Falha em verificação de autorização

O software realiza uma verificação de autorização, mas a implementação está incorreta ou incompleta, permitindo que um atacante contorne as restrições de acesso pretendidas. O erro típico é lógica falha na verificação (condições mal formuladas, casos não tratados) ou confiança em dados do usuário para validar permissões.

Exemplo

Uma aplicação web valida se o usuário está autenticado, mas esquece de checar se ele tem permissão para acessar o recurso específico. Um atacante muda o ID do objeto na URL e acessa dados de outro usuário porque a aplicação não verifica propriedade ou role antes de retornar o conteúdo.

Como mitigar

Implemente verificações de autorização explícitas em todo ponto de acesso a recurso sensível, verificando não apenas quem é o usuário, mas se ele tem permissão específica para aquela ação. Use um modelo de controle de acesso bem definido (RBAC, ABAC) e teste sistematicamente casos de bypass (usuários não autorizados, escalação de privilégio, alteração de parâmetros).
