CVE-2022-20787Network attack vector

User-privileged actions via insufficient CSRF protections

Published Apr 21, 2022 · Updated Nov 6, 2024

CSRF in vulnerable Cisco Unified Communications Manager releases allows remote authenticated users to act with a targeted user's privileges. The web-based management interface applies insufficient CSRF protection, so a crafted link can submit requests through the user's authenticated session. Exploitation requires high-privileged access and persuading an interface user to click the link; resulting actions inherit that user's privileges.
