The server.info attribute contains the name of the application service. This value is presented to Tomcat clients when clients connect to the tomcat server.
Altering the server.info attribute may increase the complexity for attackers to determine which vulnerabilities affect the server platform.
Perform the following to determine if the server.info value has been changed. Extract the ServerInfo.properties file and examine the server.info attribute.
$ cd $CATALINA_HOME/lib
$ jar xf catalina.jar org/apache/catalina/util/ServerInfo.properties
$ grep server.info org/apache/catalina/util/ServerInfo.properties
Perform the following to alter the server platform string that gets displayed when clients connect to the tomcat server.
