Stored XSS in Skyworth Digital CM5100 4.1.1.24 and earlier allows remote authenticated users to execute script in a viewer's browser. The Remote endpoint settings page stores crafted Identity parameter input without sufficient validation before including it in generated web content. Exploitation requires high-privileged web-interface access and a subsequent user to view the stored setting; the script then runs in that user's browser.
