CISA advisories
View CSAF Summary Hitachi Energy is aware of OS command injection and Dirty Frag vulnerabilities that affect CoreTec product versions listed in this document. Successful exploitation of these vulnerabilities could result in impact on confidentiality, integrity and availability of the product. Please refer to the Recommended Immediate Actions for information about the mitigation/remediation. The following versions of Hitachi Energy CoreTec Product are affected: CoreTec5 vers:CoreTec5/<=3.4.0, 5.0.0 (CVE-2026-13162, CVE-2026-43284) CoreTec4 vers:CoreTec4/<=3.4.0 (CVE-2026-13162) CVSS Vendor Equipment v3 8.8 Hitachi Energy CoreTec5 2 Vulnerabilities Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection'), Write-what-where Condition Background Critical Infrastructure Sectors: Energy Countries/Areas Deployed: Worldwide Company Headquarters Location: Switzerland Vulnerabilities Expand All + CVE-2026-13162 An OS command vulnerability exists in CoreTec product that allows authenticated users with certain roles to execute arbitrary system commands with full control over the device. The vulnerability exists in the configuration daemon's time synchronization handler, which is responsible for setting the system timezone. When processing timezone configuration updates, the daemon constructs a shell command by concatenating user-supplied input without any sanitization or validation.

The flaw exists in how the kernel handles memory pages when processing ESP encrypted network packets. An attacker can craft a packet that causes the kernel to decrypt data directly into memory pages it does not own, including cached copies of privileged operating system binaries. When one of those binaries is executed, the attacker's injected code runs with root privileges. In CoreTec5, the vulnerable ESP component is compiled in kernel as a built-in and is present at boot time allowing a local user to exploit it.

General Mitigation Factors Recommended security practices and firewall configurations can help protect a process control network from attacks that originate from outside the network. Such practices include that process control systems are physically protected from direct access by unauthorized personnel, have no direct connections to the Internet, and are separated from other networks by means of a firewall system that has a minimal number of ports exposed, and others that have to be evaluated case by case. 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. Proper password policies and processes should be followed. Additional information on Industrial Control Systems Cybersecurity Best Practices can be found in the Hitachi Energy “Industrial Control Systems Cybersecurity Best Practices” Cybersecurity Notification. [1] SSVC SSVCv2/E:N/A:N/2026-10-26T15:17:24Z/ Recommended Practices CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities. 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), recognizing VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is 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/ics. 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/ics 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.
