Official description

A vulnerability has been identified in the web-based management interface of AOS-CX switches that could potentially allow an unauthenticated remote actor to circumvent existing authentication controls. In some cases this could enable resetting the admin password.

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

The underlying weakness: Improper Authentication

When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.

How developers prevent this class of flaw

  • Use an authentication framework or library such as the OWASP ESAPI Authentication feature.
