How the attack works simplified

  1. 1Nearby attackerWithin Wi-Fi radio range, no login needed
  2. 2Crafted Wi-Fi framesFrames sent to the AOS-10 access point
  3. 3Frame processing flawDevice leaks sensitive information
  4. 4Information retrievedUsed to reach network services or disrupt them
  5. ResultSensitive data exposed to nearby attacker

What happened

A sensitive information disclosure vulnerability exists in the Wi-Fi frame processing of Aruba AOS-10, reachable by an unauthenticated attacker within radio range.

Why it is dangerous: An attacker could obtain information usable for further access to network services supported by AOS-10, or interrupt normal operation of the affected service. Organizations running AOS-10 wireless infrastructure are at risk.

Are you affected?

You are affected if you run Aruba AOS-10 wireless infrastructure with a vulnerable version.
