Aruba AOS-8 flaw lets outsiders run commands as root

Attackers on the network can get past the login check on an affected Aruba AOS-8 device and run commands on it with full control. That means they could take over the whole device.

How the attack works simplified

  1. 1Remote attackerNo login credentials needed
  2. 2Vulnerable interfaceReachable over the network
  3. 3Authentication bypassedLogin checks are skipped
  4. 4Commands executedArbitrary commands run on host
  5. ResultAttacker gains root control of device

What happened

Vulnerabilities in an AOS-8 network-facing interface allow unauthenticated remote attackers to bypass authentication and execute arbitrary commands as root on the underlying operating system.

Why it is dangerous: A successful attacker gets complete control of the device, which can lead to full compromise of the network equipment and everything routed through it. Any organization running an exposed AOS-8 device is at risk.

Are you affected?

You are affected if you run an Aruba AOS-8 device with the vulnerable interface reachable over the network.

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

What to do

  1. Check whether your Aruba AOS-8 devices are running the vulnerable interface and restrict access to it from untrusted networks
  2. Check the vendor's security advisory for the patched AOS-8 version and update as soon as one is available
  3. Review device logs for unexpected logins or command activity
