The server.number attribute represents the specific version of Tomcat that is executing. This value is presented to Tomcat clients when they connect.
Advertising a valid server version may provide attackers with information useful for locating vulnerabilities that affect the server platform. Altering the server version string may make it harder for attackers to determine which vulnerabilities affect the server platform.
Perform the following to determine if the server.number value has been changed:
$ cd $CATALINA_HOME/lib
$ jar xf catalina.jar org/apache/catalina/util/ServerInfo.properties
$ grep server.number org/apache/catalina/util/ServerInfo.properties
Perform the following to alter the server version string that gets displayed when clients connect to the server.
$ cd $CATALINA_HOME/lib
$ jar xf catalina.jar org/apache/catalina/util/ServerInfo.properties
$ cd org/apache/Catalina/util
Open ServerInfo.properties in an editor
Update the server.number attribute:
server.number=<someversion>
$ jar uf catalina.jar org/apache/catalina/util/ServerInfo.properties
The default value for the server.number attribute is a four part version number, such as 5.5.20.0.
