Vendor: iWT Ltd.  
Product web page: http://www.iwt.com.hk  
Affected version: Firmware 6.4.8 build 264 (Algorithm A16)  
Firmware 5.7.2 build 568 (Algorithm A14)  
Firmware 5.7.0 build 539 (Algorithm A14)  
  
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.  
  
Desc: The application interface allows users to perform certain  
actions via HTTP requests without performing any validity checks  
to verify the requests. This can be exploited to perform certain  
actions with administrative privileges if a logged-in user visits  
a malicious web site.
