CVE-2024-42470Public exploitNetwork attack vector

Unauthenticated config disclosure via unprotected REST endpoints

Published Aug 9, 2024 · Updated Aug 9, 2024

Missing authorization in openHAB WebUI's CometVisu add-on before 4.2.1 allows remote attackers to read or modify hidden configuration data. ConfigResource exposes /rest/cv/config/hidden and related configuration methods without requiring an authenticated user, returning stored entries such as service credentials. Network access to the openHAB HTTP service and an installed CometVisu add-on are sufficient; exposed secrets and settings can be read or altered.
