Stored script execution via unvalidated page input
Published Jan 17, 2024 · Updated Oct 21, 2024
Stored XSS in affected Cisco Identity Services Engine 2.7 through 3.3 releases allows remote authenticated users to run browser scripts. Specific management-interface pages store injected code without properly validating user-supplied input and later render it to another user. Exploitation requires high-privilege interface access and victim interaction; successful scripts can act in the interface context or read sensitive browser data.
