Title

The ISEC7 SPHERE must remove any unnecessary users or groups that have permissions to the server.xml file in Apache Tomcat. (Cat II impact)

Discussion

Tomcat uses a port (defaults to 8005) as a shutdown port. Someone could Telnet to the machine using this port and send the default command SHUTDOWN. Tomcat and all web apps would shut down in that case, which is a denial-of-service attack and would cause an unwanted service interruption.

Verify no unnecessary users or groups have permissions to the file.
