Disable the Shutdown port

SedangLevel 2Otomatistomcat

Deskripsi

Tomcat listens on TCP port 8005 to accept shutdown requests. By connecting to this port and sending the SHUTDOWN command, all applications within Tomcat are halted. The shutdown port is not exposed to the network as it is bound to the loopback interface. If this functionality is not used, it is recommended that the shutdown port be disabled. The Server element in server.xml must have port="-1". 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.

Cara pemeriksaan

Metode audit: Perintah shell

shell

B=${CATALINA_BASE:-/opt/tomcat}; H=${CATALINA_HOME:-$B}; O=${TOMCAT_OWNER:-tomcat_admin}; G=${TOMCAT_GROUP:-tomcat}; x(){ [ -r "$1" ] || return 1; awk 'BEGIN{RS="<!--"} NR==1{print;next} {i=index($0,"-->"); if(i) print substr($0,i+3)}' "$1" | tr '\n\t\r' '   ' | tr '<' '\n'; }; s=$(x "$B/conf/server.xml") || exit 1; printf '%s\n' "$s" | grep -E '^Server[[:space:]]' | grep -Ec 'port[[:space:]]*=[[:space:]]*.-1.' || true

Output yang diharapkan: 1

Cara perbaikan

Metode perbaikan: Panduan atau patch infrastruktur
