CVE-2025-12217Network attack vector

Unauthenticated SNMP access via default community string

Published Oct 25, 2025 · Updated Oct 25, 2025

Default SNMP credentials in Azure Access Technology BLU-IC2 and BLU-IC4 through 1.19.5 allow remote attackers to query the SNMP service. The embedded SNMP agent accepts the factory community string public as authentication instead of requiring a device-specific secret. Network reachability to SNMP is sufficient; the vendor has not disclosed which objects are readable or writable, so the precise data and control impact is unspecified.
