Conflito de Interpretação

Ocorre quando diferentes componentes de um sistema interpretam a mesma entrada, comando ou formato de dados de formas distintas, criando uma desconexão entre a intenção e o resultado. Um atacante explora essa divergência para contornar validações, executar ações não autorizadas ou injetar código malicioso.

Exemplo

Um firewall bloqueia requisições HTTP com 'union select' na query, mas o servidor backend interpreta sequências de espaços e comentários SQL de forma diferente do WAF. O atacante envia 'uni/**/on sel/**/ ect' que passa pelo filtro, mas o banco de dados executa como SQL injection completo.

Como mitigar

Normalize todas as entradas em um único ponto, antes de qualquer processamento, garantindo que validadores (WAF, parsers, bancos de dados) usem as mesmas regras. Implemente testes de integração que verifiquem se diferentes camadas interpretam dados idênticos da mesma maneira.
