CVE-2025-12219Network attack vector

Unauthenticated controller and connected-system compromise

Published Oct 25, 2025 · Updated Oct 25, 2025

Vulnerable components in Azure Access OS through 1.19.5 allow remote attackers to compromise BLU-IC2 and BLU-IC4 controllers. Azure Access Technology has not identified the affected components, their unsafe operation, or the attack input that reaches them. The network path requires no authentication or user interaction; successful exploitation grants read and write access and can interrupt controller and connected-system operation.
