Stored XSS in the Skyworth Digital CM5100 4.1.1.24 and earlier allows remote authenticated users to inject script through SMTP Password. The web interface inadequately validates the supplied SMTP Password value before storing it and later rendering it into a management page. High-privilege access is required to plant the payload, and script execution requires another user's interaction with the affected interface.
