TMA-TOMCAT-3.1

Set a nondeterministic Shutdown command value

SedangLevel 1Otomatistomcat

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. It is recommended that a nondeterministic value be set for the shutdown attribute in $CATALINA_HOME/conf/server.xml. The Server element in server.xml must not use the default shutdown="SHUTDOWN"; expects 0 matches. 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 'shutdown[[:space:]]*=[[:space:]]*.SHUTDOWN.' || true

Output yang diharapkan: 0
