Therefore, the remote web server is unable to communicate with Tomcat.Ĭonfigure each ColdFusion instance with Tomcat IP address so that Tomcat can be accessed over remote connector. For example,īefore installing the update, ColdFusion instance ran on 0.0.0.0 (all interfaces), but now it binds to localhost loopback address. If you have multiple instances, after updating all the instances, copy secret from each instance to workers.properties. Add back any custom changes made to the workers.properties file after reconfiguring the connector.Īfter updating the ColdFusion instance, ColdFusion configures AJP connector in the instance with a random secret.Ĭopy the secret from instance to workers.properties. Microsoft Windows 8.1, Windows 10, Windows Server R2 2012, and Windows Server 2016 users must use the “Run as Administrator” option to launch wsconfig tool at /config/ wsconfig /backup.Windows users can launch the ColdFusion Administrator using Start > All Programs > Adobe > Coldfusion 2018 > Administrator.The update can be installed from the Administrator of a ColdFusion instance or through the command-line option.For any questions related to updates, see this FAQ. Also, Tomcat requires that the AJP connector must be configured with a secret otherwise the AJP connector won't start (unless secretRequired=false is added to the AJP connector in server.xml).įor instructions on how to install this update, see Server Update section. When you are applying this update, we add a random secret to the server.xml AJP connector unless it is already configured. If you are not using any web server and are using an in-built web server configuration, you can completely comment out or remove the AJP connector from the server.xml configuration.īefore this update, the AJP connector could bind all the interfaces (0.0.0.0) on the machine on which ColdFusion runs. From this update, the AJP connector will bind to localhost address (127.0.0.1 or ::1, depends on the machine) by default, if the address attribute is not specified. If you are using a web server or connector configuration set up, you must make sure that the Port and IP address on which the AJP is running is only available to the web server. It is insecure (clear text transmission) and assumes that your network is safe. AJP is a highly trusted protocol and must never be exposed to untrusted clients. A configuration issue with AJP Protocol was fixed in this update which affects ColdFusion 20 along with a few JEE application servers, which use AJP such as Tomcat, JBoss, and Wildfly.ĬoldFusion uses Tomcat as application server and uses AJP connector to allow web servers, such as, IIS and Apache to use AJP Protocol connector for communication.
