Summary

IXON VPN Client before 1.4.4 on Windows allows Local Privilege Escalation to SYSTEM 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.
