Official description

The Limit Login Attempts Security WordPress plugin before 3.4.1 does not enforce its two-factor authentication on every password-authentication route, so an attacker who already knows a protected user's password can authenticate through an alternative login interface and obtain that user's access without completing the second factor.

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.
