HITACHI ENERGY TRO600

Release Date
November 12, 2024
Alert Code
ICSA-24-317-02
Related topics:
Industrial Control System Vulnerabilities, Industrial Control Systems


View CSAF(link is external)


1. EXECUTIVE SUMMARY

 * CVSS v3 7.2
 * ATTENTION: Exploitable remotely/low attack complexity
 * Vendor: Hitachi Energy
 * Equipment: TRO600 Series
 * Vulnerabilities: Command Injection, Improper Removal of Sensitive Information
   Before Storage or Transfer


2. RISK EVALUATION

Command injection vulnerability in the Edge Computing UI for the TRO600 series
radios that allows for the execution of arbitrary system commands. If exploited,
an attacker with write access to the web UI can execute commands on the device
with root privileges, far more extensively than the write privilege intends.
Profile files from TRO600 series radios are extracted in plain-text and
encrypted file formats. Profile files provide potential attackers valuable
configuration information about the Tropos network. Profiles can only be
exported by authenticated users with write access.


3. TECHNICAL DETAILS


3.1 AFFECTED PRODUCTS

The following products of Hitachi Energy are affected:

 * Hitachi Energy TRO600 series firmware versions: 9.0.1.0 - 9.2.0.0
   (CVE-2024-41156)
 * Hitachi Energy TRO600 series firmware versions: 9.1.0.0 - 9.2.0.0
   (CVE-2024-41153)


3.2 VULNERABILITY OVERVIEW

3.2.1 IMPROPER NEUTRALIZATION OF SPECIAL ELEMENTS USED IN A COMMAND ('COMMAND
INJECTION') CWE-77(LINK IS EXTERNAL)

Command injection vulnerability in the Edge Computing UI for the TRO600 series
radios that allows for the execution of arbitrary system commands. If exploited,
an attacker with write access to the web UI can execute commands on the device
with root privileges, far more extensive than what the write privilege intends.

CVE-2024-41153(link is external) has been assigned to this vulnerability. A CVSS
v3 base score of 7.2 has been assigned; the CVSS vector string is
(CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H(link is external)).

3.2.2 IMPROPER REMOVAL OF SENSITIVE INFORMATION BEFORE STORAGE OR TRANSFER
CWE-212(LINK IS EXTERNAL)

Profile files from TRO600 series radios are extracted in plain-text and
encrypted file formats. Profile files provide potential attackers valuable
configuration information about the Tropos network. Profiles can only be
exported by authenticated users with write access.

CVE-2024-41156(link is external) has been assigned to this vulnerability. A CVSS
v3 base score of 2.7 has been assigned; the CVSS vector string is
(CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:N/A:N(link is external)).


3.3 BACKGROUND

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


3.4 RESEARCHER

Riley Barello-Myers, Idaho National Lab - CyTRICS reported these vulnerabilities
to Hitachi Energy.


4. MITIGATIONS

Hitachi Energy has identified the following specific workarounds and mitigations
users can apply to reduce risk:

 * (CVE-2024-41153) Hitachi Energy TRO600 series firmware versions from 9.1.0.0
   to 9.2.0.0 (Edge computing functionality): Update to version 9.2.0.5
 * (CVE-2024-41156) Hitachi Energy TRO600 series firmware versions from 9.0.1.0
   to 9.2.0.0 (Configuration utility): Update to version 9.2.0.5

Hitachi Energy has provided the additional following security practices and
firewall configurations can help protect a process control network from attacks
that originate from outside the network:

 * Physically protect process control systems from direct access by unauthorized
   personnel.
 * Do not connect directly to the Internet.
 * Separate from other networks by means of a firewall system that has a minimal
   number of ports exposed.
 * Process control systems should not be used for Internet surfing, instant
   messaging, or receiving e-mails.
 * Portable computers and removable storage media should be carefully scanned
   for viruses before they are connected to a control system.

For more details, refer to the "Configuration Guide" document for the respective
TRO600 series router version.

For more information, see Hitachi Energy's security advisory 8DBD000147(link is

CISA recommends users take defensive measures to minimize the risk of
exploitation of these vulnerabilities, such as:

 * Minimize network exposure for all control system devices and/or systems,
   ensuring they are not accessible from the internet.
 * Locate control system networks and remote devices behind firewalls and
   isolating them from business networks.
 * When remote access is required, use more secure methods, such as Virtual
   Private Networks (VPNs). Recognize VPNs may have vulnerabilities, should be
   updated to the most recent version available, and are only as secure as the
   connected devices.

CISA reminds organizations to perform proper impact analysis and risk assessment
prior to deploying defensive measures.

CISA also provides a section for control systems security recommended practices
on the ICS webpage on cisa.gov. Several CISA products detailing cyber defense
best practices are available for reading and download, including Improving
Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.

CISA encourages organizations to implement recommended cybersecurity strategies
for proactive defense of ICS assets.

Additional mitigation guidance and recommended practices are publicly available
on the ICS webpage at cisa.gov in the technical information paper,
ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation
Strategies.

Organizations observing suspected malicious activity should follow established
internal procedures and report findings to CISA for tracking and correlation
against other incidents.

No known public exploitation specifically targeting these vulnerabilities has
been reported to CISA at this time.
