Unauthenticated resource modification and disruption via authentication bypass
Published Sep 1, 2026 · Updated Sep 2, 2026
Authentication bypass in Hewlett Packard Enterprise AOS-CX allows remote attackers to modify protected resources and interrupt services. HPE has not disclosed which AOS-CX authentication control is faulty or what operation incorrectly accepts unauthenticated input. Reachability requires adjacent-network access to the switch; successful exploitation has no reported confidentiality impact but can alter resources and cause limited service disruption.
