The Tomcat $CATALINA_HOME/temp directory is used by Tomcat to persist temporary information to disk. It is recommended that the ownership of this directory be tomcat_admin:tomcat. It is also recommended that the permissions on this directory deny read, write, and execute for the world (o-rwx). Rationale: Restricting access to these directories will prevent local users from maliciously or inadvertently affecting the integrity of Tomcat processes.
Solution
Perform the following to restrict access to Tomcat temp directory: Set the ownership of the $CATALINA_HOME/temp to tomcat_admin:tomcat. # chown tomcat_admin:tomcat $CATALINA_HOME/temp Remove read, write, and execute permissions for the world # chmod o-rwx $CATALINA_HOME/temp Default Value: The default permissions of the top-level directories are 770.
