| Description |
|---|
| An attacker has at least two reasons to stop a web server. The first is to cause a denial of service, and the second is to put in place changes the attacker made to the web server configuration. If the Tomcat shutdown port feature is enabled, a shutdown signal can be sent to the Security Token Service through this port. To ensure availability, the shutdown port must be disabled. |
| ℹ️ Check |
|---|
| At the command prompt, run the following command: # grep 'base.shutdown.port' /usr/lib/vmware-sso/vmware-sts/conf/catalina.properties Expected result: base.shutdown.port=-1 If the output of the command does not match the expected result, this is a finding. |
| ✔️ Fix |
|---|
| Navigate to and open: /usr/lib/vmware-sso/vmware-sts/conf/catalina.properties Add or modify the following setting: base.shutdown.port=-1 Restart the service with the following command: # vmon-cli --restart sts |
