# Executando comandos arbitrários via Pacotes RPM
## Verificando o Ambiente
Para aproveitar este vetor, o usuário deve ser capaz de executar comandos yum como um usuário com privilégios mais altos, ou seja, root.

### Um exemplo funcional deste vetor
Um exemplo funcional deste exploit pode ser encontrado na sala [daily bugle](https://tryhackme.com/room/dailybugle) no [tryhackme](https://tryhackme.com).

## Empacotando um RPM
Na seção a seguir, abordarei como empacotar um shell reverso em um RPM usando [fpm](https://github.com/jordansissel/fpm).

O exemplo abaixo cria um pacote que inclui um gatilho antes da instalação com um script arbitrário que pode ser definido pelo atacante. Quando instalado, este pacote executará o comando arbitrário. Usei um exemplo simples de shell reverso netcat para demonstração, mas isso pode ser alterado conforme necessário.
