The QR-code upgrade allows you to share an eKey with guests while you're away from your Office and monitor all activity via the web administration tool.

FaceSentry 5AN is a true enterprise grade access control or time-and-attendance appliance. Desc: FaceSentry is vulnerable to multiple cross-site scripting vulnerabilities. This issue is due to the application's failure to properly sanitize user-supplied input thru the 'msg' parameter (GET) in pluginInstall.php script. An attacker may leverage any of the cross-site scripting issues to have arbitrary script code executed in the browser of an unsuspecting user in the context of the affected site. This may facilitate the theft of cookie-based authentication credentials, phishing, as well as other attacks.
