Assessment Title

Rule Text

The shutdown port must be disabled.

Description

Discussion Text

Tomcat listens on TCP port 8005 to accept shutdown requests. By connecting to this port and sending the SHUTDOWN command, all applications within Tomcat are halted. The shutdown port is not exposed to the network as it is bound to the loopback interface. Set the shutdown attribute in $CATALINA_BASE/conf/server.xml.

Assessment Procedure

Check Text

From the Tomcat server run the following OS command:

$ sudo grep -i shutdown $CATALINA_BASE/conf/server.xml

Ensure the server shutdown port attribute in $CATALINA_BASE/conf/server.xml is set to -1. 

EXAMPLE:
<Server port="-1" shutdown="SHUTDOWN">

If Server port not = "-1" shutdown="SHUTDOWN", this is a finding.

Implementation Procedure

Fix Text

From the Tomcat server as a privileged user, edit the $CATALINA_BASE/conf/server.xml file: set the Server port setting to -1 and restart the Tomcat server.

<Server port="-1" shutdown="SHUTDOWN">

sudo systemctl restart tomcat
sudo systemctl daemon-reload
