Adobe has released security updates for ColdFusion versions 2018 and
2016. These updates resolve two critical and one important vulnerability that
could lead to arbitrary code execution.    

Affected Versions

|       Product       |  Affected Versions   |      Platform       |
|ColdFusion 2018      |Update 4 and earlier  |All                  |
|                     |versions              |                     |
|ColdFusion 2016      |Update 11 and earlier |All                  |
|                     |versions              |                     |


Adobe categorizes these updates with the following priority rating and
recommends users update their installations to the newest versions:

|     Product      |Updated Version |Platform |Priority rating |Availability |
|ColdFusion 2018   |Update 5        |All      |2               |Tech note    |
|ColdFusion 2016   |Update 12       |All      |2               |Tech 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

Adobe recommends customers apply the security configuration settings 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

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

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"

On WebLogic Application Server, edit JAVA_OPTIONS in the "startWeblogic.cmd"

On a WildFly/EAP Application Server, edit JAVA_OPTS in the "standalone.conf"

Set the JVM flags on a JEE installation of ColdFusion, not on a standalone
