CVE-2024-20437Network attack vector

CLI command execution via insufficient CSRF protection

Published Sep 25, 2024 · Updated Sep 25, 2024

Cross-site request forgery in the Cisco IOS XE Software web UI allows remote attackers to execute CLI commands through an authenticated user. The web-based management interface lacks sufficient CSRF protections and treats a crafted link followed by an authenticated user as authorized device actions. Exposure requires a vulnerable release with the HTTP Server and nondefault service internal features enabled; actions run with the targeted user's privileges.
