CVE-2023-20058Network attack vector

Reflected XSS via unvalidated web input

Published Jan 19, 2023 · Updated Oct 25, 2024

Reflected XSS in Cisco Unified Intelligence Center allows remote attackers to execute script code through crafted links. The web-based management interface fails to validate user-supplied input before reflecting it into a rendered page. Exploitation requires an unauthenticated attacker to persuade an interface user to open a crafted link, enabling script execution in that user's browser context and access to browser-based information.
