Patch this week

Critical severity: a successful attack would have severe impact.

What to do

  1. Check which version of ArubaOS (AOS) you run against the affected versions below, and install the vendor's latest release.
  2. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

Authentication bypass vulnerabilities in the affected interface of AOS-10 could allow an unauthenticated remote attacker to run arbitrary commands on the underlying host if certain preconditions outside of the attacker's control are met. Successful exploitation could allow an attacker to execute arbitrary commands on the underlying operating system.

The underlying weakness: Authentication Bypass Using an Alternate Path or Channel

The product requires authentication, but the product has an alternate path or channel that does not require authentication.

How developers prevent this class of flaw

  • Funnel all access through a single choke point to simplify how users can access a resource. For every access, perform a check to determine if the user has permissions to access the resource.
