Restrict access to jaspic-providers.xml

SedangLevel 1Otomatistomcat

Deskripsi

Tomcat implements JASPIC 1.1 Maintenance Release B (JSR 196). The implementation is primarily intended to enable the integration of 3rd party JASPIC authentication implementations with Tomcat. JASPIC may be configured dynamically by an application or statically via the $CATALINA_BASE/conf/jaspic-providers.xml configuration file. It is recommended that access to this file properly protect from unauthorized changes. $CATALINA_BASE/conf/jaspic-providers.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.
