Fix

Am I affected? Yes if you run HPE Aruba Networking wireless AOS on Mobility Conductors, Mobility Controllers, Mobility Gateways or access points at: - AOS-10: 10.3.0.0 through 10.8.1.1 - AOS-8: 8.10.0.0 through 8.13.3.0 The October 22, 2026 bulletin fixes 72 CVEs. Eight are rated CVSS 10.0 (including CVE-2026-79844, an authentication bypass in AOS-10 that can lead to code execution), and most of the flaws need no login. Several sit in the PAPI management protocol on UDP 8211. HPE said it knew of no public exploit code or attacks when it published the bulletin. That usually changes quickly after a large networking-gear patch. How to check: - On the device CLI: show version. In Aruba Central, the device inventory lists the firmware version per controller and gateway. Fix: upgrade to a fixed release on your branch, or later: - AOS-10: 10.8.1.2, 10.7.2.7 or 10.4.1.14 - AOS-8: 8.13.3.1 or 8.10.0.24 Branches outside these (older or end-of-support trains) should move to one of these supported lines. Interim mitigation (until upgraded): - Keep PAPI (UDP 8211) unreachable from untrusted networks; it should only be open between your own controllers and APs. - Put the CLI and web management interfaces on a dedicated management VLAN or layer 2 segment, and/or allow them only from admin hosts with firewall policy. - Turn on logging and accounting for management access, and send the logs to a central server. After upgrading: - Confirm show version on every conductor, controller and gateway; cluster members can be left on the old image. - Review admin accounts, management logins and configuration changes from before the upgrade. If anything looks unfamiliar, rotate admin passwords, RADIUS/TACACS shared secrets and API tokens.
