Unauthenticated log disclosure via persistent web link
Published Feb 27, 2024 · Updated Mar 24, 2025
Information disclosure in GL.iNet router firmware allows remote attackers on the local network to download exported logs without authentication. The export-log interface writes lograd.tar under /tmp and links it as /www/js/logread.tar, leaving the archive web-accessible after logout; OpenVPN configuration export has the same flaw. Access requires local-network reachability, and successful exploitation discloses logs or VPN configuration data without altering the device.
