CVE-2022-40187 in Foresight GC3 Launch Monitor
Summary
by MITRE • 10/13/2022
Foresight GC3 Launch Monitor 1.3.15.68 ships with a Target Communication Framework (TCF) service enabled. This service listens on a TCP port on all interfaces and allows for process debugging, file system modification, and terminal access as the root user. In conjunction with a hosted wireless access point and the known passphrase of FSSPORTS, an attacker could use this service to modify a device and steal intellectual property.

The Foresight GC3 Launch Monitor system version 1.3.15.68 contains a critical security vulnerability that stems from an improperly configured Target Communication Framework service. This service operates as a debugging interface that remains active by default, creating an attack surface that allows unauthorized access to the device's core functionalities. The vulnerability exists because the TCF service listens on a TCP port across all network interfaces without proper authentication mechanisms, effectively providing a backdoor that can be exploited by malicious actors who gain network access to the device.
The technical flaw within this implementation represents a severe configuration error that violates fundamental security principles of least privilege and network segmentation. The service operates with root-level privileges, granting attackers complete control over the device's processes, file systems, and terminal access. This configuration creates a path for privilege escalation attacks where an attacker can execute arbitrary code, modify system files, and potentially exfiltrate sensitive data without requiring physical access to the device. The vulnerability is particularly concerning because it enables remote code execution capabilities that can be leveraged for persistent access to the system.
The operational impact of this vulnerability extends beyond simple unauthorized access, as it provides attackers with the capability to compromise intellectual property and manipulate device functionality. When combined with a hosted wireless access point and the known passphrase FSSPORTS, the attack vector becomes significantly more accessible to threat actors. This configuration allows for a complete compromise of the device's integrity, enabling attackers to modify firmware, steal proprietary data, and potentially use the device as a pivot point for accessing other systems within the network. The implications are particularly severe for golf course monitoring systems that may contain sensitive operational data or proprietary algorithms.
Security professionals should implement immediate mitigations including disabling the TCF service entirely, restricting network access to the device through firewall rules, and changing default credentials where possible. The vulnerability aligns with CWE-284, which addresses improper access control, and represents a clear violation of the principle of least privilege as outlined in the NIST Cybersecurity Framework. From an ATT&CK perspective, this vulnerability maps to multiple techniques including T1059 for command and scripting interpreter and T1078 for valid accounts, as attackers can leverage the root-level access to establish persistence. Organizations should conduct thorough network scans to identify affected devices and implement network segmentation to limit the potential impact of such vulnerabilities across their infrastructure.
