Descriptions

A vulnerability in the London Trust Media Private Internet Access (PIA) VPN Client v82 for macOS could allow an authenticated, local attacker to run arbitrary code with elevated privileges. The openvpn_launcher binary is setuid root. This program is called during the connection process and executes several operating system utilities to configure the system. The networksetup utility is called using relative paths. A local unprivileged user can execute arbitrary commands as root by creating a networksetup trojan which will be executed during the connection process. This is possible because the PATH environment variable is not reset prior to executing the OS utility.

Una vulnerabilidad en el cliente VPN de Private Internet Access (PIA) de London Trust Media para macOS, podría permitir a un atacante local autenticado ejecutar código arbitrario con privilegios elevados. El binario openvpn_launcher es root setuid. Este programa se llama durante el proceso de conexión y ejecuta varias utilidades del sistema operativo para configurar el sistema. La utilidad networksetup se llama mediante rutas (path) relativas. Un usuario local sin privilegios puede ejecutar comandos arbitrarios como root mediante la creación de un troyano networksetup que se ejecutará durante el proceso de conexión. Esto es posible porque la variable de entorno PATH no se restablece antes de ejecutar la utilidad del sistema operativo.
