# Summary: Apros Evoluation / Furukawa / ConsciusMap is the Tecnored
# provisioning system for FTTH networks. Complete administration of
# your entire external FTTH network plant, including from the ONUs
# installed in each end customer, to the wiring and junction boxes.
# Unify all the management of your FTTH network on a single platform.
# Unify all your data, whether from customers, your network, or the
# external plant in one place. APROS FTTH allows you to manage your
# entire FTTH network in a simple and globalized way with just one
# click, without being a network expert. Includes services such as:
# bandwidth limitation, Turbo Internet for time plans, BURST Internet,
# QinQ for companies, and many more. General consumption graphics and
# per customer in real time. Captive Portal for cutting or suspension
# of the service.
#
# Desc: The FTTH provisioning solution suffers from an unauthenticated
# remote code execution vulnerability due to an unsafe deserialization
# of Java objects (ViewState) triggered via the 'javax.faces.ViewState'
# HTTP POST parameter. The deserialization can cause the vulnerable JSF
# web application to execute arbitrary Java functions, malicious Java
# bytecode, and system shell commands with root privileges.
