Official description
The Admin Classic Bundle provides a Backend UI for Pimcore. `AdminBundle\Security\PimcoreUserTwoFactorCondition` introduced in v11 disable the two factor authentication for all non-admin security firewalls. An authenticated user can access the system without having to provide the two factor credentials. This issue has been patched in version 1.2.2.

The underlying weakness: Use of Single-factor Authentication
The product uses an authentication algorithm that uses a single factor (e.g., a password) in a security context that should require more than one factor.
How developers prevent this class of flaw
- Use multiple independent authentication schemes, which ensures that -- if one of the methods is compromised -- the system itself is still likely safe from compromise. For this reason, if multiple schemes are possible, they should be implemented and required -- especially if they are easy to use.
