What are the fixed defects of Mirth Connect 4.1.0?

  • Channel dependency prompt: The Channel Dependency Dialog in Edit Channel view so that the user can deploy dependent channels at the same time with ease. Before this, the Channel Dependency Dialog was only made available in the Channels view.

  • Rest API channel transformer/filter order: Importing channels in JSON format via the Rest API caused transformer/filter steps to be defective before. This function now uses the sequence number to appropriately order the steps as designed.

  • Java 16+ compatibility: The previous versions of Mirth Connect in Java 16+ while running would have made you encounter errors when using Database Connectors or when using a DatabaseconnectionFactory in your Javascript code. Like the following;
    • Error: java.lang.IllegalAccessError: superclass access check failed: class com.mirth.connect.server.userutil.MirthCachedRowSet (in unnamed module @0x10af9340) cannot access class com.sun.rowset.CachedRowSetImpl (in module java.sql.rowset) because module java.sql.rowset does not export com.sun.rowset to unnamed module @0x10af9340
    • This was because their class MirthCachedRowSet expanded the proprietary class CachedRowSetImpl. In Java 16+ this is not allowed anymore by default.
    • To fix this issue, they updated the implementation of MirthCachedRowSet to no longer expanded  CachedRowSetImpl.

  • Fixed ambiguous timestamps in Mirth Connect administrator: Mirth Connect fixed an ambiguity relating to the timestamps in the Mirth Connect Administrator. Timestamps without the AM/PM label will use the 24-hour format now.

What are the security improvements in Mirth Connect 4.1.0?

Updated libraries: 

  • The log4j library is updated from 1.2.16 to 2.17.2. This is to exploit the new logging methods and eliminate vulnerability issues. The following CVEs have been taken care of by updating log4j libraries.
    • CVE-2022-23305
    • CVE-2022-23302
    • CVE-2021-4104
    • CVE-2019-17571
  • The XStream library is updated to version 1.4.19 to eliminate vulnerability issues found in AWS scans.
  • The Bouncy Castle library is updated to version 1.71 in core connect and all extensions, to eliminate vulnerability issues.  The following CVEs have been taken care of by updating the Bouncy Castle library.
    • CVE-2018-1000180
    • CVE-2018-1000613
  • The Jsch library is updated to version 0.1.55 to settle various issues.

What are the commercial extension improvements?

  • Advanced clustering: A rectification was made where in some situations, role controllers were left running on various nodes after a role moves from one node to another. This resulted in incorrect behavior like the channel queue being active on various nodes even when Guarantee Message Order is enabled.

  • Interoperability connector suite: The interoperability connector suite has updated options to proceed with eHealth Exchange validation standards. This new option is set to yes in the default and contains conditions in the header.

  • Mirth results v2 (CDR) plugin: Issues have been fixed where Mirth results (CDR) dependencies were not pulled down when reloading the resource.
