CVE-2025-41678Network attack vector

Configuration database manipulation via SQL injection

Published Jul 21, 2025 · Updated Nov 3, 2025

SQL injection in MB connect line mbNET.mini and Helmholz REX 100 before 2.3.3 allows remote authenticated users to alter configuration data. The affected POST handler passes SQL special elements into a configuration-database statement without proper neutralization; no endpoint or parameter is published. High-privileged access is required, and successful injection permits configuration changes and can interrupt device availability.
