CVE-2023-20268

Cisco Access Point Software Uncontrolled Resource Consumption Vulnerability

Published Sep 27, 2023 CVSS 3.1 · 4.7 Medium EPSS < 1% KEV · Not listed

Description

A vulnerability in the packet processing functionality of Cisco access point (AP) software could allow an unauthenticated, adjacent attacker to exhaust resources on an affected device. 

This vulnerability is due to insufficient management of resources when handling certain types of traffic. An attacker could exploit this vulnerability by sending a series of specific wireless packets to an affected device. A successful exploit could allow the attacker to consume resources on an affected device. A sustained attack could lead to the disruption of the Control and Provisioning of Wireless Access Points (CAPWAP) tunnel and intermittent loss of wireless client traffic.
