Category: CISA Alerts

 ​CISA and the Federal Bureau of Investigation (FBI) have released a Secure by Design Alert, Eliminating Buffer Overflow Vulnerabilities, as part of their cooperative Secure by Design Alert series—an ongoing series aimed at advancing industry-wide best practices to eliminate entire classes of vulnerabilities during the design and development phases of the product lifecycle. “Eliminating Buffer Overflow Vulnerabilities” describes proven techniques to prevent or mitigate buffer overflow vulnerabilities through secure by design principles and best practices.
Buffer overflow vulnerabilities are a prevalent type of defect in memory-safe software design that can lead to system compromise. These vulnerabilities can lead to data corruption, sensitive data exposure, program crashes, and unauthorized code execution. Threat actors frequently exploit these vulnerabilities to gain initial access to an organization’s network and then move laterally to the wider network.
CISA and FBI urge manufacturers review the Alert and, where feasible, eliminate this class of defect by developing new software using memory-safe languages, using secure by design methods, and implementing the best practices supplied in this Alert. CISA and FBI also urge software customers demand secure products from manufacturers that include these preventions. Visit CISA’s Secure by Design Pledge page to learn about our voluntary pledge, which focuses on enterprise software products and services—including on-premises software, cloud services, and software as a service (SaaS).

3.4 RESEARCHER
Trimble reported this vulnerability to CISA.
4. MITIGATIONS
Cityworks has released the following update guidance for users:

Trimble will be releasing updated versions to both 15.x (15.8.9 available January 28, 2025) and Cityworks 23.x software releases (23.10 available January 29, 2025). Information on the updated versions will be available through the normal channels via the Cityworks Support Portal(Login required). On-premise customers should install the updated version immediately. These updates will be automatically applied to all Cityworks Online (CWOL) deployments.
Trimble has observed that some on-premise deployments may have overprivileged Internet Information Services (IIS) identity permissions. For avoidance of doubt, and in accordance with Trimble’s technical documentation, IIS should not be run with local or domain level administrative privileges on any site. Please refer to the direction in the latest release notes in the Cityworks Support Portal(Login required) for more information on how to update IIS identity permissions. Trimble’s CWOL customers have their IIS identity permissions set appropriately and do not need to take this action.
Trimble has observed that some deployments have inappropriate attachment directory configurations. Trimble recommends that attachment directory root configuration should be limited to folders/subfolders which only contain attachments. Please refer to the direction in the latest release notes in the Cityworks Support Portal(Login required) for more information on how to ensure proper configuration of the attachment directory.

For more information, see Trimble’s notification.
Cityworks software is incapable of controlling industrial processes, and is not directly part of an ICS.
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.

Schneider Electric strongly recommends the following industry cybersecurity best practices:

Locate control and safety system networks and remote devices behind firewalls and isolate them from the business network.
Install physical controls so no unauthorized personnel can access your industrial control and safety systems, components, peripheral equipment, and networks.
Place all controllers in locked cabinets and never leave them in the “Program” mode.
Never connect programming software to any network other than the network intended for that device.
Scan all methods of mobile data exchange with the isolated network such as CDs, USB drives, etc. before use in the terminals or any node connected to these networks.
Never allow mobile devices that have connected to any other network besides the intended network to connect to the safety or control networks without proper sanitation.
Minimize network exposure for all control system devices and systems and ensure that they are not accessible from the Internet.
When remote access is required, use secure methods, such as virtual private networks (VPNs). Recognize that VPNs may have vulnerabilities and should be updated to the most current version available. Also, understand that VPNs are only as secure as the connected devices.

1. EXECUTIVE SUMMARY

• CVSS v4 5.7
• ATTENTION: Low attack complexity
• Vendor: MicroDicom
• Equipment: DICOM Viewer
• Vulnerability: Improper Certificate Validation

2. RISK EVALUATION

Successful exploitation of this vulnerability could allow an attacker to alter network traffic and perform a machine-in-the-middle (MITM) attack.

3. TECHNICAL DETAILS

3.1 AFFECTED PRODUCTS

The following MicroDicom DICOM Viewer are affected:

• MicroDicom DICOM Viewer: Version 2024.03

3.2 VULNERABILITY OVERVIEW

3.2.1 IMPROPER CERTIFICATE VALIDATION CWE-295

MicroDicom DICOM Viewer fails to adequately verify the update server’s certificate, which could make it possible for attackers in a privileged network position to alter network traffic and carry out a machine-in-the-middle (MITM) attack. This allows the attackers to modify the server’s response and deliver a malicious update to the user.

CVE-2025-1002 has been assigned to this vulnerability. A CVSS v3.1 base score of 5.7 has been calculated; the CVSS vector string is (AV:A/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N).

A CVSS v4 score has also been calculated for CVE-2025-1002. A base score of 5.7 has been calculated; the CVSS vector string is (AV:A/AC:L/AT:P/PR:N/UI:A/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N).

3.3 BACKGROUND

• CRITICAL INFRASTRUCTURE SECTORS: Healthcare and Public Health
• COUNTRIES/AREAS DEPLOYED: Worldwide
• COMPANY HEADQUARTERS LOCATION: Bulgaria

3.4 RESEARCHER

Sharon Brizinov of Claroty Team82 reported this vulnerability to CISA.

4. MITIGATIONS

MicroDicom recommends users upgrade to DICOM Viewer version 2025.1.

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

No known public exploitation specifically targeting this vulnerability has been reported to CISA at this time. This vulnerability is not exploitable remotely.
