CVE-2025-2122Public exploit

Owner connection denial via single-session exhaustion

Published Mar 9, 2025 · Updated Mar 10, 2025

Denial of service in the Connection Handler in THINKWARE F800PRO 20250226 allows remote attackers to block the owner’s connection. The device accepts only one connected client, so an attacker who joins first occupies the sole session and prevents the legitimate owner from connecting. Reachability requires access to the dashcam’s local network; the documented consequence is loss of owner access rather than a device crash.
