CriticalVulnerabilityCVE-2026-79861updated 25 Oct 2026, 16:50 UTC

Aruba AOS-10 network devices can be taken over remotely without login

Attackers can send specially crafted network messages to certain AOS-10 Aruba devices and run their own commands on them, with no password needed. That gives them full control of the device, which could be used to spy on or disrupt the netw

How the attack works simplified

  1. 1Attacker sends packetsCrafted PAPI packets sent over the network
  2. 2Device reachedNo authentication required to send packets
  3. 3Command injectedUnsanitized input is passed to a system command
  4. 4Code runs as rootRuns with privileges of the underlying OS
  5. ResultAttacker controls the network device

What happened

A command injection flaw in Aruba AOS-10 lets an unauthenticated attacker send crafted PAPI packets to execute arbitrary code as a privileged user on the underlying operating system.

Why it is dangerous: Successful exploitation gives attackers privileged control of the network device, enabling traffic interception, lateral movement into internal networks, and disruption of connectivity. Organizations running AOS-10 wireless or switching infrastructure exposed to untrusted networks are at highest risk.

Are you affected?

You are affected if you run Aruba AOS-10 devices in your network; the affected product versions are not specified in the available material.

What to do

  1. Check the Aruba security advisory for AOS-10 and identify your exact affected versions
  2. Apply the vendor-provided patch or firmware update as soon as it is available
  3. Restrict access to PAPI traffic and limit management interfaces to trusted networks until patched
