나는 자동 도구가 **무들 버전에 영향을 미치는 취약점을 찾는 데 매우 쓸모없다는 것을 발견했다**. 당신은 **다음에서 확인할 수 있다**: [**https://snyk.io/vuln/composer:moodle%2Fmoodle**](https://snyk.io/vuln/composer:moodle%2Fmoodle)

## **RCE**

당신은 **관리자** 역할을 가져야 하며 **"사이트 관리"** 탭 안에 **플러그인을 설치할 수 있다**: 

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

관리자라면 여전히 **이 옵션을 활성화해야 할 수도 있다**. 무들 권한 상승 PoC에서 어떻게 하는지 볼 수 있다: [https://github.com/HoangKien1020/CVE-2020-14321](https://github.com/HoangKien1020/CVE-2020-14321).

그런 다음, **다음 플러그인을 설치할 수 있다**. 이 플러그인은 고전적인 pentest-monkey php r**ev shell**을 포함하고 있다 (_업로드하기 전에 압축을 풀고, revshell의 IP와 포트를 변경한 후 다시 압축해야 한다_)

또는 [https://github.com/HoangKien1020/Moodle_RCE](https://github.com/HoangKien1020/Moodle_RCE)에서 플러그인을 사용하여 "cmd" 매개변수를 가진 일반 PHP 셸을 얻을 수 있다.

악성 플러그인을 실행하려면 다음에 접근해야 한다:
```bash

```
