SV-100803r1_rule tc Server HORIZON must disable the shutdown port.

Vulnerability discussion

An attacker has at least two reasons to stop a web server. The first is to cause a DoS, and the second is to put in place changes the attacker made to the web server configuration. As a Tomcat derivative, tc Server uses a port (defaults to 8005) as a shutdown port. If enabled, a shutdown signal can be sent to tc Server through this port. To ensure availability, the shutdown port should be disabled.

Check content

At the command prompt, execute the following command: grep base.shutdown.port /opt/vmware/horizon/workspace/conf/catalina.properties If the value of "base.shutdown.port" is not set to "-1" or is missing, this is a finding.

Fix text

Navigate to and open /opt/vmware/horizon/workspace/conf/catalina.properties. Navigate to the "base.shutdown.port" setting. Add the setting "base.shutdown.port=-1" to the "catalina.properties" file.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
