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.
Warning:
Check if you need to create and configure connectors after installing the update. View the section Connector Configuration Table for more information.
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.
To install previous updates, see ColdFusion (2021 release) updates.
What's new and changed
ColdFusion (2021 release) Update 17 (release date, October 14, 2024) includes bug fixes and enhancements in Administrator, Language, CFSetup, Database, and other areas. The update contains library upgrades, such as netty, ehcache, and so on.
Review the known issues before proceeding with the update.
Note:
After applying the update, we recommend clearing the Felix cache as a workaround for installing the HTMLToPDF package and verifying the Oracle data source.
Whitespace management on all deployments
Efficient whitespace management reduces the file size of the pages that ColdFusion returns to the browser by removing many extra spaces, tabs, and carriage returns that ColdFusion might otherwise persist from the CFML source file.
You can enable or disable whitespaces in ColdFusion from the ColdFusion Administrator (Server Settings > Settings).
What is changing
In this release, ColdFusion allows whitespace management on all deployments. For example, you can allow whitespaces on JEE deployments using the Administrator or Admin APIs.
Using the ColdFusion Administrator
- Launch ColdFusion Administrator.
- Select Server Settings > Settings.
- Select the checkbox Enable Whitespace Management.
Using the Admin API
In the CFIDE.adminapi.runtime class, specify the propertyName as Whitespace in the setRuntimeProperty method.
For example,
cfscript>
// Login is always required. This example uses two lines of code.
adminObj = createObject("component","cfide.adminapi.administrator");
adminObj.login("password"); //CF admin password.
// Instantiate the runtime object.
myObj = createObject("component","CFIDE.adminapi.runtime");
// set whitespace
myObj.setRuntimeProperty("whitespace",true)
// retrieve the property
saveWhitespacesEnabled = myObj.getRuntimeProperty("whitespace")
writeOutput("Is whitespace management enabled: " & saveWhitespacesEnabled & "<br>")
</cfscript>Clientvariable support in CFSetup
Display and set client variables using CFSetup. ColdFusion supports the following settings in client variables:
Client settings
- Default Storage for Client sessions (clientStore)
- PurgeInterval (purgeIntervalInMinutes)

Known issues
- The PDF Services page in ColdFusion Administrator does not load even with the HTMLToPDF package installed. As a workaround, clear the Felix cache (<cf_home>/cfusion/bin/felix-cache).
- The Oracle DataSource verification fails after installing the latest update. As a workaround, clear the Felix cache, and restart ColdFusion.
- An exception occurs when indexing Open Document Format files, such as those with a .odt extension.
ColdFusion JDK flag requirements
COLDFUSION 2021 (version 2021.0.0.323925) 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.**", 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.
Prerequisites
- On 64-bit computers, use 64-bit JRE for 64-bit ColdFusion.
- 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
- For ColdFusion running on JEE application servers, stop all application server instances before installing the update.
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 with the latest update.
All installed packages that needs an update get updated.
Restart ColdFusion for the changes to take effect.
Install the update in offline mode manually
- Download the hotfix installer from the link.
- Download the packages zip file from this link and extract its contents to a location accessible to all ColdFusion server instances.
- Update "packagesurl" in cfusion/lib/neo_updates.xml of cfusion and all its child instances to point to <InstallerReposityUnzippedPath>/bundles/bundlesdependency.json present inside the downloaded folder.
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).
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 <InstallerReposityUnzippedPath>\bundles\updateinstallers\hotfix-017-330334.jar
- Linux-based platforms:<cf_root>/jre/bin/java -jar <InstallerReposityUnzippedPath>/bundles/updateinstallers/hotfix-017-330334.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 with permission 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 11.0.20 or higher and want to apply the Hotfix, 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 2021.0.17.330334.
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-2021-00017-330334/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:
- Delete the update jar from {cf_install_home}/{instance_name}/lib/updates.
- Copy all folders from {cf_install_home}/{instance_name}/hf-updates/{hf-2021-00017-330334}/backup directory to {cf_install_home}/{instance_name}/
