What is an attack that seeks to attack a website, based on the website's trust of an authenticated user?

Cross-site request forgery (XSRF or CSRF) sends forged requests to a website, supposedly from a trusted user. Cross-site scripting (XSS) is the injection of scripts into a website to exploit the users. A buffer overflow tries to put more data in a variable than the variable can hold. A remote-access Trojan (RAT) is malware that gives the attacker access to the system.
