CVE-2025-55051Network attack vector

Device compromise via default credentials

Published Sep 9, 2025 · Updated Sep 10, 2025

Default credentials in Baicells NOVA430e/430i, NOVA436Q, NEUTRINO430, and NOVA846 allow remote attackers to compromise devices. INCD has not disclosed the credential, exposed interface, or authentication operation that accepts the unchanged default value. Network reachability and possession of the default credential are required; successful access permits device data access, modification, and service interruption.
