Aruba AOS-10 devices: attackers can bypass login on nearby network

Someone on the same local network as an affected Aruba AOS-10 device could skip the login check. They could then gain full admin control of the device and change its settings or read sensitive data.

How the attack works simplified

  1. 1Adjacent attackerAttacker is on the local network
  2. 2PAPI protocolAttacker reaches the management protocol
  3. 3Auth bypassedLogin controls are circumvented
  4. 4Admin accessAttacker gets administrative control
  5. ResultAttacker controls the network device

What happened

Authentication bypass flaws in the PAPI management protocol of Aruba AOS-10 network devices allow an unauthenticated adjacent attacker to circumvent authentication controls.

Why it is dangerous: An attacker who gets onto the local network could take over network controllers or gateways, change configurations, and access or tamper with sensitive data. Organizations running AOS-10 Aruba network infrastructure are at risk.

Are you affected?

You are affected if you run Aruba AOS-10 devices with the PAPI protocol reachable from networks where an attacker could be present.

Aruba AOS-10 (specific versions not stated in the available material)

What to do

  1. Check the official HPE/Aruba security bulletin for affected AOS-10 versions and the patched release
  2. Update AOS-10 devices to the fixed version as soon as possible
  3. Restrict access to the PAPI management protocol to trusted management networks until patched
