Falhas do tipo CWE-250

Execução com privilégios desnecessários

A aplicação ou processo executa com mais permissões (root, admin, service account privilegiado) do que realmente precisa para suas funções. Quando explorada, uma vulnerabilidade no código ganha acesso elevado, permitindo ao atacante comprometer todo o sistema ou dados sensíveis que só aquele nível de privilégio poderia acessar.

Exemplo

Um serviço web que apenas lê arquivos de configuração e envia emails roda como root. Uma injeção SQL nesse serviço não daria acesso apenas ao banco de dados, mas permitiria ao atacante criar usuários do SO, desabilitar firewalls ou acessar qualquer arquivo do servidor.

Como mitigar

Execute sempre com o menor nível de privilégio necessário — crie contas de serviço dedicadas e sem permissões administrativas. Revise regularmente as permissões de cada processo ou daemon em produção e remova acessos que não são estritamente usados.
