Vulnerability Summary

Multiple local privilege escalation vulnerabilities have been identified in the LiquidVPN client up to and including 1.37 for macOS. An attacker can communicate with an unprotected XPC service and directly execute arbitrary OS commands as root or load a potentially malicious kernel extension because com.smr.liquidvpn.OVPNHelper uses the system function to execute the "tun_path" or "tap_path" pathname within a shell command.
