ColdFusion (2018 release) Update 16

ColdFusion (2018 release) Update 16 (release date, 14 March, 2023) addresses vulnerabilities that could lead to arbitrary code execution, arbitrary file system read, and memory leak.

For more information, security bulletin APSB23-25.

New jvm flags

In this update, we've disabled cfclient by default. If you need to enable it, there is a new flag to do it.

• -Dcoldfusion.cfclient.enable=true/false
  

Doing so will enable cfclient, but will allow only CFCs to be read. To allow other files to be read, use the flag listed below:

• -Dcoldfusion.cfclient.allowNonCfc=true/false

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.
• Windows 10, Windows Server R2 2012, and Windows Server 2019 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_015.properties".
• The connector configuration files are backed up at {cf_install_home}/config/ wsconfig /backup. Add back any custom changes made to the workers.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-016-330130.jar

    Linux-based platforms: <cf_root>/jre/bin/java -jar <jar-file-dir>/hotfix-016-330130.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 permission to restart ColdFusion services and other configured webservers .

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

Post installation

After applying this update, you must reinstall any custom hotfixes that might have been applied earlier. The hotfixes are located in the folder /ColdFusion2018/cfusion/hf-updates/hf-2018-00016-330130
/backup/lib/updates.

Uninstallation

To uninstall the update, perform one of the following:

• In ColdFusion Administrator, click Uninstall in Server Update > Updates > Installed Updates.
• Run the uninstaller for the update from the command prompt. For example, java -jar {cf_install_home}/{instance_home}/hf_updates/hf-2018-00016-330130/uninstall /uninstaller.jar

If you can't uninstall the update using the above-mentioned uninstall options, the uninstaller could be corrupted. However, you can manually uninstall the update by doing the following:

1. Delete the update jar from {cf_install_home}/{instance_name}/lib/updates.
2. Copy all folders from {cf_install_home}/{instance_name}/hf-updates/{hf-2018-00016-330130}/backup directory to {cf_install_home}/{instance_name}/
