Traffic interception via client-isolation policy bypass
Published Mar 4, 2026 · Updated Mar 4, 2026
Client-isolation bypass in HPE Aruba Networking Wireless Operating Systems allows attackers to redirect client traffic at Layer 3. The client isolation mechanism fails to preserve Layer 2 communication restrictions when attacker-controlled traffic is redirected through Layer 3. Adjacent-network access is required, and bidirectional interception additionally depends on a port-stealing attack.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
