Restrict access to $CATALINA_BASE

보통레벨 1자동tomcat

설명

$CATALINA_BASE is the environment variable that specifies the base directory which most relative paths are resolved. $CATALINA_BASE is usually used when there are multiple instances of Tomcat running. It is important to protect access to this in order to protect the Tomcat-related binaries and libraries from unauthorized modification. It is recommended that the ownership of $CATALINA_BASE be tomcat_admin:tomcat. $CATALINA_BASE must not match -perm /o+rwx,g=w and must be owned by $TOMCAT_OWNER:$TOMCAT_GROUP; expects 0 findings. Reads $CATALINA_BASE (default /opt/tomcat) and $CATALINA_HOME (default: $CATALINA_BASE); set them for packaged installs (e.g. CATALINA_BASE=/var/lib/tomcat10, CATALINA_HOME=/usr/share/tomcat10). XML comments are ignored. The expected owner/group are tomcat_admin:tomcat as in the benchmark; override with TOMCAT_OWNER / TOMCAT_GROUP.
