# EyeLock nano NXT 3.5 Remote Root Exploit
#
#
# Vendor: EyeLock, LLC
# Product web page: http://www.eyelock.com
# Affected version: NXT Firmware: 3.05.1193 (ICM: 3.5.1)
# NXT Firmware: 3.04.1108 (ICM: 3.4.13)
# NXT Firmware: 3.03.944(ICM: 3.3.2)
# NXT Firmware: 3.01.646(ICM: 3.1.13)
#
# Platform: Hardware (Biometric Iris Reader (master))
#
# EyeLock is an advanced iris authentication and recognition solutions company
# focused on developing next-generation systems for global access control and identity
# management.
#
# Summary: nano NXT® - the next generation of EyeLock’s revolutionary access
# control solutions. nano NXT renders all other access control peripherals
# obsolete by revolutionizing how identities are protected, authenticated,
# and managed. With a sleek low profile and powerful capabilities, the nano
# NXT redefines the future of access control. An optional SDK is available
# to customers who want to customize their security solutions to integrate
# seamlessly with existing applications. The nano NXT authenticates up to 20
# people per minute, in-motion and at-a-distance with unparalleled accuracy.
# nano NXT can be used in a variety of environments including commercial/enterprise,
# corrections, data centers, education, financial services, government, healthcare
# facilities and hospitality.
#
# Nano NXT is the most advanced compact iris-based identity authentication device
# in Eyelock's comprehensive suite of end-to-end identity authentication solutions.
# Nano NXT is a miniaturized iris-based recognition system capable of providing
# real-time identification, both in-motion and at a distance. The Nano NXT is an
# ideal replacement for card-based systems, and seamlessly controls access to turnstiles,
# secured entrances, server rooms and any other physical space. Similarly the device
# is powerful and compact enough to secure high-value transactions, critical databases,
# network workstations or any other information system.
#
# Desc: EyeLock's nano NXT firmware latest version 3.5 (released 25.07.2016) suffers
# from multiple unauthenticated command injection vulnerabilities. The issue lies
# within the 'rpc.php' script located in the '/scripts' directory and can be triggered
# when user supplied input is not correctly sanitized while updating the local time for
# the device and/or get info from remote time server. The vulnerable script has two REQUEST
# parameters 'timeserver' and 'localtime' that are called within a shell_exec() function
# for setting the local time and the hardware clock of the device. An attacker can exploit
# these conditions gaining full system (root) access and execute OS commands on the affected
# device by injecting special characters to the affected parameters and further bypass
# the access control in place.
#
# Hint: Plenty other RCE bugs are present in the rpc.php and others (like: uploadCertificate.php,
# upgrade.php, WebConfig.php, firmwareupdate.php, interfaceeditor.php, etc.)
