# SSA-346262: Denial-of-Service in Industrial Products

Publication Date:        2017-11-23
Last Update:             2022-02-08
Current Version:         3.2
CVSS v3.1 Base Score:    7.5

SUMMARY
=======

Several industrial products are affected by a vulnerability that could
allow remote attackers to conduct a Denial-of-Service (DoS) attack by
sending specially crafted packets to port 161/udp (SNMP).

Siemens has released updates for several affected products, and
recommends that customers update to the new version. Siemens is
preparing further updates and recommends specific countermeasures until
patches are available.

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

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

* Disable SNMP if this is supported by the product (refer to the product
documentation). Disabling SNMP fully mitigates the vulnerability.

* Protect network access to port 161/udp of affected devices.

* Apply cell protection concept and implement Defense-in-Depth:
https://www.siemens.com/cert/operational-guidelines-industrial-security.

* Use VPN for protecting network communication between cells.



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
===================

Development/Evaluation Kits for PROFINET IO are used to develop compact
or modular PROFINET field devices.

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

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,

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-2017-12741

  Specially crafted packets sent to port 161/udp could cause a
  Denial-of-Service condition. The affected devices must be restarted
  manually.

  CVSS v3.1 Base Score: 7.5
  CVSS Vector:          CVSS:3.1/AV:N/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


ACKNOWLEDGMENTS
