$CATALINA_BASE/temp/ folder must be owned by tomcat user, group tomcat.
An XCCDF Rule
Description
<VulnDiscussion>Tomcat file permissions must be restricted. The standard configuration is to have all Tomcat files owned by root with group Tomcat. While root has read/write privileges, group only has read permissions, and world has no permissions. The exceptions are the logs, temp, and work directories that are owned by the Tomcat user rather than root. This means that even if an attacker compromises the Tomcat process, they cannot change the Tomcat configuration, deploy new web applications, or modify existing web applications. The Tomcat process runs with a umask of 0027 to maintain these permissions. If operational needs require application administrators to be able to change application configurations, the group permissions can be modified to allow specific application admins the access they require with an ISSM risk acceptance. Ownership may not change. The exposure of the system to high risk networks should always be taken into account.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
