Stored script execution via DDNS password
Published Jan 17, 2024 · Updated Jun 17, 2025
Stored XSS in Skyworth Digital CM5100 4.1.1.24 and earlier allows remote authenticated users to inject script through the DDNS password field. The web interface accepts and stores crafted password content without neutralizing it before that value is included in a later page. High-privilege access to the web interface is required, and the payload executes only when another user views the stored content.
