Mitigation checklist
- To reduce exposure, restrict network access to the FreeRDP server to trusted clients only. Configure firewall rules to limit incoming connections to the RDP port (typically 3389) from known and authorized IP addresses or subnets. If the FreeRDP server is not essential, consider disabling the service to prevent exploitation. Any changes to firewall rules or service status may require a service restart to take effect.
