CVE-2024-40117Public exploitNetwork attack vector

Unauthenticated administrative access via exposed LAN page

Published Jul 26, 2024 · Updated Nov 11, 2024

Authentication bypass in Solar-Log 1000 Firmware before 2.8.2-52 allows remote attackers to obtain administrative privileges. The web administration server serves /lan.html without authentication, exposing administrative controls for LAN configuration. Network reachability alone is sufficient; successful access permits configuration-file changes and manipulation of system status.
