CVE-2020-3532Network attack vector

Script execution via unvalidated management-interface input

Published Nov 18, 2024 · Updated Nov 18, 2024

Cross-site scripting in Cisco Unified Communications products allows remote attackers to execute script through a crafted link. The web-based management interface accepts user-supplied input without proper validation and reflects it into an executable browser context. A management-interface user must click the link; exploitation runs code in that interface's context or exposes sensitive browser data.
