Products Affected:

  • Cary UV Workstation Plus v1.1 and v1.2 (G5194AA and G5195AA) 

Temporary Solution:

Until a fix is available, the Apache Software Foundation recommends disabling the JndiLookup class of Log4j. See Procedure for Disabling the JndiLookup class of Log4j.

Fix Information:

Agilent is preparing a software patch with the new version of Apache Log4j released by the Apache Software Foundation. The patch will be released and posted to Agilent SubcribeNet. Subscribed users will receive an email notification.

Procedure for Disabling the JndiLookup class of Log4j

Agilent recommends customers immediately disable the JndiLookup class of Log4j as the recommended mitigation from the Apache Software Foundation (source:

The following procedure has been verified in the Agilent software test lab:

  1. Plan for a brief downtime for the system. Note that this update only requires a restart of the Tomcat web server and not the entire machine.
  2. Backup the file "C:\Program Files (x86)\Agilent Technologies\OpenLAB Data Store\tomcat\webapps\webhorse.war" (or equivalent if installed on a different drive).
  3. On the affected machine, stop the ‘alfrescoTomcat’ service.
  4. Copy the attached zip file to the affected machine and extract the DisableJndiLookup.ps1 and Launcher.bat files to the same location.
  5. Edit 2 lines of DisableJndiLookup.ps1 to the correct path if they are on a different drive:


  1. Right-Click on Launcher.bat and select Run As Administrator.

Note: Running the script a second time will produce an error that the component is not found.

“Remove-Item : Cannot find path 'C:\Program Files (x86)\Agilent Technologies\OpenLAB Data Store\tomcat\webapps\webhorse' because it does not exist. …”

  1. Start the ‘alfrescoTomcat’ service. Note the webhorse folder is recreated automatically.

Note that the Software Verification Tool will fail due to the changed webhorse.war file. Also note that if the Cary UV Workstation Plus software is reinstalled, this procedure will need to be repeated.

Cary UV Workstation Plus users should not observe any change in system operation. No functionality is affected by disabling the JndiLookup class.
