Official description

Filament is a collection of full-stack components for accelerated Laravel development. Prior to versions 4.12.0 and 5.7.0, incorrect challenge-form required-field handling allows app-based multi-factor authentication to be bypassed when recovery codes are enabled. Email-based multi-factor authentication is not affected. This issue is fixed in versions 4.12.0 and 5.7.0.

The underlying weakness: Improper Authentication

When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.

How developers prevent this class of flaw

  • Use an authentication framework or library such as the OWASP ESAPI Authentication feature.
