Fix Recommendation

From the Tomcat server as a privileged user:

Edit the /etc/systemd/system/tomcat.service file, and either add or edit the org.apache.catalina.connector.response.ENFORCE_ENCODING_IN_GET_WRITER setting.

Set the org.apache.catalina.connector.response.ENFORCE_ENCODING_IN_GET_WRITER=true

EXAMPLE:
Environment='CATALINA_OPTS -Dorg.apache.catalina.connector.response.ENFORCE_ENCODING_IN_GET_WRITER=true'

Restart the Tomcat server:
sudo systemctl restart tomcat
sudo systemctl daemon-reload

Check Contents

From the Tomcat server as a privileged user, run the following command:

sudo grep -i enforce_encoding /etc/systemd/system/tomcat.service

If there are no results, or if the org.apache.catalina.connector.response.ENFORCE_ENCODING_IN_GET_WRITER is not ="true", this is a finding.
