Tomcat must be configured to limit data exposure between applications.

Description

<VulnDiscussion>If RECYCLE_FACADES is true or if a security manager is in use, a new facade object will be created for each request. This reduces the chances that a bug in an application might expose data from one request to another. This setting is configured using environment variable settings. For Linux OS flavors other than Ubuntu, use the relevant OS commands. For Ubuntu, this setting can be managed in the /etc/systemd/system/tomcat.service file via the CATALINA_OPTS variable. This setting is defined in the file and referenced during tomcat startup in order to load tomcat environment variables. Technically, the tomcat.service referenced in the check and fix could be called a different name; but for STIG purposes and to provide a standard setting that can be referred to and obviously is used for Tomcat, tomcat.service was chosen.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
