The NordVPN user-mode application allows a low-privileged attacker to act as a trusted process and connect to the named pipe \"\\\\.\\pipe\\nord-security\\v1\\NordVpnService\\Server\". The attacker can then invoke the \"ISettingsGrpc.StopService\" and \"ISettingsGrpc.ChangeServiceStartType\" methods with an arbitrary service name, allowing them to stop any unprotected Windows service and change its startup type. This leads to denial of service of critical system services. Services protected by Windows (PPL processes, Windows Tamper Protection), such as Windows Defender, cannot be stopped or reconfigured.\n\n\nThis issue was fixed in version 8.12\n\n## Affected\n\n- `NordVPN < 8.12`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":37,"depthScoreParts":{"impact":37.4,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
