CVE-2025-0896 is a critical vulnerability affecting the Orthanc server, specifically versions prior to 1.5.8. The issue arises from the server's failure to enable basic authentication by default when remote access is activated. This oversight can lead to unauthorized access, posing significant risks to organizations that rely on this technology.
With a CVSS score of 9.2, this vulnerability is classified as critical, indicating a high level of risk. The severity is underscored by the potential for attackers to exploit this weakness, which could result in unauthorized control over sensitive systems.
Risk to organizations includes unauthorized access to patient data and other sensitive information, which can compromise confidentiality, integrity, and availability. Therefore, organizations should prioritize patching immediately.
Currently, there are no known exploits for this vulnerability, and it is not included in the Known Exploited Vulnerabilities (KEV) list. However, the potential for exploitation remains a concern, warranting immediate attention.
Organizations utilizing the Orthanc server must take proactive measures to secure their systems against this vulnerability to mitigate the associated risks effectively.
Vulnerability Details
The official description of CVE-2025-0896 states: 'Orthanc server prior to version 1.5.8 does not enable basic authentication by default when remote access is enabled. This could result in unauthorized access by an attacker.' This vulnerability falls under the category of 'CWE-306: Missing Authentication for Critical Function.'
The vulnerability has a CVSS score of 9.2, indicating a critical severity level due to its potential impact on confidentiality, integrity, and availability. It affects all versions of Orthanc prior to the vendor's patch release.
The vulnerability was published on February 13, 2025, highlighting the importance of immediate action for organizations that utilize this server.
Technical Analysis
The root cause of CVE-2025-0896 is the configuration of the Orthanc server, which does not enforce basic authentication by default when remote access is enabled. This presents a significant attack vector as the vulnerability is exploitable over the network.
The attack complexity is low; attackers do not require any privileges or user interaction to exploit this vulnerability. The impact on confidentiality, integrity, and availability is high, as unauthorized access can lead to severe consequences.
Given the nature of the vulnerability, the lack of required privileges and user interaction makes it particularly dangerous. Furthermore, the vulnerability’s classification indicates a high risk potential for organizations deploying the affected versions of the Orthanc server.
Risk & Impact Analysis
The real-world risk associated with CVE-2025-0896 is substantial. Organizations using the Orthanc server are vulnerable to unauthorized access, potentially leading to data breaches and significant operational disruption. The urgency of addressing this vulnerability cannot be overstated; organizations should prioritize patching immediately.
The potential blast radius of this vulnerability is considerable, especially in environments handling sensitive medical data. The critical nature of the vulnerability calls for immediate action to mitigate risks. With a CVSS score of 9.2, organizations need to treat this vulnerability as a top priority.
