Hitachi Energy MACH SCM
Release Date
April 25, 2024
1. EXECUTIVE SUMMARY
o CVSS v4 8.9
o ATTENTION : Exploitable remotely
o Vendor : Hitachi Energy
o Equipment : MACH SCM
o Vulnerabilities : Improper Control of Generation of Code, Improper
Neutralization of Directives in Dynamically Evaluated Code
2. RISK EVALUATION
Successful exploitation of these vulnerabilities could result in an execution
of arbitrary code.
3. TECHNICAL DETAILS
3.1 AFFECTED PRODUCTS
The following versions of MACH SCM, are affected:
o MACH SCM: Versions 4.0 to 4.5.x
o MACH SCM: Versions 4.6 to 4.38
3.2 Vulnerability Overview
3.2.1 IMPROPER CONTROL OF GENERATION OF CODE CWE-94
SCM Software is a client and server application. An Authenticated System
manager client can execute LINQ query in the SCM server, for customized
filtering. An Authenticated malicious client can send a specially crafted code
to skip the validation and execute arbitrary code (RCE) on the SCM Server
remotely. Malicious clients can execute any command by using this RCE
vulnerability.
CVE-2024-0400 has been assigned to this vulnerability. A CVSS v3.1 base score
of 7.5 has been calculated; the CVSS vector string is ( AV:N/AC:H/PR:L/UI:N/S:U
/C:H/I:H/A:H ).
A CVSS v4 score has also been calculated for CVE-2024-0400 . A base score of
8.9 has been calculated; the CVSS vector string is ( CVSS:4.0/AV:N/AC:H/AT:N/
PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:L ).
3.2.2 IMPROPER NEUTRILIZATION OF DIRECTIVES IN DYNAMICALLY EVALUATED CODE
CWE-95
Authenticated List control client can execute the LINQ query in SCM Server to
present event as list for operator. An authenticated malicious client can send
special LINQ query to execute arbitrary code remotely (RCE) on the SCM Server
that an attacker otherwise does not have authorization to do.
CVE-2024-2097 has been assigned to this vulnerability. A CVSS v3.1 base score
of 7.5 has been calculated; the CVSS vector string is ( AV:N/AC:H/PR:L/UI:N/S:U
/C:H/I:H/A:H ).
A CVSS v4 score has also been calculated for CVE-2024-2097 . A base score of
8.8 has been calculated; the CVSS vector string is ( CVSS:4.0/AV:N/AC:H/AT:N/
PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:H/SA:L ).
3.3 BACKGROUND
o CRITICAL INFRASTRUCTURE SECTORS: Energy
o COUNTRIES/AREAS DEPLOYED: Worldwide
o COMPANY HEADQUARTERS LOCATION: Switzerland
3.4 RESEARCHER
Hitachi Energy reported these vulnerabilities to CISA.
4. MITIGATIONS
Hitachi Energy has released the following mitigation for CVE-2024-2097:
o MACH SCM: Versions 4.6 to 4.38: Upgrade to MACH SCM Version 4.38.1
Until the updates are made available, Hitachi Energy recommends the following
general mitigation factors/workarounds for the products with MACH SCM Versions
4.0 to 4.5.x to address the vulnerability CVE-2024-0400:
Recommended security practices and firewall configurations can help protect a
process control network from attacks originating from outside the network
including:
o Physically protect process control systems from direct access by
unauthorized personnel.
o Do not allow process control systems direct connections to the Internet.
o Separate process control systems from other networks by means of a firewall
system that has a minimal number of ports exposed.
o Process control systems should not be used for Internet surfing, instant
messaging, or receiving emails.
o Portable computers and removable storage media should be carefully scanned
for viruses before they are connected to a control system.
