The SpeedTouch 500 series are prone to a cross-site scripting vulnerability. This issue is due to a failure in the devices to properly sanitize user-supplied input. 
 
An attacker may leverage this issue to have arbitrary script code executed in the browser of an unsuspecting user in the context of the affected site. This may facilitate the compromise of the device.
