1. EXECUTIVE SUMMARY CVSS v4 8.7 ATTENTION: Exploitable remotely/Low attack complexity Vendor: Advantech Equipment: DeviceOn/iEdge Vulnerabilities: Improper Neutralization of Input During Web Page Generation (‘Cross-site Scripting’), Improper Limitation of a Pathname to a Restricted Directory (‘Path Traversal’)
2. RISK EVALUATION Successful exploitation of these vulnerabilities could result in a denial-of-service condition, remote code execution, or an attacker reading arbitrary files.
3. TECHNICAL DETAILS 3.1 AFFECTED PRODUCTS The following version of DeviceOn/iEdge, an IoT management platform, is affected: DeviceOn/iEdge: Version 2.0.2 and prior 3.2 VULNERABILITY OVERVIEW 3.2.1 IMPROPER NEUTRALIZATION OF INPUT DURING WEB PAGE GENERATION (‘CROSS-SITE SCRIPTING’) CWE-79 Insufficient input sanitization in the dashboard label or path can allow an attacker to trigger a device error causing information disclosure or data manipulation. CVE-2025-64302 has been assigned to this vulnerability. A CVSS v3 base score of 6.4 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N). A CVSS v4 score has also been calculated for CVE-2025-64302. A base score of 5.3 has been calculated; the CVSS vector string is (AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:L). 3.2.2 IMPROPER LIMITATION OF A PATHNAME TO A RESTRICTED DIRECTORY (‘PATH TRAVERSAL’) CWE-22 Due to insufficient sanitization, an attacker can upload a specially crafted configuration file to traverse directories and achieve remote code execution with system-level permissions. CVE-2025-62630 has been assigned to this vulnerability. A CVSS v3 base score of 8.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). A CVSS v4 score has also been calculated for CVE-2025-62630. A base score of 8.7 has been calculated; the CVSS vector string is (AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N). 3.2.3 IMPROPER LIMITATION OF A PATHNAME TO A RESTRICTED DIRECTORY (‘PATH TRAVERSAL’) CWE-22 A vulnerability in a device dependency allows an unauthenticated attacker to read arbitrary files or bypass authentication. CVE-2025-59171 has been assigned to this vulnerability. A CVSS v3 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-2025-59171. 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). 3.2.4 IMPROPER LIMITATION OF A PATHNAME TO A RESTRICTED DIRECTORY (‘PATH TRAVERSAL’) CWE-22 Due to insufficient sanitization, an attacker can upload a specially crafted configuration file to cause a denial-of-service condition, traverse directories, or read/write files, within the context of the local system account. CVE-2025-58423 has been assigned to this vulnerability. A CVSS v3 base score of 8.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). A CVSS v4 score has also been calculated for CVE-2025-58423. A base score of 8.7 has been calculated; the CVSS vector string is (AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N). 3.3 BACKGROUND CRITICAL INFRASTRUCTURE SECTORS: Information Technology COUNTRIES/AREAS DEPLOYED: Worldwide COMPANY HEADQUARTERS LOCATION: Taiwan 3.4 RESEARCHER Alex Williams of Pellera Technologies reported this vulnerability to CISA.
4. MITIGATIONS Advantech has stated that the listed products are end-of-life, and recommends all users upgrade their devices to DeviceOn, which is not vulnerable to these vulnerabilities. For further questions or upgrade assistance, users should contact Advantech. 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.
