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:	V3.4
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.

PRODUCT DESCRIPTION

IE/PB-Link devices enable existing PROFIBUS devices to be integrated into a PROFINET application.

PN/PN coupler is used for connecting two PROFINET networks.

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 technology tasks. The system is used particularly for large plants.

SIMATIC Teleservice adapters allow for remote maintenance of automation systems via phone or internet. The adapters are superseded by the SCALANCE M product family.

SIMATIC WinAC RTX (F) 2010 is a SIMATIC software controller for PC-based automation solutions.

SIMOCODE is the flexible and modular motor management system for low-voltage motors.

SIMOTION is a scalable high performance hardware and software system for motion control.

SINUMERIK CNC offers automation solutions for the shop floor, job shops 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.

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. PROFIBUS interfaces are not affected.

CVSS v3.1 Base Score	6.5
CVSS Vector	CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:P/RL:O/RC:C
CWE:	CWE-400: Uncontrolled Resource Consumption

Vulnerability CVE-2017-2681

Specially crafted PROFINET DCP packets sent on a local Ethernet segment (Layer 2) to an affected product could cause a denial of service condition of that product. Human interaction is required to recover the system. PROFIBUS interfaces are not affected. This vulnerability affects only SIMATIC HMI Multi Panels and HMI Mobile Panels, and S7-300/S7-400 devices.

CVSS v3.1 Base Score	6.5
CVSS Vector	CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:P/RL:O/RC:C
CWE:	CWE-400: Uncontrolled Resource Consumption
