Intermediário não intencional ('Deputado confuso')

Ocorre quando um componente com privilégios é induzido a executar ações em nome de um atacante, sem validar adequadamente se a solicitação veio realmente de quem deveria autorizar. O código confia em identificadores fracos ou contexto incompleto, permitindo que um terceiro abuse da autoridade do componente para acessar recursos ou realizar operações que não conseguiria fazer diretamente.

Ejemplo

Um serviço web interno que processa solicitações de eliminação de arquivos verifica se o usuário está autenticado, mas não valida se a solicitação veio do próprio usuário ou de um terceiro (ex: injeção de referência cruzada ou CSRF). Um atacante induz o navegador da vítima a fazer um pedido de deleção usando os cookies da vítima, e o serviço executa a ação porque reconhece a autenticação, não a origem legítima.

Cómo mitigar

Implemente validação robusta da origem e integridade da solicitação: use tokens CSRF únicos e vinculados à sessão, valide o header Referer/Origin, e aplique autenticação step-up para operações sensíveis. Nunca confie apenas em cookies ou sessão para operações de risco; exija confirmação explícita do usuário ou re-autenticação.
