Execução de código ou comandos não autorizados

Fraqueza em que a aplicação executa código ou comandos sem validar adequadamente a origem, permissões ou conteúdo fornecido por um atacante. O perigo está em permitir que um usuário sem privilégios execute operações restritas, como comandos do sistema, funções administrativas ou código arbitrário, comprometendo toda a segurança da aplicação.

Ejemplo

Um painel de controle que permite ao usuário executar scripts de manutenção sem autenticação apropriada, ou uma função que passa entrada do usuário diretamente para eval() em Python/JavaScript, permitindo injeção de código malicioso que roda com as permissões da aplicação.

Cómo mitigar

Implemente validação rigorosa de entrada, use allowlists (não blacklists), mantenha controle de acesso baseado em roles (RBAC) com verificação em cada operação sensível, e evite construtores dinâmicos como eval(). Quando precisar executar comandos do sistema, use APIs seguras e nunca passe entrada do usuário sem sanitização completa.
