CVE-2023-51724Network attack vector

Stored script execution via unvalidated URL parameter

Published Jan 17, 2024 · Updated Jun 17, 2025

Stored XSS in the Skyworth Digital CM5100 4.1.1.24 web interface allows remote authenticated users to execute script via the URL parameter. The web interface accepts the URL value without sufficient validation and later renders the stored value in a browser context. Administrative access and a user who views the affected page are required; exploitation executes attacker-controlled script in that user's browser.
