CVE-2018-18857
Multiple local privilege escalation vulnerabilities have been identified in the LiquidVPN client through 1.37 for macOS.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.60%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
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 "command_line" parameter as a shell command.
