Authenticated script execution via unvalidated stored input
Published Jun 28, 2023 · Updated Oct 25, 2024
Stored XSS in the Cisco Secure Web Appliance web interface allows remote authenticated users to execute script through a crafted link. Cisco has not disclosed the affected field; the interface insufficiently validates stored user input and later renders it as script. Exploitation requires high-privilege authentication and another user's interaction; attacks execute code in the interface context or expose sensitive browser data.
