Conflito de Interpretação

Fraqueza em que diferentes componentes de um sistema interpretam a mesma entrada ou dado de forma diferente, causando inconsistência lógica. Um atacante explora essa divergência para contornar validações em um componente enquanto consegue efeito diferente em outro, comprometendo a segurança geral.

Example

Um firewall valida uma URL como segura interpretando-a de uma forma, mas o navegador a interpreta diferentemente e acessa um endpoint malicioso. Ou um validador servidor rejeita um caminho com '..' enquanto outro componente o normaliza de forma distinta, permitindo path traversal.

How to mitigate

Padronize a interpretação: use bibliotecas de parsing e normalização comuns entre todos os componentes, valide em múltiplas camadas com a mesma lógica, e teste casos de borda onde diferentes interpretadores possam divergir (encoding, caracteres especiais, formatos ambíguos).
