description

NoMachine nxhtd web-service deployments are affected by a server-side request forgery caused by insufficient URI validation. An unauthenticated remote attacker may cause the service to make requests using its service-account context. Exposure requires network access to the nxhtd web service, which uses port 4443 by default.

mitigation

Restrict network access to the nxhtd web-service port, including the default port 4443, to trusted clients only. Disable the NoMachine web interface where it is not required.
