CVE-2020-3492

Name of the Vulnerable Software and Affected Versions: Cisco IOS XE Software for Cisco Catalyst 9800 Series Wireless Controllers and Cisco AireOS Software for Cisco Wireless LAN Controllers (WLC) (affected versions not specified)

Description: A vulnerability in the Flexible NetFlow Version 9 packet processor could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The issue is due to insufficient validation of certain parameters in a Flexible NetFlow Version 9 record. An attacker could exploit this by spoofing the address of an existing Access Point on the network and sending a Control and Provisioning of Wireless Access Points (CAPWAP) packet that includes a crafted Flexible NetFlow Version 9 record to an affected device, potentially causing a process crash that would lead to a reload of the device.

Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
