IXON VPN Client before 1.4.4 on Linux and macOS allows Local Privilege Escalation to root because there is code execution from a configuration file that can be controlled by a low-privileged user. There is a race condition in which a temporary configuration file, in a world-writable directory, can be overwritten.

  • VDE-2025-042Lenze: VPN Client Privilege Escalation in combination with Lenze x500 IoT Gateway2025-05-27csaf · lenze_psirtDE

    The Lenze VPN client is vulnerable to a Local Privilege Escalation to root/SYSTEM by executing a configuration file which can be controlled by a non-privileged user. This occurs through a race condition exploit, where an attacker can overwrite the temporary OpenVPN configuration file located in a world-writable directory. By injecting malicious commands into the configuration file prior to its execution by the VPN client, an attacker can trigger arbitrary code execution with root/system privileges when a VPN connection is initiated. The vulnerability has been remediated in the version 1.4.4 of the Lenze VPN client. Due to some further developments and completion of the functional scope, it is recommended to update the firmware of the x500 IoT Gateway devices immediately, regardless of the current security vulnerability in the VPN client.
