CVE-2025-37165Network attack vector

Network configuration disclosure via unintended packet exposure

Published Jan 13, 2026 · Updated Jan 13, 2026

Information disclosure in HPE Networking Instant On Access Points 3.0.0.0 through 3.3.1.0 allows remote attackers to read VLAN details. In router mode, affected access points place internal VLAN configuration details into packets visible on unintended network interfaces. No authentication or user interaction is required; exploitation depends on access to inspect the affected packets and exposes configuration data without changing it.
