Updates to LiveCycle Data Services

Remote access to the Adobe LiveCycle Data Management feature has been disabled.

To mitigate potential security risks, admins are recommended to first implement access controls to the RMI port via the host or network firewall.

If you want to enable LCDS after installation, follow the steps below:

• Open the file jvm.config and add the flags:
  • -Dcoldfusion.rmi.enable=true
  • -Dcoldfusion.rmi.enablelcds=true
• Launch ColdFusion Administrator and enable the option, Enable Remote Adobe LiveCycle Data Management access., if it is not enabled already.
• Restart ColdFusion.

Updates to JNBridge

In this update, remote access to .NET to Java side for JNBridge has been disabled.

To mitigate potential security risks, admins are recommended to first implement access controls to the JNBridge port via the host or network firewall.

To grant access to the port,

1. Take a back up of the file neo-dotnet.xml (CF_HOME/cfusion/lib).
2. Add the following flags in neo-dotnet.xml:
   1. <var name='hostIP'><string>0.0.0.0</string></var>
      
   2. <var name='ipWhitelist'><string>127.0.0.1;<IP of the machine where the remote .NET service is running></string></var>
3. Restart ColdFusion.

Prerequisites

1. On 64-bit computers, use 64-bit JRE for 64-bit ColdFusion.
2. If the ColdFusion server is behind a proxy, specify the proxy settings for the server to get the update notification and download the updates. Specify proxy settings using the system properties below in the jvm.config for a stand-alone installation, or corresponding script file for JEE installation.
   • http.proxyHost
   • http.proxyPort
   • http.proxyUser
   • http.proxyPassword
3. For ColdFusion running on JEE application servers, stop all application server instances before installing the update.

Installation

For instructions on how to install this update, see  Server Update section. For any questions related to updates, see this FAQ. 

• The update can be installed from the Administrator of a ColdFusion instance or through the command-line option.
• Windows users can launch the ColdFusion Administrator using Start > All Programs > Adobe > Coldfusion 2018 > Administrator.
• Microsoft Windows 8.1, Windows 10, Windows Server R2 2012, and Windows Server 2016 users must use the “Run as Administrator” option to launch  wsconfig  tool at {cf_install_home}/{instance_name}/runtime/bin.
• If you get the following error when installing the update using the Download and Install option, ensure that the folder {cf_install_home}/{instance_name}/hf_updates has write permission: "An error occurred when performing a file operation write on file {cf_install_home}/{instance_name}/hf-updates/hotfix_004.properties".
• The connector configuration files are backed up at {cf_install_home}/config/ wsconfig /backup. Add back any custom changes made to the worker.properties file after reconfiguring the connector.

Installing the update manually

1. Click the link to download the JAR.
2. Execute the following command on the downloaded JAR. You must have privileges to start or stop ColdFusion service and full access to the ColdFusion root directory.

    Windows: <cf_root>/jre/bin/java.exe -jar <jar-file-dir>/hotfix-004-314546.jar

    Linux-based platforms: <cf_root>/jre/bin/java -jar <jar-file-dir>/hotfix-004-314546.jar

Ensure that the JRE bundled with ColdFusion is used for executing the downloaded JAR. For standalone ColdFusion, this must be at, <cf_root>/jre/bin.

Install the update from a user account that has permissions to restart ColdFusion services and other configured webservers .

For further details on how to manually update the application, see the help article.
