Autenticação insuficiente contra falsificação de identidade

Ocorre quando o mecanismo de autenticação falha em validar corretamente a identidade do usuário ou cliente, permitindo que um atacante se passe por outra pessoa. A implementação não implementa verificações robustas (como criptografia, assinaturas digitais ou desafios aleatórios), deixando a autenticação vulnerável a spoofing.

Example

Um sistema de API que valida usuários apenas pelo campo 'nome de usuário' em um cabeçalho HTTP sem usar token, sessão ou assinatura criptográfica — um atacante altera o header e acessa dados de outros usuários. Ou um protocolo que aceita certificados autoassinados sem verificar a cadeia de confiança, autenticando servidores falsos.

How to mitigate

Use mecanismos de autenticação estabelecidos e testados: tokens JWT com assinatura, OAuth 2.0, ou mTLS. Sempre valide criptograficamente a identidade do cliente, nunca confie em cabeçalhos ou cookies não assinados. Implemente desafios multi-fator e revogue credenciais comprometidas rapidamente.
