ColdFusion (2023 release) Update 16

Security recommendations

For all security updates, Adobe recommends applying the security configuration settings outlined on the ColdFusion Security page and reviewing the respective Lockdown guides.
Note:
The updates below are cumulative and contain all updates from previous ones. If you are skipping updates, you can apply the latest update, not those you are skipping. Further, you must take note of any changes that are implemented in each of the updates you are skipping.
View ColdFusion (2023 release) Updates for more information.

What's new and changed

ColdFusion (2023 release) Update 16 (release date, 9 September, 2025) addresses an important security fix related to critical path traversal.
View the security bulletin, APSB25-93, for more information.
Note:
If you have added custom entries to the pathfilter.json file for scheduled task output file allowlisting, you must either:
  • Back up the pathfilter.json file before applying the update, or
  • Restore it from the update backup after applying the update.
The backup copy of the file can be found at: hf-updates\hf-2023-00016-330828\backup\lib\pathfilter.json

Changes to serialfilter

With this update, the serialfilter.txt file present in cfusion/lib will be replaced. So if you already have custom entries added to the file, copy the custom entries from the backup file (cfusion/hf-updates/{version}/backup/lib).

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.

ColdFusion JDK flag requirements

COLDFUSION 2023 (version 2023.0.0.330468) and above

For Application Servers

On JEE installations, set the following JVM flag, " -Djdk.serialFilter= !org.mozilla.**;!com.sun.syndication.**;!org.apache.commons.beanutils.**;!org.jgroups.**;!com.sun.rowset.**; !com.mysql.cj.jdbc.interceptors.**;!org.apache.commons.collections.**;", in the respective startup file depending on the type of Application Server being used.
For example:
  • Apache Tomcat Application Server: edit JAVA_OPTS in the ‘Catalina.bat/sh’ file
  • WebLogic Application Server: edit JAVA_OPTIONS in the ‘startWeblogic.cmd’ file
  • WildFly/EAP Application Server: edit JAVA_OPTS in the ‘standalone.conf’ file
Set the JVM flags on a JEE installation of ColdFusion, not on a standalone installation.

Installation

ColdFusion Administrator

In Package Manager > Packages, click Check for Updates in Core Server.
After it detects an update, click Update. The core package gets updated the the latest update.
All installed packages also get updated.
Restart ColdFusion for the changes to take effect.

Install the update in offline mode manually

  1. Download the hotfix installer from the link.
  2. Download the packages zip file from this link and extract its contents to a location accessible to all ColdFusion server instances.
  3. Update "packagesurl" in cfusion/lib/neo_updates.xml of cfusion and all its child instances to point to <InstallerRepositoryUnzippedPath>/bundles/bundlesdependency.json present inside the downloaded folder.
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 <InstallerRepositoryUnzippedPath>\bundles\updateinstallers\hotfix-016-330828.jar
  • Linux-based platforms:<cf_root>/jre/bin/java -jar  <InstallerRepositoryUnzippedPath>/bundles/updateinstallers/hotfix-016-330828.jar
If the core server hotfix installation is successful and if there are errors or issues with packages, packages can be installed/updated from the package manager client(cfusion\bin\cfpm.bat|cfpm.sh).
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 manually updating the application, see the help article.
Note:
If you are on Java 17.0.8 or higher and want to apply the Hotfix manually, use the flag java -Djdk.util.zip.disableZip64ExtraFieldValidation=true -jar hotfix.jar.
However, if you are applying the update from the Administrator, you do not require any flag.

Post installation

Note:
After applying this update, the ColdFusion build number should be 2023,0,16,330828

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-2023-00016-330828/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-2023-00016-330828}/backup directory to {cf_install_home}/{instance_name}/
