CVE-2022-45227Network attack vector

Unauthenticated backup file exposure

Published Dec 12, 2022 · Updated Apr 23, 2025

Directory listing exposure in Dragino Lora LG01 18ed40 IoT v4.3.4 allows remote attackers to download a backup file without authentication. The web portal exposes the /lib/ directory and serves a backup artifact through that unauthenticated listing. Any network-reachable portal permits confidentiality loss through retrieval of the exposed file; no integrity or availability impact is reported.
