Stored XSS via insufficient input validation
Published Jun 28, 2023 · Updated Aug 2, 2024
Stored XSS in Cisco Small Business 200, 300, and 500 Series switch web interfaces allows remote authenticated users to execute browser script. The interface accepts malicious HTML or script content in fields intended for HTML markup and later renders that stored input when another interface user views the affected page. Exploitation requires valid management credentials and user interaction, and it exposes browser-based information or runs script in the interface user's context.
