Adobe has released security updates for ColdFusion versions 2016 and 2018. These updates resolve multiple important vulnerabilities that could lead to privilege escalation.
| Product | Update number | Platform |
| ColdFusion 2016 |
Update 15 and earlier version |
All |
| ColdFusion 2018 |
Update 9 and earlier versions |
All |
Adobe categorizes these updates with the following priority rating and recommends users update their installations to the newest versions:

Note:
Adobe recommends updating your ColdFusion JDK/JRE to the latest version of the LTS releases for 1.8 and JDK 11. Applying the ColdFusion update without a corresponding JDK update will NOT secure the server. See the relevant Tech Notes for more details.
Adobe also recommends customers apply the security configuration settings as outlined on the ColdFusion Security page as well as review the respective Lockdown guides.

Adobe would like to thank the following individuals and organizations for reporting the relevant issues and for working with Adobe to help protect our customers:
- Nuttakorn Tungpoonsup & Ammarit Thongthua - Secure D Center Research Team, Secure D Center Co.,Ltd., Sittikorn Sangrattanapitak - Cybersecurity Researcher. (CVE-2020-9672, CVE-2020-9673)
COLDFUSION 2018 HF1 and above
For Application Servers
On JEE installations, set the following JVM flag, "-Djdk.serialFilter= !org.mozilla.**;!com.sun.syndication.**;!org.apache.commons.beanutils.**", 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.
COLDFUSION 2016 HF7 and above
This security update requires ColdFusion to be on JDK 8u121 or higher. Adobe recommends that you must manually update your ColdFusion JDK/JRE to the latest version. In case you do not update the JDK/JRE, simply applying the update would NOT secure the server.
For Application Servers
Additionally, on JEE installations, set the following JVM flag, "-Djdk.serialFilter= !org.mozilla.**;!com.sun.syndication.**;!org.apache.commons.beanutils.**", in the respective startup file depending on the type of Application Server being used.
For example:
On Apache Tomcat Application Server, edit JAVA_OPTS in the ‘Catalina.bat/sh’ file
On WebLogic Application Server, edit JAVA_OPTIONS in the ‘startWeblogic.cmd’ file
On a 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
