ColdFusion (2018 release) Update 13
In ColdFusion, there is no known attack vector that exposes the Log4j exploit.
If you are applying Update 13 without applying Update 8, follow the Post Installation steps mentioned for Update 8.
If you are updating via ColdFusion Administrator:
The minimum update versions are Update 4 or higher for ColdFusion (2018 release), due to a recent change in code signing certificate.
These are mandatory pre-requisites before updating.
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.

What's new and changed
ColdFusion (2018 release) Update 13 (release date, 17 December, 2021) addresses vulnerabilities that are mentioned in CVE-2021-44228 and CVE-2021-45046.
If you had applied the mitigation steps in Log4j vulnerability on ColdFusion, we still strongly recommend that you apply this update.
UPDATE: After applying the December updates, you need to upgrade the Log4j 2.x jars to Log4j 2.17 jars. For more information, see this document.
We are aware of scanners flagging cf-logging.jar as vulnerable. After analyzing the vulnerability, we are confident that ColdFusion installation is safe from any possible attack vectors. Nevertheless, we will be removing the vulnerable classes in the upcoming release.
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
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_013.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
- Click the link to download the JAR.
- 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-013-329786.jar
Linux-based platforms: <cf_root>/jre/bin/java -jar <jar-file-dir>/hotfix-013-329786.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.
Post installation
After applying this update, the ColdFusion build number should be 2018,0,13,329786.
Post installation, you must rebuild or reconfigure your connector.
If you see Error 503 or Error 403 when firing up your websites, see the troubleshooting steps.
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-2018-00013-329786/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-2018-00013-329786}/backup directory to {cf_install_home}/{instance_name}/
