2. RISK EVALUATION Successful exploitation of these vulnerabilities could allow an attacker to retrieve credentials without authentication.
3. TECHNICAL DETAILS 3.1 AFFECTED PRODUCTS The following versions of Dingtian DT-R002, a relay board, are affected: DT-R002: All versions 3.2 VULNERABILITY OVERVIEW 3.2.1 INSUFFICIENTLY PROTECTED CREDENTIALS CWE-522 All versions of Dingtian DT-R002 are vulnerable to an Insufficiently Protected Credentials vulnerability that could allow an attacker to retrieve the current user’s username without authentication. CVE-2025-10879 has been assigned to this vulnerability. A CVSS v3.1 base score of 7.5 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N. A CVSS v4 score has also been calculated for CVE-2025-10879. A base score of 8.7 has been calculated; the CVSS vector string is (AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N). 3.2.2 INSUFFICIENTLY PROTECTED CREDENTIALS CWE-522 All versions of Dingtian DT-R002 are vulnerable to an Insufficiently Protected Credentials vulnerability that could allow an attacker to extract the proprietary “Dingtian Binary” protocol password by sending an unauthenticated GET request CVE-2025-10880 has been assigned to this vulnerability. A CVSS v3.1 base score of 7.5 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N. A CVSS v4 score has also been calculated for CVE-2025-10880. A base score of 8.7 has been calculated; the CVSS vector string is (AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N). 3.3 BACKGROUND CRITICAL INFRASTRUCTURE SECTORS: Critical Manufacturing COUNTRIES/AREAS DEPLOYED: Worldwide COMPANY HEADQUARTERS LOCATION: China 3.4 RESEARCHER Nicolas Cano and Reid Wightman of Dragos reported these vulnerabilities to CISA.
4. MITIGATIONS Dingtian has not responded to requests to work with CISA to mitigate these vulnerabilities. Users of affected versions of Dingtian DT-R002 are invited to contact Dingtian customer support for additional information. The researchers recommend the following to help reduce risk: Restrict access to HTTP (TCP/80), and the Dingtian Protocol on (UDP/60000) and (UDP/60001). 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), 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 these vulnerabilities has been reported to CISA at this time.
