Adjacent traffic interception via inter-BSSID port stealing
Published Mar 4, 2026 · Updated Mar 4, 2026
Isolation bypass in HPE Aruba Networking Wireless Operating System AOS-8 and AOS-10 allows physically proximate attackers to redirect Wi-Fi traffic. HPE describes the mechanism as port stealing that leverages BSSID-to-virtual-port relationships after MAC address spoofing, but it does not disclose the responsible function or packet-processing operation. The attack requires a multi-BSSID network with Client Isolation enabled; redirected traffic supports eavesdropping and session hijacking.
