High

VectorAV:A/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions: Cisco IOS XE Wireless Controller Software for the Cisco Catalyst 9000 Family (affected versions not specified)
Description: A vulnerability in the WLAN Local Profiling feature could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device. The issue is due to incorrect parsing of HTTP packets while performing HTTP-based endpoint device classifications. An attacker could exploit this by sending a crafted HTTP packet to an affected device, potentially causing it to reboot and resulting in a DoS condition.
Recommendations: For Cisco IOS XE Wireless Controller Software for the Cisco Catalyst 9000 Family, update to a version that includes the software updates released by Cisco to address this vulnerability. As a temporary workaround, consider disabling the WLAN Local Profiling feature, as it is disabled by default, to minimize the risk of exploitation.
