Technical Analysis

CVE-2022-38765 is a medium-severity vulnerability affecting Canon Medical Informatics Vitrea Vision version 7.7.76.1. The core issue lies in insufficient enforcement of access controls within the application. Specifically, an authenticated user can manipulate the 'patientId' parameter in the 'vitrea-view/studies/search' endpoint to gain unauthorized access to imaging records of other patients. This vulnerability is categorized under CWE-639, which relates to authorization bypass through improper validation of user-supplied input. The vulnerability does not require user interaction beyond authentication, and the attack vector is network-based (AV:N). The complexity to exploit is low (AC:L), and the attacker must have some privileges (PR:L), but no UI interaction is needed. The impact is primarily on confidentiality, as unauthorized users can view sensitive medical imaging data without proper authorization. Integrity and availability are not affected. There are no known exploits in the wild, and no patches or vendor advisories have been linked in the provided information. Given the nature of the vulnerability, it poses a significant risk to patient privacy and compliance with data protection regulations, especially in healthcare environments where such imaging systems are deployed.

Potential Impact

For European organizations, particularly healthcare providers and medical imaging centers using Canon Medical Informatics Vitrea Vision, this vulnerability can lead to unauthorized disclosure of sensitive patient imaging records. This compromises patient confidentiality and may violate GDPR and other regional data protection laws, potentially resulting in legal penalties and reputational damage. The exposure of medical images can also undermine trust in healthcare providers and may be exploited for identity theft or insurance fraud. Since the vulnerability requires authenticated access, insider threats or compromised credentials could be leveraged to exploit this flaw. The lack of integrity and availability impact means that while data is not altered or destroyed, the breach of confidentiality alone is critical in the healthcare context. Additionally, unauthorized access to imaging data could disrupt clinical workflows if exploited at scale, indirectly affecting patient care quality.

Mitigation Recommendations

1. Implement strict access control validation on the server side for all parameters, especially 'patientId', ensuring users can only access records they are authorized to view. 2. Conduct a thorough audit of all endpoints handling patient data to identify and remediate similar authorization bypass issues. 3. Enforce the principle of least privilege for user roles within Vitrea Vision, limiting access to imaging records strictly based on necessity. 4. Monitor and log all access to patient imaging data with anomaly detection to identify unusual access patterns indicative of exploitation attempts. 5. Employ multi-factor authentication (MFA) to reduce the risk of credential compromise leading to exploitation. 6. Engage with Canon Medical Informatics for official patches or updates and apply them promptly once available. 7. Provide targeted training to staff on secure handling of credentials and awareness of insider threat risks. 8. If possible, implement network segmentation to isolate the Vitrea Vision system and restrict access to trusted users and systems only.
