A CVSS v4 score has also been calculated for CVE-2025-24494. A base score of 8.6 has been calculated; the CVSS vector string is (CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N).

3.2.2 Improper Restriction of XML External Entity Reference CWE-611

External XML entity injection allows arbitrary download of files. The score without least privilege principle violation is as calculated below. In combination with other issues it may facilitate further compromise of the device. Remediation in Version 6.8.0, release date: 01-Mar-25.

CVE-2025-24521 has been assigned to this vulnerability. A CVSS v3.1 base score of 4.9 has been calculated; the CVSS vector string is (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N).

A CVSS v4 score has also been calculated for CVE-2025-24521 . A base score of 6.9 has been calculated; the CVSS vector string is (CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N).

3.2.3 Improper Limitation of a Pathname to a Restricted Directory CWE-22

Path traversal may lead to arbitrary file download. The score without least privilege principle violation is as calculated below. In combination with other issues it may facilitate further compromise of the device. Remediation in Version 6.8.0, release date: 01-Mar-25.

CVE-2025-21095 has been assigned to this vulnerability. A CVSS v3.1 base score of 4.9 has been calculated; the CVSS vector string is (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N).

A CVSS v4 score has also been calculated for CVE-2025-21095. A base score of 6.9 has been calculated; the CVSS vector string is (CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N).

3.2.4 Improper Limitation of a Pathname to a Restricted Directory CWE-22

Path traversal may lead to arbitrary file deletion. The score without least privilege principle violation is as calculated below. In combination with other issues it may facilitate further compromise of the device. Remediation in Version 6.8.0, release date: 01-Mar-25.

CVE-2025-23416 has been assigned to this vulnerability. A CVSS v3.1 base score of 4.9 has been calculated; the CVSS vector string is (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:N).

A CVSS v4 score has also been calculated for CVE-2025-23416. A base score of 6.9 has been calculated; the CVSS vector string is (CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N).

CISA recommends users take defensive measures to minimize the risk of exploitation of this 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), 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.

CISA also recommends users take the following measures to protect themselves from social engineering attacks:

• Do not click web links or open attachments in unsolicited email messages.
• Refer to Recognizing and Avoiding Email Scams for more information on avoiding email scams.
• Refer to Avoiding Social Engineering and Phishing Attacks for more information on social engineering attacks.
