This covers vulnerabilities where malicious people are able to gain system access and execute arbitrary code with the privileges of a local user.

Cross-Site Scripting

Different Cross-Site Scripting related vulnerabilities are also classified under this category, including "script insertion" and "cross-site request forgery".

Cross-Site Scripting vulnerabilities are often used against specific users of a website to steal their credentials or to conduct spoofing attacks.
