Detailsinfo

A vulnerability was found in Cisco Catalyst 9100 (version now known). It has been rated as critical. This issue affects some unknown processing of the component 802.11 Association Frame Handler. The manipulation with an unknown input leads to a buffer overflow vulnerability. Using CWE to declare the problem leads to CWE-120. The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow. Impacted is availability. The summary by CVE is:

A vulnerability in the 802.11 association frame validation of Cisco Catalyst 9100 Series Access Points (APs) could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient input validation of certain parameters within association request frames received by the AP. An attacker could exploit this vulnerability by sending a crafted 802.11 association request to a nearby device. An exploit could allow the attacker to unexpectedly reload the device, resulting in a DoS condition.

The weakness was released 10/01/2022 as cisco-sa-ap-assoc-dos-EgVqtON8. The advisory is shared at tools.cisco.com. The identification of this vulnerability is CVE-2022-20945 since 11/02/2021. Neither technical details nor an exploit are publicly available.
