CVE-2023-20011Network attack vector

Victim-privilege actions via missing CSRF protections

Published Feb 23, 2023 · Updated Oct 28, 2024

Cross-site request forgery in Cisco APIC's web interface allows remote attackers to act with a logged-in user's privileges. The interface lacks sufficient CSRF protections and accepts attacker-induced browser requests as intentional user actions. A user must follow a malicious link while authenticated; an administrative session permits configuration changes and creation of privileged accounts.
