ArubaOS access points are vulnerable to gateway impersonation attacks when clients connect via wired or wireless interfaces, allowing unauthenticated attackers to redirect network traffic into a man-in-the-middle position. An attacker can exploit address-based spoofing to intercept or modify data streams intended for the legitimate gateway, compromising the confidentiality of client communications. No patch is currently available.
