Official description

A technique has been identified that adapts a known port-stealing method to Wi-Fi environments that use multiple BSSIDs. By leveraging the relationship between BSSIDs and their associated virtual ports, an attacker could potentially bypass inter-BSSID isolation controls. Successful exploitation may enable an attacker to redirect and intercept the victim's network traffic, potentially resulting in eavesdropping, session hijacking, or denial of service.

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.
