Use the logEffectiveWebXml and metadata-complete settings for deploying applications in production

DüşükDüzey 1Otomatiktomcat

Açıklama

Both fragments and annotations give rise to security concerns. web.xml contains a metadata-complete attribute on the web-app element whose binary value defines whether other sources of metadata should be considered when deploying this web application, this includes annotations on class files (@WebServlet, but also @WebListener, @WebFilter, …), web-fragment.xml as well as classes located in WEB-INF/classes. Counts applications whose WEB-INF/web.xml lacks metadata-complete="true" or whose META-INF/context.xml lacks logEffectiveWebXml="true"; expects 0. 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.
