Official description

A vulnerability exists in the ArubaOS bootloader on 7xxx series controllers which can result in a denial of service (DoS) condition on an impacted system. A successful attacker can cause a system hang which can only be resolved via a power cycle of the impacted controller.

Source: the CVE record as published by its numbering authority, via NVD and CVE.org.

The underlying weakness: Uncontrolled Resource Consumption

The product does not properly control the allocation and maintenance of a limited resource.

How developers prevent this class of flaw

  • Ensure that protocols have specific limits of scale placed on them.
  • Ensure that all failures in resource allocation place the system into a safe posture.
