Title: FaceSentry Access Control System 6.4.8 Reflected Cross-Site Scripting
Advisory ID: ZSL-2019-5527
Type: Local/Remote
Impact: Cross-Site Scripting
Risk: (3/5)
Release Date: 30.06.2019

Summary

FaceSentry 5AN is a revolutionary smart identity management appliance that offers entry via biometric face identification, contactless smart card, staff ID, or QR-code. 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. Powered by standard PoE (Power over Ethernet), FaceSEntry 5AN can be installed in minutes with only 6 screws. FaceSentry 5AN is a true enterprise grade access control or time-and-attendance appliance.

Description

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.
