Confiança em mecanismo de segurança implementado no cliente

O servidor delega a responsabilidade de uma proteção de segurança para o cliente executar, assumindo que ele vai cumprir. Isso é perigoso porque um atacante controla o cliente e pode simplesmente ignorar, contornar ou desabilitar essa proteção, deixando o servidor vulnerável.

Ejemplo

Um servidor web que valida permissões de acesso apenas via JavaScript no navegador, sem verificar novamente no backend. Um atacante desabilita o JavaScript ou intercepta a requisição, acessando dados que não deveria.

Cómo mitigar

Implemente toda validação crítica de segurança no servidor, nunca confie em verificações feitas apenas no cliente. O cliente pode fazer validação por UX, mas o servidor deve sempre validar independentemente autenticação, autorização, entrada de dados e regras de negócio.
