Adobe Coldfusion versions 2016 (update 16 and earlier), 2018 (update 10 and earlier) and 2021.0.0.323925 are affected by an Improper Neutralization of Input During Web Page Generation (‘Cross-site Scripting’) vulnerability. An attacker could abuse this vulnerability to execute arbitrary JavaScript code in context of the current user. Exploitation of this issue requires user interaction.
COLDFUSION 2021 (version 2021.0.0.323925) 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 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
