# SSA-293562: Denial of Service Vulnerabilities in PROFINET DCP Implementation of
Industrial Products

Publication Date:        2017-05-08
Last Update:             2022-02-08
Current Version:         3.4
CVSS v3.1 Base Score:    6.5

SUMMARY
=======

Several industrial devices are affected by two vulnerabilities that
could allow an attacker to cause a denial of service condition via
PROFINET DCP network packets under certain circumstances. The
precondition for this scenario is a direct layer 2 access to the
affected products. PROFIBUS interfaces are not affected.

Siemens has released updates for several affected products and
recommends to update to the new versions. Siemens recommends specific
countermeasures for products where updates are not, or not yet
available.

WORKAROUNDS AND MITIGATIONS
===========================

Siemens has identified the following specific workarounds and mitigations that
customers can apply to reduce the risk:

* Apply cell protection concept:
https://www.siemens.com/cert/operational-guidelines-industrial-security.

* Use VPN for protecting network communication between cells.

* Apply Defense-in-Depth:
https://www.siemens.com/cert/operational-guidelines-industrial-security.

* For SIMATIC Teleservice Adapters (IE Basic, IE Standard, IE Advanced):
migrate to a successor product within the SCALANCE M-800 family. For
details refer to the notice of discontinuation.



GENERAL SECURITY RECOMMENDATIONS
================================

As a general security measure, Siemens strongly recommends to protect
network access to devices with appropriate mechanisms. In order to
operate the devices in a protected IT environment, Siemens recommends to
configure the environment according to Siemens' operational guidelines
for Industrial Security (Download:
https://www.siemens.com/cert/operational-guidelines-industrial-security),
and to follow the recommendations in the product manuals.

Additional information on Industrial Security by Siemens can be found
at: https://www.siemens.com/industrialsecurity

SCALANCE W-700 products are wireless communication devices based on IEEE
802.11 standards. They are used to connect all to sorts of WLAN devices
(Access Points or Clients, depending on the operating mode) with a
strong focus on industrial components, like Programmable Logic
Controllers (PLCs) or Human Machine Interfaces (HMIs) and others.

SCALANCE X switches are used to connect industrial components like
Programmable Logic Controllers (PLCs) or Human Machine Interfaces
(HMIs).

Siemens SIMATIC S7-300 CPU families, S7-400 CPU families, S7-1200 CPU
families, and S7-1500 CPU families have been designed for discrete and
continuous control in industrial environments such as manufacturing,
food and beverages, and chemical industries worldwide.

SIMATIC CP 343-1 and CP 443-1 are communication processors (CP) designed
to enable Ethernet communication for SIMATIC S7-300/S7-400 CPUs.

SIMATIC ET 200 Interface modules for PROFINET IO are used to connect
field devices (IO Devices) to controllers (IO Controller) via PROFINET.

SIMATIC HMI Panels are used for operator control and monitoring of
machines and plants.

SIMATIC RF600 Readers are used for the contactless identification of
every kind of object, e.g. transport containers, pallets, production
goods, or it can be generally used for recording goods in bulk.

SIMATIC S7-1500 Software Controller is a SIMATIC software controller for
PC-based automation solutions.

SIMATIC TDC is a multiprocessor automation system for drive, control and

and large serial production environments.

SIPLUS extreme products are designed for reliable operation under
extreme conditions and are based on SIMATIC, LOGO!, SITOP, SINAMICS,
SIMOTION, SCALANCE or other devices. SIPLUS devices use the same
firmware as the product they are based on.

SIRIUS 3RW soft starters permit soft starting and soft rampdown of
three-phase asynchronous motors.

SIRIUS ACT is a modular system of pushbuttons and indicator lights for
front plate mounting and rear-mounted electrical modules.

uninterruptible rated currents up to 40A from battery modules.

Softnet PROFINET IO for PC-based Windows systems allows setting up open
control solutions on standard PC hardware.

TeleControl Server Basic allows remote monitoring and control of plants.

The Development Kit DK-16xx PN IO permits an easy integration of CP 1616
and CP 1604 in non-Windows operating system environments.

The IE/AS-i LINK PN IO is a compact network transition between
PROFINET/Industrial Ethernet (PROFINET IO-Device) and AS-Interface.

The S7-200 SMART series is a line of micro-programmable logic
controllers that can control a variety of small automation applications.

The SCALANCE M-800, MUM-800 and S615 as well as the RUGGEDCOM RM1224
industrial routers are used for secure remote access to plants via
mobile networks, e.g. GPRS or UMTS with the integrated security
functions of a firewall for protection against unauthorized access and
VPN to protect data transmission.

The SIMATIC CM 1542-1 communication module is used to connect S7-1500
controllers to PROFINET as IO-Controller.

The SIMATIC CP 1243-1 communication processor connects the S7-1200
controller to Ethernet networks. It provides integrated security
functions such as firewall, Virtual Private Networks (VPN) and support
of other protocols with data encryption.

The SIMATIC CP 1543-1, CP 1543SP-1, CP 1542SP-1 and CP 1542SP-1 IRC
communication processors connects the S7-1500 controller to Ethernet
networks. It provides integrated security functions such as firewall,
Virtual Private Networks (VPN) and support of other protocols with data
encryption.

The SIMATIC CP 1616 and CP 1604 interface cards are used for connecting
Personal Computers and PCI-104 systems to PROFINET IO.

The SINAMICS converter family is used to control a wide variety of
drives, especially in mechanical engineering and plant construction.

The SITOP PSU8600 expandable power supply system is connected to a
3-phase AC line supply to offer regulated DC power.

The stationary optical readers of the SIMATIC MV400 family are used to
reliably capture printed, lasered, drilled, punched and dotpeen codes on
a variety of different surfaces.

VULNERABILITY CLASSIFICATION
============================

The vulnerability classification has been performed by using the CVSS scoring
system in version 3.1 (CVSS v3.1) (https://www.first.org/cvss/). The CVSS
environmental score is specific to the customer's environment and will impact
the overall CVSS score. The environmental score should therefore be
individually defined by the customer to accomplish final scoring.

An additional classification has been performed using the CWE classification, a
community-developed list of common software security weaknesses. This serves as
a common language and as a baseline for weakness identification, mitigation,
and prevention efforts. A detailed list of CWE classes can be found at:
https://cwe.mitre.org/.



* Vulnerability CVE-2017-2680

  Specially crafted PROFINET DCP broadcast packets could cause a denial of
  service condition of affected products on a local Ethernet segment
  (Layer 2). Human interaction is required to recover the systems.
