Restrict access to Tomcat context.xml

보통레벨 1자동tomcat

설명

The context.xml file is loaded by all web applications and sets certain configuration options. It is recommended that access to this file properly protect from unauthorized changes. $CATALINA_BASE/conf/context.xml must not match -perm /o+rwx,g+rwx,u+x 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.
