CriticalVulnerabilityCVE-2026-79863updated 25 Oct 2026, 16:50 UTC

Aruba AOS-10 and AOS-8 devices can be hijacked over the local network

A flaw in certain network devices lets someone nearby, without a password, send crafted data that takes control of the device. An attacker could then run their own commands with full administrator rights on the device.

How the attack works simplified

  1. 1Nearby attackerOn the same local network segment
  2. 2Crafted data sentSent to the affected device interface
  3. 3Buffer overflowMemory overrun lets code be injected
  4. 4Code executionRuns as privileged OS user
  5. ResultAttacker controls the network device

What happened

A buffer overflow in an interface of Aruba AOS-10 and AOS-8 allows unauthenticated arbitrary code execution as a privileged user on the underlying operating system, reachable from an adjacent network.

Why it is dangerous: Taking over the device could let an attacker disrupt or spy on network traffic and reach other systems, affecting everyone who depends on the network.

Are you affected?

You are affected if you run Aruba AOS-10 or AOS-8 network devices with the affected interface reachable from an adjacent network.

Aruba AOS-10 and AOS-8 (specific versions not stated in the provided material)

What to do

  1. Check the vendor advisory for patched AOS-10 and AOS-8 versions and update to them
  2. Restrict access to the affected interface so only trusted networks can reach it
  3. Monitor devices for unexpected behavior or configuration changes until patched
