3.2 Vulnerability Overview
3.2.1 IMPROPER NEUTRALIZATION OF SPECIAL ELEMENTS IN DATA QUERY LOGIC CWE-943
A vulnerability exists in the query validation of the MicroSCADA Pro/X SYS600 product. If exploited this could allow an authenticated attacker to inject code towards persistent data. Note that to successfully exploit this vulnerability an attacker must have a valid credential.
CVE-2024-4872 has been assigned to this vulnerability. A CVSS v3 base score of 9.9 has been assigned; the CVSS vector string is (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H).
3.2.2 IMPROPER LIMITATION OF A PATHNAME TO A RESTRICTED DIRECTORY (‘PATH TRAVERSAL’) CWE-22
The MicroSCADA Pro/X SYS600 product allows an authenticated user input to control or influence paths or file names that are used in filesystem operations. If exploited the vulnerability allows the attacker to access or modify system files or other files that are critical to the application.
CVE-2024-3980 has been assigned to this vulnerability. A CVSS v3 base score of 8.8 has been assigned; the CVSS vector string is (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H).
3.2.3 AUTHENTICATION BYPASS BY CAPTURE-REPLAY CWE-294
An attacker with local access to a machine where MicroSCADA X SYS600 is installed could enable session logging and try to exploit a session hijacking of an already established session. By default, the session logging level is not enabled and only users with administrator rights can enable it.
CVE-2024-3982 has been assigned to this vulnerability. A CVSS v3 base score of 8.2 has been assigned; the CVSS vector string is (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H).
3.2.4 MISSING AUTHENTICATION FOR CRITICAL FUNCTION CWE-306
The product exposes a service that is intended for local only to all network interfaces without any authentication.
CVE-2024-7940 has been assigned to this vulnerability. A CVSS v3 base score of 8.3 has been assigned; the CVSS vector string is (CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H).
3.2.5 URL REDIRECTION TO UNTRUSTED SITE (‘OPEN REDIRECT’) CWE-601
A HTTP parameter may contain a URL value and could cause the web application to redirect the request to the specified URL. By modifying the URL value to a malicious site, an attacker may successfully launch a phishing scam and steal user credentials.
CVE-2024-7941 has been assigned to this vulnerability. A CVSS v3 base score of 4.3 has been assigned; the CVSS vector string is (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N).

Hitachi Energy recommends the following security practices and firewall configurations to help protect process control networks from attacks that originate from outside the network:
- Ensure 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.
- 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.
For detailed mitigation strategies, users can approach their Hitachi Energy organization contact.
Hitachi Electric highly recommends deploying the product following the “MicroSCADA cybersecurity deployment guideline” document. Users should maintain their systems with products running on supported versions and follow maintenance releases.
