CVE-2025-12176Network attack vector

Administrative access via undocumented onboard accounts

Published Oct 24, 2025 · Updated Oct 24, 2025

Undocumented accounts in Azure Access BLU-IC2 and BLU-IC4 1.19.5 and earlier allow remote attackers to obtain administrative controller access. The firmware creates undocumented administrative accounts to let onboard applications access controller functions, but the vendor does not disclose the account names, credentials, or affected interface. Network reachability is the published gate; no prior privileges or user interaction are required, and compromise can affect controller data, configuration, and availability.
