CVE-2023-20257Network attack vector

Stored XSS via unvalidated management-interface input

Published Jan 17, 2024 · Updated Jun 17, 2025

Stored XSS in Cisco EPNM and Prime Infrastructure allows remote authenticated users to execute script in other users' sessions. The web management interface stores script or HTML content from requests without properly validating it, then serves that content within the application interface. The attacker needs privileges to access the web interface, and another user must view the stored content; execution is confined to the victim's browser context.
