Discrepância Observável em Respostas

A aplicação revela informações sensíveis através de diferenças detectáveis em seu comportamento, tempo de resposta ou mensagens de erro — por exemplo, retornando erros diferentes para usuário inexistente vs. senha incorreta. Um atacante pode explorar essas pistas para inferir dados confidenciais sem acesso direto.

Ejemplo

Um sistema de login que responde 'Usuário não encontrado' em 100ms, mas 'Senha incorreta' em 500ms (após validação). Um invasor enumera contas válidas medindo latência, ou identifica emails registrados pela velocidade da resposta.

Cómo mitigar

Padronize respostas de erro (mesma mensagem genérica), normalize tempos de execução com delays constantes, e evite vazar informações estruturais (ex: 'este email já existe'). Auditoria de logs e timestamps também revelar quem tentou enumerar dados sensíveis.
