# FaceSentry Access Control System 6.4.8 Remote Root Exploit
#
#
# 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: FaceSentry suffers from an authenticated OS command
# injection vulnerability using default credentials. This can
# be exploited to inject and execute arbitrary shell commands
# as the root user via the 'strInIP' POST parameter in pingTest
# PHP script.
