Cross-site scripting vulnerabilities are triggered when a specially crafted value is assigned to different variables in scripts, which allows one to manage device through Web-interface. This can be exploited to inject malicious code and execute arbitrary HTML or script code in the admin browser session in the context of the device's web management interface.
