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.
* move password rules to Models\User::PASSWORD_RULES
* validate new password according to rules on password reset
* add password requirements info to auth.passwords.reset view
[BREAKING] — REMOVES REMOTE API
A new API will need to be implemented properly using the new Laravel
Passport OAuth2 system. DingoAPI was becoming too unstable and
development wasn’t really moving along enough to continue to rely on it.
Permission obtained from @DDynamic. Contributions from other users were
removed since we did not obtain permission from them for the re-license.
From this point forward all contributors must have a signed Contributor
License Agreement on file.
Cleaned up the code a bit, also checks TOTP before attemping to verify
user.
This addresses the potential for an attacker to try at a password
and/or confirm that the password is correct unless they have a valid
TOTP code for the request. A failed TOTP response will trigger a
throttle count on the login as well.
