CriticalVulnerabilityCVE-2026-79862updated 25 Oct 2026, 16:50 UTC

Aruba AOS-10 and AOS-8 devices can be taken over by nearby attackers

A flaw in certain Aruba network controller software lets someone nearby, without logging in, send specially crafted data that can run their own code on the device. The attacker could then gain full control of the underlying system.

How the attack works simplified

  1. 1Nearby attackerSits on the adjacent network, no login needed
  2. 2Crafted data sentOversized data sent to the affected interface
  3. 3Buffer overflowMemory overrun lets injected code execute
  4. 4Privileged code runsCode runs as privileged user on the OS
  5. ResultAttacker controls the controller

What happened

Buffer overflow vulnerabilities in an interface of Aruba AOS-10 and AOS-8 allow unauthenticated adjacent attackers to execute arbitrary code with privileges on the underlying operating system.

Why it is dangerous: An attacker who can reach the affected interface from the local network could fully control the device, potentially exposing or disrupting the wireless and network traffic it manages.

Are you affected?

You are affected if you run Aruba AOS-10 or AOS-8 network controllers or gateways 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 the exact affected AOS-10 and AOS-8 versions and install the fixed release
  2. Restrict access to the affected interface so only trusted networks can reach it until patched
  3. Monitor device logs for unusual activity or unexpected processes
