CVE-2022-20963Network attack vector

Authenticated script execution via stored interface input

Published Nov 3, 2022 · Updated Oct 25, 2024

Stored XSS in Cisco Identity Services Engine allows remote authenticated users to execute script in another interface user's browser. Specific management pages store malicious code because the interface does not sufficiently validate user-supplied input; Cisco does not identify those pages. Exploitation requires valid management credentials and a separate interface user to view the injected page, exposing browser-based information or actions in that user's session.
