1. EXECUTIVE SUMMARY CVSS v4 10.0 ATTENTION: Exploitable remotely/low attack complexity Vendor: Radiometrics Equipment: VizAir Vulnerabilities: Missing Authentication for Critical Function, Insufficiently Protected Credentials
2. RISK EVALUATION Successful exploitation of these vulnerabilities could allow attackers to manipulate critical weather parameters and runway settings, mislead air traffic control and pilots, extract sensitive meteorological data, and cause significant disruption to airport operations, leading to hazardous flight conditions.
3. TECHNICAL DETAILS 3.1 AFFECTED PRODUCTS The following versions of Radiometrics VizAir are affected: VizAir: Versions prior to 08/2025 3.2 VULNERABILITY OVERVIEW 3.2.1 MISSING AUTHENTICATION FOR CRITICAL FUNCTION CWE-306 Radiometrics VizAir is vulnerable to any remote attacker via access to the admin panel of the VizAir system without authentication. Once inside, the attacker can modify critical weather parameters such as wind shear alerts, inversion depth, and CAPE values, which are essential for accurate weather forecasting and flight safety. This unauthorized access could result in the disabling of vital alerts, causing hazardous conditions for aircraft, and manipulating runway assignments, which could result in mid-air conflicts or runway incursions. CVE-2025-61945 has been assigned to this vulnerability. A CVSS v3.1 base score of 10.0 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H). A CVSS v4 score has also been calculated for CVE-2025-61945. A base score of 10.0 has been calculated; the CVSS vector string is (AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H). 3.2.2 INSUFFICIENTLY PROTECTED CREDENTIALS CWE-522 Radiometrics VizAir is vulnerable to exposure of the system’s REST API key through a publicly accessible configuration file. This allows attackers to remotely alter weather data and configurations, automate attacks against multiple instances, and extract sensitive meteorological data, which could potentially compromise airport operations. Additionally, attackers could flood the system with false alerts, leading to a denial-of-service condition and significant disruption to airport operations. Unauthorized remote control over aviation weather monitoring and data manipulation could result in incorrect flight planning and hazardous takeoff and landing conditions. CVE-2025-54863 has been assigned to this vulnerability. A CVSS v3.1 base score of 10.0 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H). A CVSS v4 score has also been calculated for CVE-2025-54863. A base score of 10.0 has been calculated; the CVSS vector string is (AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H). 3.2.3 MISSING AUTHENTICATION FOR CRITICAL FUNCTION CWE-306 Radiometrics VizAir is vulnerable to a lack of authentication mechanisms for critical functions, such as admin access and API requests. Attackers can modify configurations without authentication, potentially manipulating active runway settings and misleading air traffic control (ATC) and pilots. Additionally, manipulated meteorological data could mislead forecasters and ATC, causing inaccurate flight planning. CVE-2025-61956 has been assigned to this vulnerability. A CVSS v3.1 base score of 10.0 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H). A CVSS v4 score has also been calculated for CVE-2025-61956. A base score of 10.0 has been calculated; the CVSS vector string is (AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H). 3.3 BACKGROUND CRITICAL INFRASTRUCTURE SECTORS: Transportation Systems COUNTRIES/AREAS DEPLOYED: Worldwide COMPANY HEADQUARTERS LOCATION: United States 3.4 RESEARCHER Souvik Kandar reported these vulnerabilities to CISA.
4. MITIGATIONS Radiometrics performed updates on all affected systems and resolved these vulnerabilities. No further action is needed on the user’s end. 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.
