FKIE_CVE-2024-9050

Vulnerability from fkie_nvd - Published: 2024-10-22 13:15 - Updated: 2024-12-18 17:15
Severity ?
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
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.

En esta configuraci\u00f3n, compuesta por un formato clave-valor, el complemento no puede escapar caracteres especiales, lo que lleva a la aplicaci\u00f3n a interpretar los valores como claves. Uno de los par\u00e1metros m\u00e1s cr\u00edticos que un usuario malintencionado podr\u00eda abusar es la clave `leftupdown`. Esta clave toma un comando ejecutable como valor y se utiliza para especificar lo que se ejecuta como una devoluci\u00f3n de llamada en NetworkManager-libreswan para recuperar los ajustes de configuraci\u00f3n de nuevo a NetworkManager. Como NetworkManager utiliza Polkit para permitir que un usuario sin privilegios controle la configuraci\u00f3n de red del sistema, un actor malintencionado podr\u00eda lograr una escalada de privilegios local y una posible ejecuci\u00f3n de c\u00f3digo como root en la m\u00e1quina de destino."
