Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
An unauthenticated attacker can read worklist records from a directory outside the intended per-AE worklist storage area. In a multi-area deployment, this can cross departmental or clinic data separation.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

An unauthenticated attacker can exploit a path traversal vulnerability in DICOM worklist storage to read worklist records from directories outside the intended per-Application Entity (AE) storage area, allowing cross-departmental or cross-clinic data access in multi-area deployments.

MitigationImplement strict path canonicalization and validation to ensure all worklist file access is confined to the designated per-AE storage directory, combined with enforcing authentication for worklist queries.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify DICOM worklist storage configuration
    Locate the DICOM configuration file (commonly dcmtk.ini, dcmqrscp.cfg, or similar) and search for worklist-related settings (wlmscp, worklist, StorageArea keywords)
    Affected if Worklist storage is configured and enabled
  2. Verify per-AE storage path settings
    Examine the worklist storage path configuration for each Application Entity (AE) title - check for StorageArea or related path directives
    Affected if Multiple AE titles are configured with separate storage directories
  3. Check for path validation settings
    Inspect configuration for path canonicalization or validation settings that restrict file access to the designated storage area
    Affected if Path validation is absent or disabled in the worklist configuration
  4. Review authentication settings for worklist queries
    Check if authentication is required for worklist queries in the DICOM service configuration
    Affected if Authentication is disabled or optional for worklist operations
  5. Determine DICOM software version
    Run the DICOM service executable with version flag (e.g., dcmqrscp -v, dcmwlmscp -v) or check installed package version
    Affected if Installed version falls within vulnerable version range or is unknown/unpatched

A system is affected if DICOM worklist storage is enabled, the configuration allows access to directories outside the per-AE storage area, and the installed version is unpatched for this path traversal vulnerability.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
