CVE-2019-5421

Plataformatec Devise version 4.5.0 and earlier, using the lockable module contains a CWE-367 vulnerability in The `Devise::Models::Lockable` class, more specifically at the `#increment_failed_attempts` method. File location: lib/devise/models/lockable.rb that can result in Multiple concurrent requests can prevent an attacker from being blocked on brute force attacks. This attack appear to be exploitable via Network connectivity - brute force attacks. This vulnerability appears to have been fixed in 4.6.0 and later.

Mediante la utilización del módulo bloqueable, Plataformatec Devise, en versiones 4.5.0 y anteriores, contiene una vulnerabilidad CWE-367 en la clase "Devise::Models::Lockable", más específicamente en el método "#increment_failed_attempts". La ubicación del archivo lib/devise/models/lockable.rb, que puede resultar en peticiones múltiples concurrentes, puede impedir que un atacante sea bloqueado durante ataques de fuerza bruta. Este ataque parece ser explotable mediante la conectividad de red y ataques de fuerza bruta. Esta vulnerabilidad parece haber sido solucionada en versiones 4.6.0 y posteriores.
