Hitachi Energy reports multiple open-source software related vulnerabilities in the following MSM product versions: 

  • MSM version 2.2 and earlier.

3.2 VULNERABILITY OVERVIEW

3.2.1    RELIANCE ON UNCONTROLLED COMPONENT CWE-1357

Hitachi Energy is aware of public reports of multiple vulnerabilities in open-source software components (JQuery, GoAhead Embedded Webserver, and Curl) used in MSM products. Versions are available to remediate the identified vulnerabilities.

CVE-2015-6584, CVE-2016-7103, CVE-2011-4273, CVE-2018-16842, CVE-2016-9586, CVE-2016-8617, CVE-2016-8618, CVE-2016-8619, CVE-2016-8621, CVE-2016-7167, CVE-2014-3707, CVE-2013-2174, and CVE-2014-0138, have been assigned to these vulnerabilities in open-source components used by MSM. A CVSS v3 base score of 9.8 has been calculated for the worst case; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). 

3.3 BACKGROUND

  • CRITICAL INFRASTRUCTURE SECTORS: Energy
  • COUNTRIES/AREAS DEPLOYED: Worldwide
  • COMPANY HEADQUARTERS LOCATION: Switzerland

3.4 RESEARCHER

Hitachi Energy reported to CISA that MSM products were affected by these previously discovered vulnerabilities in various open-source software components.

4. MITIGATIONS

Hitachi Energy recommends the following security practices and firewall configurations to help protect process control networks from outside attacks:

  • Physically protect process control systems from unauthorized direct access.
  • Separate process control systems from other networks using a firewall system with only the necessary ports open.
  • Process control systems should not be used for common internet activities.
  • Portable computers and removable storage media should be carefully scanned for malicious software before connecting to a control system.

Hitachi Energy also recommends following the hardening guidelines published by The Center for Internet Security (CIS) to protect hosts connected with MSM. This measure will prevent the lateral movement of the attack vector into MSM via such connected devices. Examples for Windows computers include:
