View CSAF Summary Successful exploitation of this vulnerability could allow an attacker to cause the application to crash if a maliciously crafted DICOM file is opened. The following versions of Medixant RadiAnt DICOM are affected: RadiAnt DICOM <=2025.2 CVSS Vendor Equipment Vulnerabilities v3 4.3 Medixant Medixant RadiAnt DICOM Out-of-bounds Write Background Critical Infrastructure Sectors: Healthcare and Public Health Countries/Areas Deployed: Worldwide Company Headquarters Location: Poland Vulnerabilities Expand All + CVE-2026-17264 Opening a crafted DICOM file containing malicious JPEG-compressed pixel data triggers an attacker-controlled heap out-of-bounds write, which may allow an attacker to remotely execute arbitrary code. View CVE Details Affected Products Medixant RadiAnt DICOM Vendor: Medixant Product Version: Medixant RadiAnt DICOM: <=2025.2 Product Status: known_affected Remediations Mitigation Users should update to version 2026.1. It is also recommended to open DICOM files only from trusted and reliable sources. Additionally, the application is compiled with exploit mitigation mechanisms enabled, including Control Flow Guard (CFG), Data Execution Prevention (DEP), and Address Space Layout Randomization (ASLR), which significantly reduces the practical exploitability of the issue. https://www.radiantviewer.com/files/RadiAnt-2026.1-Setup.exe Relevant CWE: CWE-787 Out-of-bounds Write Metrics CVSS Version Base Score Base Severity Vector String 3.1 4.3 MEDIUM CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L 4.0 5.3 MEDIUM CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N Acknowledgments banda, oriotie, ax123, jihyeon4725, lacroix, and minzu reported this vulnerability to CISA Legal Notice and Terms of Use This product is provided subject to this Notification (https://www.cisa.gov/notification) and this Privacy & Use policy (https://www.cisa.gov/privacy-policy). Recommended Practices CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability. 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. CISA also recommends users take the following measures to protect themselves from social engineering attacks: Do not click web links or open attachments in unsolicited email messages.
