CVE-2024-23943Network attack vector

Unauthenticated cloud API access via missing authentication

Published Mar 18, 2025 · Updated Mar 18, 2025

Missing authentication in the data24 service in affected MB connect line products allows remote attackers to access the cloud API. The bundled service exposes a critical cloud API function without authenticating requests, but the vendor has not identified the endpoint or operation. Network reachability is sufficient; access permits reading and modifying device or service data, while availability is not affected.
