Confiança inadequada em mecanismo de proteção implementado no cliente

O servidor delega para o cliente (navegador, app, dispositivo) a responsabilidade de implementar uma proteção que deveria ser garantida no servidor. Isso é perigoso porque o cliente está sob controle do atacante — qualquer validação, restrição ou lógica de segurança implementada apenas no lado do cliente pode ser contornada, alterada ou removida. O servidor fica vulnerável quando assume que o cliente vai cumprir as regras.

Example

Um e-commerce que valida limite de quantidade de compra apenas no JavaScript do frontend, ou um banco que confere crédito disponível apenas no navegador antes de enviar a transação. Um atacante modifica o código do cliente, remove a validação ou faz requisições diretas ao servidor, contornando a proteção completamente.

How to mitigate

Implemente toda validação, autenticação e autorização críticas no servidor. Nunca confie em mecanismos de segurança executados apenas no cliente. Use validação no cliente para UX, mas sempre revalide e reforce as regras no backend antes de qualquer operação sensível.
