Atribuição Incorreta de Privilégios

Quando um sistema concede permissões ou privilégios a um usuário, processo ou recurso de forma inadequada — maior que o necessário ou para a entidade errada. Isso permite que atacantes escalem privilégios ou acessem dados/funcionalidades que não deveriam ter.

Ejemplo

Um aplicativo web cria uma pasta temporária com permissões 777 (leitura, escrita e execução para todos), ou um serviço Windows roda como SYSTEM quando deveria rodar como usuário comum. Outro cenário: uma função administrativa fica acessível via URL sem validação, permitindo qualquer usuário logado executá-la.

Cómo mitigar

Aplique o princípio do menor privilégio: conceda apenas as permissões mínimas necessárias. Use ACLs restritivas, validação de roles/permissões em cada função sensível, execute serviços com contas de baixo privilégio, e mantenha auditoria de mudanças de permissões.
