Technical description

A vulnerability in the handling of encrypted wireless frames of Cisco Aironet Access Point (AP) Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on the affected device.

This vulnerability is due to incomplete cleanup of resources when dropping certain malformed frames. An attacker could exploit this vulnerability by connecting as a wireless client to an affected AP and sending specific malformed frames over the wireless connection. A successful exploit could allow the attacker to cause degradation of service to other clients, which could potentially lead to a complete DoS condition.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
