ColdFusion (2023 release) Update 1

ColdFusion (2023 release) Update 1 (release date, 11 July, 2023) addresses vulnerabilities that are mentioned in the security bulletin, APSB23-40. These updates resolve critical and important  vulnerabilities that could lead to arbitrary code execution and security feature bypass.

We have also updated the lockdown installer for the version in this update. This addresses a security issue. To apply this fix, you should download and install the lockdown installers from Download 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.

Known issues in this release

The Administrator > Security > Allowed IP Address depends on the debugger package. You should install the debugger package if you want to use the functionality.

ColdFusion JDK 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.**", 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.

    Windows: <cf_root>/jre/bin/java.exe -jar <jar-file-dir>/hotfix-001-330480.jar

    Linux-based platforms: <cf_root>/jre/bin/java -jar <jar-file-dir>/hotfix-001-330480.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.

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:
