Security Vulnerabilities - CVEs Published In September 2022
A vulnerability in the processing of malformed Common Industrial Protocol (CIP) packets that are sent to Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to unexpectedly reload, resulting in a denial of service (DoS) condition. This vulnerability is due to insufficient input validation during processing of CIP packets. An attacker could exploit this vulnerability by sending a malformed CIP packet to an affected device. A successful exploit could allow the attacker to cause the affected device to unexpectedly reload, resulting in a DoS condition.

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.

A vulnerability in the self-healing functionality of Cisco IOS XE Software for Embedded Wireless Controllers on Catalyst Access Points could allow an authenticated, local attacker to escape the restricted controller shell and execute arbitrary commands on the underlying operating system of the access point. This vulnerability is due to improper checks throughout the restart of certain system processes. An attacker could exploit this vulnerability by logging on to an affected device and executing certain CLI commands. A successful exploit could allow the attacker to execute arbitrary commands on the underlying OS as root. To successfully exploit this vulnerability, an attacker would need valid credentials for a privilege level 15 user of the wireless controller.
