.

XSS attacks the server, while CSRF attacks the client.

XSS requires authentication credentials, while CSRF does not.

What is the goal of directory traversal attacks?

To access or edit files/folders beyond the intended directory

Which protocol is targeted in LDAP Injection attacks?
