Bypassing Google's Two-Factor Authentication

An anonymous reader writes "The team at Duo Security figured out how to bypass Google's two-factor authentication, abusing Google's application-specific passwords. Curiously, this means that application-specific passwords are actually more powerful than users' regular passwords, as they can be used to disable the second factor entirely to gain control of an account. Duo [publicly released this exploit Monday] after Google fixed this last week — seven months after initially replying that this was expected behavior!"

It's a privilege escalation problem. The surprise was that changing your main password or password recovery email should be only done by the full account, not an ASP context.
