### CVEs

Eu descobri que as ferramentas automáticas são bastante **inúteis para encontrar vulnerabilidades que afetam a versão do moodle**. Você pode **verificar** por elas em [**https://snyk.io/vuln/composer:moodle%2Fmoodle**](https://snyk.io/vuln/composer:moodle%2Fmoodle)

## **RCE**

Você precisa ter o papel de **gerente** e você **pode instalar plugins** dentro da aba **"Administração do site"**: 

![](<../../images/image (630).png>)

Se você for gerente, pode ainda precisar **ativar esta opção**. Você pode ver como no PoC de escalonamento de privilégios do moodle: [https://github.com/HoangKien1020/CVE-2020-14321](https://github.com/HoangKien1020/CVE-2020-14321).

Então, você pode **instalar o seguinte plugin** que contém o clássico rev shell php do pentest-monkey (_antes de enviá-lo, você precisa descompactá-lo, mudar o IP e a porta do revshell e compactá-lo novamente_)

{{#file}}
moodle-rce-plugin.zip
{{#endfile}}

Ou você poderia usar o plugin de [https://github.com/HoangKien1020/Moodle_RCE](https://github.com/HoangKien1020/Moodle_RCE) para obter um shell PHP regular com o parâmetro "cmd".

Para acessar e lançar o plugin malicioso, você precisa acessar:
```bash
http://domain.com/<moodle_path>/blocks/rce/lang/en/block_rce.php?cmd=id
```
