CVE-2020-3261Network attack vector

Configuration changes via missing CSRF protections

Published Apr 15, 2020 · Updated Nov 15, 2024

Cross-site request forgery in Cisco Mobility Express allows remote attackers to change device configuration through its management interface. The web interface lacks sufficient CSRF protections and accepts requests initiated by a malicious link as actions from the user's active session. Exploitation requires a logged-in user to follow the link, and resulting actions run with that user's privileges, including configuration changes.
