CVE-2022-20735Network attack vector

User-privileged actions via forged web requests

Published Apr 15, 2022 · Updated Nov 6, 2024

Cross-site request forgery in Cisco Catalyst SD-WAN Manager allows remote attackers to perform actions as an interface user. The web-based management interface does not sufficiently validate that state-changing requests originated from its own pages. Exploitation requires persuading an authenticated interface user to click a malicious link, enabling configuration changes or account deletion at that user's privilege level.
