Execução com privilégios desnecessários

É quando um programa ou processo roda com mais permissões do que precisa para executar suas funções normais. Se esse programa for comprometido, o atacante herda todos esses privilégios extras, ampliando drasticamente o dano possível. É o oposto do princípio do menor privilégio.

Ejemplo

Um daemon web que deveria apenas servir arquivos estáticos roda como root ao invés de um usuário específico sem privilégios. Se a aplicação web tiver uma vulnerabilidade de RCE, o invasor já está dentro com acesso total ao sistema, podendo alterar qualquer arquivo ou iniciar ataques laterais.

Cómo mitigar

Implemente o princípio do menor privilégio: crie contas de serviço dedicadas com apenas as permissões necessárias, use drop privileges em runtime quando possível, configure containers e VMs com usuários não-root, e revise regularmente quais recursos cada aplicação realmente precisa acessar.
