Descriptions

Nginx-UI is a web interface to manage Nginx configurations. It is vulnerable to arbitrary command execution by abusing the configuration settings. The `Home > Preference` page exposes a list of system settings such as `Run Mode`, `Jwt Secret`, `Node Secret` and `Terminal Start Command`. While the UI doesn't allow users to modify the `Terminal Start Command` setting, it is possible to do so by sending a request to the API. This issue may lead to authenticated remote code execution, privilege escalation, and information disclosure. This vulnerability has been patched in version 2.0.0.beta.9.

Nginx-UI es una interfaz web para administrar configuraciones de Nginx. Es vulnerable a la ejecución de comandos arbitrarios al abusar de los ajustes de configuración. La página `Home > Preferences` expone una lista de configuraciones del sistema como `Run Mode`, `Jwt Secret`, `Node Secret` y `Terminal Start Command`. Si bien la interfaz de usuario no permite a los usuarios modificar la configuración del "Terminal Start Command", es posible hacerlo enviando una solicitud a la API. Este problema puede provocar la ejecución remota de código autenticado, escalada de privilegios y divulgación de información. Esta vulnerabilidad ha sido parcheada en la versión 2.0.0.beta.9.
