Verificação insuficiente de autenticidade de dados

É quando o software aceita dados sem validar adequadamente se vieram de uma fonte legítima e confiável. O sistema confia em informações (mensagens, arquivos, requisições) sem confirmar sua origem ou integridade, permitindo que um atacante forje, modifique ou injete dados maliciosos que serão processados como se fossem legítimos.

Ejemplo

Um serviço aceita atualizações de configuração via JSON sem verificar assinatura digital ou token HMAC. Um atacante intercepta a requisição e modifica o payload para redirecionar logs para um servidor controlado por ele — e o serviço aplica a mudança porque 'recebeu um JSON válido'.

Cómo mitigar

Implemente autenticação criptográfica de dados: use assinatura digital (HMAC, RSA, ECDSA) ou tokens com validade (JWT com chave secreta), valide sempre a origem da mensagem antes de processar, e recuse dados sem prova de autenticidade. Não confie apenas em formato válido ou canal de transporte — valide origem e integridade.
