RISKY CRYPTOGRAPHIC ALGORITHM CWE-327 The affected products support insecure cryptographic algorithms. An attacker could leverage these legacy algorithms to achieve a man-in-the-middle attack or impersonate communicating parties. CVE-2023-52236 has been assigned to this vulnerability. A CVSS v3.1 base score of 7.0 has been calculated; the CVSS vector string is (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:L/A:L). A CVSS v4 score has also been calculated for CVE-2023-52236. A base score of 6.1 has been calculated; the CVSS vector string is (CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:P/VC:H/VI:L/VA:L/SC:N/SI:N/SA:N). 3.2.2 IMPROPER HANDLING OF EXCEPTIONAL CONDITIONS CWE-755 Affected devices do not properly handle malformed TLS handshake messages. This could allow an attacker with network access to the webserver to cause a denial of service resulting in the web server and the device to crash. CVE-2025-41222 has been assigned to this vulnerability. A CVSS v3.1 base score of 5.3 has been calculated; the CVSS vector string is (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L). A CVSS v4 score has also been calculated for CVE-2025-41222. A base score of 6.9 has been calculated; the CVSS vector string is (CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N). 3.2.3 USE OF A BROKEN OR RISKY CRYPTOGRAPHIC ALGORITHM CWE-327 The affected devices support the TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256 cipher suite, which uses CBC (Cipher Block Chaining) mode that is known to be vulnerable to timing attacks. This could allow an attacker to compromise the integrity and confidentiality of encrypted communications. CVE-2025-41223 has been assigned to this vulnerability. A CVSS v3.1 base score of 4.8 has been calculated; the CVSS vector string is (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N). A CVSS v4 score has also been calculated for CVE-2025-41223. A base score of 6.3 has been calculated; the CVSS vector string is (CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N). 3.2.4 PROTECTION MECHANISM FAILURE CWE-693 The affected products do not properly enforce interface access restrictions when changing from management to non-management interface configurations until a system reboot occurs, despite configuration being saved. This could allow an attacker with network access and credentials to gain access to the device through non-management and maintain SSH access to the device until reboot. CVE-2025-41224 has been assigned to this vulnerability. A CVSS v3.1 base score of 8.8 has been calculated; the CVSS vector string is (CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). A CVSS v4 score has also been calculated for CVE-2025-41224. A base score of 7.7 has been calculated; the CVSS vector string is (CVSS:4.0/AV:A/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N). 3.3 BACKGROUND CRITICAL INFRASTRUCTURE SECTORS: Critical Manufacturing COUNTRIES/AREAS DEPLOYED: Worldwide COMPANY HEADQUARTERS LOCATION: Germany 3.4 RESEARCHER Thomas Riedmaier from Siemens Energy reported these vulnerabilities to Siemens.

As a general security measure, Siemens recommends protecting network access to devices with appropriate mechanisms. To operate the devices in a protected IT environment, Siemens recommends configuring the environment according to Siemens’ operational guidelines for industrial security and following recommendations in the product manuals. Additional information on industrial security by Siemens can be found on the Siemens industrial security webpage. For more information see the associated Siemens security advisory SSA-083019 in HTML and CSAF. 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.
