v0.5.1 (Bodacious Boreopterus)

Fixed

• Fixes a bug that allowed a user to bypass 2FA authentication if using the correct username and password for an account.

Security Disclosure:

This bug was reported to us by a user (@Ferry#1704) on Discord on
Monday, November 7th, 2016.

It was disclosed that it was possible to bypass the 2FA checkpoint by
clicking outside of the modal which would prompt the modal to close,
but not submit the form. The user could then press the login button
which would trigger an error. Due to this error being triggered the
authentication attempt was not cancelled. On the next page load the
application recognized the user as logged in and continued on to the
panel.

At no time was it possible to login without using the correct email
address and password.

As a result of this bug we have re-factored the Authentication code for
logins to address the persistent session. Previously accounts were
manually logged back out on 2FA failure. However, as this bug
demonstrated, causing a fatal error in the code would prevent the
logout code from firing, thus preserving their session state.

This commit modifies the code to use a non-persistent login to handle
2FA checking. In order for the session to be saved the application must
complete all portions of the login without any errors, at which point
the user is persistently authenticated using Auth::login().

This resolves the ability to cause an exception and bypass 2FA
verification.

We would like to thank Ferry for the responsible and timely disclosure of this security bug. If you believe you have found such a bug, please do not hesitate to get in contact with us on Discord, or by emailing us support@pterodactyl.io.
