Description

Multiple local privilege escalation vulnerabilities have been identified in the LiquidVPN client through 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.

Weakness classification

  • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
