CVE-2024-23942

Device impersonation via cleartext configuration credentials

Published Mar 18, 2025 · Updated Aug 20, 2025

Cleartext storage in MB connect line products before 2.16.2 or 8.2.0 allows local users to obtain device credentials. When a device serial number is unknown before the portal creates a downloadable configuration, the file remains unencrypted and exposes sensitive data. A local low-privileged user with file access can impersonate the device or block the legitimate device from the cloud portal, interrupting service.
