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.

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

A privilege escalation vulnerability exists in the login.php file upload functionality of MedDream PACS Premium 7.3.3.840. The application fails to properly validate uploaded files, allowing attackers to upload malicious PHP files that can be executed to gain elevated privileges on the system.

MitigationFix the file upload validation in login.php to reject .php files and implement strict allowlist-based validation, combined with proper authentication and authorization checks to prevent privilege escalation.

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. Verify MedDream PACS Server version
    Check the installed version of MedDream PACS Server through the admin interface, about page, or version file in the installation directory
    Affected if The installed version is exactly 7.3.2.840
  2. Locate login.php file upload functionality
    Identify if the login.php file exists in the web accessible directory and contains file upload handling code
    Affected if The login.php file exists and includes file upload processing logic
  3. Check if upload functionality is accessible
    Determine if the file upload endpoint in login.php can be accessed without authentication or with low-privilege credentials
    Affected if The upload functionality is reachable without proper authentication or authorization checks
  4. Test PHP file upload capability
    Attempt to upload a test .php file through the login.php upload mechanism (e.g., using a harmless test file in a controlled test environment)
    Affected if The application accepts and stores uploaded .php files without rejecting them

A user is affected if the MedDream PACS Server version is 7.3.2.840 AND the login.php file upload functionality accepts and allows storage of .php files without proper validation.
