Hello! I just found some vulnerabilities after scanning a web using w3af, but there's a problem! Mayday! 
I don't know how to exploit these vulnerabilities, wich are:

• Shared hosting.
• CSRF vulnerability
• Path disclosure vulnerability
• Cookie without HttpOnly
• SVN user disclosure vulnerability
• XSS (In a image, WTF)
• US Social Security Number Disclosure

I need to know which of these vulnerabilities are the easiest to exploit because I'm training, and somehow I want to vulnerate this target, whatever it cost.
(I don't want to deface the site, only need to know how I can vulnerate some vulnerabilities of them)
Thanks people, I'm waiting for your response, it would be helpful for me. (please D:)
Bye
