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
The Sante PACS Server allows a remote attacker to crash the main thread by sending a crafted HL7 message, causing a denial-of-service condition. The application would require a manual restart and no authentication is required.

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

Sante PACS Server contains a vulnerability in its HL7 message parsing functionality. An unauthenticated remote attacker can send a specially crafted HL7 message that triggers a crash in the main thread, causing the application to become unavailable. The server requires manual restart to recover normal operation.

MitigationImplement robust input validation and bounds checking on all incoming HL7 message fields before processing. Consider network segmentation to restrict HL7 message sources to trusted systems and implement rate limiting to detect potential abuse. Monitor for repeated crashes as an indicator of attack attempts.

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 installed Sante PACS Server version
    Check the application version through the Sante PACS Server administration interface, or look for version information in the installation directory or registry depending on the deployment method
    Affected if The installed version is lower than 4.2.3
  2. Determine if HL7 listener service is enabled
    Inspect the server configuration to verify whether the HL7 listening service is active and accepting incoming connections. This is typically found in the HL7 server settings or network listener configuration within the Sante PACS administration panel
    Affected if The HL7 listener service is enabled and accessible over the network
  3. Verify network exposure of HL7 port
    Identify the port configured for HL7 communication (commonly port 2575 or 2576) and determine if it is exposed to untrusted networks by reviewing firewall rules or network configuration
    Affected if The HL7 port is reachable from untrusted or external network segments
  4. Check for recent application crashes
    Review application event logs, crash dump files, or service restart history for evidence of unexpected application termination events, particularly those occurring around HL7 message processing
    Affected if Multiple application crashes or unexpected restarts have occurred and correlate with HL7 message activity

The server is affected if it runs a version of Sante PACS Server below 4.2.3 with the HL7 listener service enabled and exposed, as the vulnerability is triggered by receiving specially crafted HL7 messages.

Upgrade available Upgrade to 4.2.3 or later
Fixed in 4.2.3
Interim mitigation

Implement robust input validation and bounds checking on all incoming HL7 message fields before processing. Consider network segmentation to restrict HL7 message sources to trusted systems and implement rate limiting to detect potential abuse. Monitor for repeated crashes as an indicator of attack attempts.

Recommended fix Moderate confidence

4.2.3 or later

  1. 1. Back up the current Sante PACS Server configuration and any critical data
  2. 2. Obtain Sante PACS Server version 4.2.3 or later from the official vendor source
  3. 3. Stop the currently running Sante PACS Server service
  4. 4. Install the upgraded Sante PACS Server version 4.2.3 or later
  5. 5. Restore the configuration from the backup if needed
  6. 6. Start the Sante PACS Server service
  7. 7. Verify the application is running correctly and accepting connections
  8. 8. Test that HL7 message processing is working without crashes
