Authenticated script execution via unvalidated crafted links
Published Jan 26, 2024 · Updated Jun 3, 2025
Cross-site scripting in Cisco Unity Connection 14 and earlier allows remote authenticated users to execute script via a crafted link. The web-based management interface fails to validate user-supplied input carried by the link before processing it in the interface. Exploitation requires high privileges and a user to click the link; resulting code runs in the interface context and can access browser data.
