CVE-2024-33606

An attacker could retrieve sensitive files (medical images) as well as plant new medical images or overwrite existing medical images on a MicroDicom DICOM Viewer system. User interaction is required to exploit this vulnerability.

Weakness

The product uses a handler for a custom URL scheme, but it does not properly restrict which actors can invoke the handler using the scheme.

Affected Software

Potential Mitigations

• Utilize a user prompt pop-up to authorize potentially harmful actions such as those modifying data or dealing with sensitive information.
• When designing functionality of actions in the URL scheme, consider whether the action should be accessible to all mobile applications, or if an allowlist of applications to interface with is appropriate.
