Adobe has released security updates for ColdFusion versions 2018, 2016 and 11. These updates resolve a critical vulnerability that could lead to arbitrary code execution in the context of the running ColdFusion service.
Adobe is aware of a report that CVE-2019-7816 has been exploited in the wild.
Product | Affected Versions | Platform |
---|---|---|
ColdFusion 2018 | Update 2 and earlier versions | All |
ColdFusion 2016 | Update 9 and earlier versions | All |
ColdFusion 11 | Update 17 and earlier versions | All |
Note:
Note: This attack requires the ability to upload executable code to a web-accessible directory, and then execute that code via an HTTP request. Restricting requests to directories where uploaded files are stored will mitigate this attack.

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
COLDFUSION 11 HF15 and above
This security update requires ColdFusion to be on JDK 7u131 or 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 J2EE 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
