CVE-2026-23812Public exploit

Traffic interception via gateway MAC impersonation

Published Mar 4, 2026 · Updated Mar 4, 2026

Security boundary bypass in HPE Aruba Networking AOS-8 and AOS-10 allows remote attackers to intercept traffic via gateway MAC spoofing. An associated client can use the gateway's MAC address, causing internal forwarding state to direct victim uplink frames to the attacker's Wi-Fi link. The attacker must join an affected wired or wireless client network; the resulting position exposes traffic intended for the legitimate gateway.
