CVE-2025-12218Network attack vector

Unauthorized controller access via default credentials

Published Oct 25, 2025 · Updated Oct 25, 2025

Default credentials in Azure Access Technology BLU-IC2 and BLU-IC4 1.19.5 and earlier allow remote attackers to access the controllers. The embedded firmware accepts vendor-set credentials for authentication, but the vendor does not identify the affected account, credential value, or interface. Network reachability to the undisclosed authentication service is required; successful use grants only the privileges assigned to the default account.
