CVE-2024-9050

A flaw was found in the libreswan client plugin for NetworkManager (NetkworkManager-libreswan), where it fails to properly sanitize the VPN configuration from the local unprivileged user. In this configuration, composed by a key-value format, the plugin fails to escape special characters, leading the application to interpret values as keys. One of the most critical parameters that could be abused by a malicious user is the `leftupdown`key. This key takes an executable command as a value and is used to specify what executes as a callback in NetworkManager-libreswan to retrieve configuration settings back to NetworkManager. As NetworkManager uses Polkit to allow an unprivileged user to control the system's network configuration, a malicious actor could achieve local privilege escalation and potential code execution as root in the targeted machine by creating a malicious configuration.

Summary
  • (es) Se encontró una falla en el complemento de cliente de libreswan para NetworkManager (NetkworkManager-libreswan), donde no puede desinfectar correctamente la configuración de VPN del usuario local sin privilegios. En esta configuración, compuesta por un formato clave-valor, el complemento no puede escapar caracteres especiales, lo que lleva a la aplicación a interpretar los valores como claves. Uno de los parámetros más críticos que un usuario malintencionado podría abusar es la clave `leftupdown`. Esta clave toma un comando ejecutable como valor y se utiliza para especificar lo que se ejecuta como una devolución de llamada en NetworkManager-libreswan para recuperar los ajustes de configuración de nuevo a NetworkManager. Como NetworkManager utiliza Polkit para permitir que un usuario sin privilegios controle la configuración de red del sistema, un actor malintencionado podría lograr una escalada de privilegios local y una posible ejecución de código como root en la máquina de destino.
