NOTE:

The security updates referenced in the above Tech Notes require JDK
8u121 or higher (for ColdFusion 2016). Adobe recommends updating
your ColdFusion JDK/JRE to the latest version. Applying the
ColdFusion update without a corresponding JDK update will NOT secure
the server. See the relevant Tech Notes for more details.

as outlined on the ColdFusion Security page as well as review the
respective Lockdown guides.

ColdFusion JDK Requirement

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
