CVE-2025-41646Network attack vector

Unauthenticated device compromise via boolean password coercion

Published Jun 6, 2025 · Updated Jun 6, 2025

Authentication bypass in KUNBUS Revolution Pi webstatus 2.4.5 and earlier allows remote attackers to fully compromise the device. The password check implicitly converts the JSON TRUE value supplied in the hashcode password parameter, treating it as a successful authentication. No credentials or user interaction are required; successful access exposes the application's device-configuration and service-control functions.
