1. EXECUTIVE SUMMARY

  • CVSS v3 6.5
  • ATTENTION: Exploitable from an adjacent network/low skill level to exploit.
  • Vendor: Siemens
  • Equipment: Devices using the PROFINET Discovery and Configuration Protocol (DCP)
  • Vulnerabilities: Improper Input Validation

2. UPDATE INFORMATION

This updated advisory is a follow-up to the updated advisory titled ICSA-17-129-02 Siemens devices using the PROFINET Discovery and Configuration Protocol (Update O) that was published February 5, 2019, on the ICS webpage on us-cert.gov.

3. RISK EVALUATION

Successful exploitation of these vulnerabilities could cause the targeted device to enter a denial-of-service condition, which may require human interaction to recover the system.

4.2 VULNERABILITY OVERVIEW

4.2.1 IMPROPER INPUT VALIDATION CWE-20

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.

CVE-2017-2680 has been assigned to this vulnerability. A CVSS v3 base score of 6.5 has been calculated; the CVSS vector string is (AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H).

4.2.2 IMPROPER INPUT VALIDATION CWE-20

Specially crafted PROFINET DCP packets sent on a local Ethernet segment (Layer 2) to an affected product could cause a denial-of-service condition in 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.

CVE-2017-2681 has been assigned to this vulnerability. A CVSS v3 base score of 6.5 has been calculated; the CVSS vector string is (AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H).

4.3 BACKGROUND

  • Critical Infrastructure Sectors: Chemical, Critical Manufacturing, Energy, Food and Agriculture, Water and Wastewater Systems
  • Countries/Areas Deployed: Worldwide
  • Company Headquarters Location: Germany

4.4 RESEARCHER

Duan JinTong, Ma ShaoShuai, and Cheng Lei from NSFOCUS Security Team reported these vulnerabilities directly to Siemens.

5. MITIGATIONS

The attacker must have network access to the local Ethernet segment (Layer 2).

Siemens strongly recommends verifying the affected products are protected as described in the PROFINET Security Guidelines and Siemens Operational Guidelines to run the devices in a protected IT environment.

Siemens provides firmware updates fixing the vulnerabilities for the following affected products and recommends users update to the new fixed version:
