CVE-2022-20695Network attack vector

Administrator access via flawed password validation

Published Apr 15, 2022 · Updated Nov 6, 2024

Authentication bypass in Cisco Wireless LAN Controller (WLC) Software 8.10.151.0 and 8.10.162.0 allows remote attackers to log in as administrators. The management-interface password validation algorithm accepts crafted credentials when MAC-filter RADIUS compatibility is set to Other, bypassing normal authentication. The non-default configuration is required; successful access grants administrator-level control of the controller.
