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
Deserialization of untrusted data in Microsoft Messaging Queuing Service in Medtronic's Paceart Optima versions 1.11 and earlier on Windows allows an unauthorized user to impact a healthcare delivery organization’s Paceart Optima system cardiac device causing data to be deleted, stolen, or modified, or the Paceart Optima system being used for further network penetration via network connectivity.

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

Deserialization of untrusted data in Microsoft Messaging Queuing Service within Medtronic's Paceart Optima versions 1.11 and earlier allows an unauthenticated attacker to manipulate cardiac device data (delete, steal, modify) or use the compromised system as a pivot point for further network penetration.

MitigationRestrict network access to MSMQ ports, implement network segmentation to isolate the Paceart Optima system, and apply any vendor-supplied patches from Medtronic. Monitor for indicators of compromise and unusual MSMQ traffic patterns.

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. Confirm Paceart Optima is installed
    Check for the presence of the Paceart Optima application directory (typically under C:\Program Files\Medtronic\Paceart Optima or C:\Program Files (x86)\Medtronic\Paceart Optima) or look for Paceart Optima in Windows Add/Remove Programs.
    Affected if The application is installed on the system.
  2. Determine installed Paceart Optima version
    Check the version by looking at the executable properties: right-click on PaceartOptima.exe (or similar executable name in the installation folder), select Properties, and view the Details tab for Product Version. Alternatively, check the Windows Registry under HKLM\SOFTWARE\Medtronic\Paceart Optima for a Version value.
    Affected if The installed version is 1.11 or lower (versions before 1.12).
  3. Verify Microsoft MSMQ is present and running
    Open Services console (services.msc) and look for 'Message Queuing' service status. Or run 'Get-Service MSMQ' in PowerShell. Also check for MSMQ components in Windows Features or via 'Get-WindowsFeature *MSMQ*' if applicable.
    Affected if The MSMQ service is installed and running on the system.
  4. Check for MSMQ network listeners
    Run 'netstat -an | findstr "1801"' to see if MSMQ is listening on port 1801 (default MSMQ port). Also check firewall rules: run 'netsh advfirewall firewall show rule name=all' looking for rules mentioning MSMQ or port 1801.
    Affected if MSMQ is bound to a network-accessible IP address (not localhost-only) and listening on accessible ports.

The system is affected if Paceart Optima version 1.11 or earlier is installed AND MSMQ is enabled and exposed on the network.

Interim mitigation

Restrict network access to MSMQ ports, implement network segmentation to isolate the Paceart Optima system, and apply any vendor-supplied patches from Medtronic. Monitor for indicators of compromise and unusual MSMQ traffic patterns.
