Official description

Unauthenticated Denial-of-Service (DoS) vulnerabilities exist in the CLI service accessed via the PAPI protocol. Successful exploitation of these vulnerabilities result in the ability to interrupt the normal operation of the affected access point.

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.
