CVE-2025-2121Public exploit

Adjacent-network arbitrary file write via missing authorization

Published Mar 9, 2025 · Updated Mar 10, 2025

Improper access control in THINKWARE F800PRO 20250226 allows remote attackers to write arbitrary files over the dashcam's Wi-Fi network. The file-storage interface accepts attacker-supplied files without enforcing write authorization, including files containing malware. The attacker must first join the dashcam's local Wi-Fi network; the public report does not establish code execution or any further authentication requirement.
