CVE-2025-1002 is a medium-severity vulnerability affecting MicroDicom DICOM Viewer version 2024.03. This vulnerability allows attackers in a privileged network position to conduct a man-in-the-middle (MITM) attack by failing to adequately verify the update server's certificate. As a result, they could alter network traffic and deliver malicious updates to users.
The impact of this vulnerability is significant as it could enable unauthorized modifications to server responses, posing risks to the integrity of the application and its users. The CVSS score for this vulnerability is 5.7, indicating that while it is not the highest severity, the potential for exploitation exists, especially in environments with adjacent network access.
Organizations should prioritize patching immediately to protect against this vulnerability. The risk to organizations includes potential unauthorized access to sensitive data and the integrity of network operations. Current exploitability is moderate, with public proof of concept available on GitHub, which means that attackers may leverage this vulnerability in the wild.
Given the nature of the attack, it is imperative for organizations using the affected version of MicroDicom DICOM Viewer to assess their exposure and implement necessary mitigations as part of their security posture.
Vulnerability Details
The vulnerability is characterized by the inability of MicroDicom DICOM Viewer to verify the certificate of the update server adequately. This flaw is classified under CWE-295, indicating a certificate validation issue.
The vulnerability was published on February 10, 2025, and the affected component is the DICOM Viewer version 2024.03. The CVSS version 4.0 score of 5.7 indicates low attack complexity and no privileges required, but active user interaction is necessary to exploit it.
Technical Analysis
The root cause of this vulnerability lies in the inadequate verification of the update server's certificate. Attackers positioned on the same network can intercept traffic, manipulate responses, and push malicious updates to users. The attack vector is adjacent, requiring the attacker to be on the same local network, making it a low complexity exploit.
This vulnerability requires no privileges and necessitates user interaction, such as accepting an update. The integrity impact is rated as high, meaning that the attacker can significantly alter the application's data integrity without detection. However, both confidentiality and availability impacts are noted as none.
Risk & Impact Analysis
The real-world risk associated with CVE-2025-1002 is notable, particularly in environments where MicroDicom DICOM Viewer is used for sensitive medical imaging. If exploited, this vulnerability could compromise patient data integrity and lead to unauthorized access to sensitive medical information. The potential blast radius is substantial as attackers could deliver malicious updates to all users on the same network segment.
Organizations should address this vulnerability as part of their priority patch cycle. The CVSS score of 5.7 indicates a medium urgency for remediation, especially in settings where the DICOM Viewer is integral to operations.
