Disabling auto deployment of applications

低レベル 2自動tomcat

説明

Tomcat allows auto deployment of applications while Tomcat is running. It is recommended that this capability be disabled. Every Host element in server.xml must set autoDeploy="false" (the default is true). 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.

チェック方法

監査方法: シェルコマンド

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" | awk 'function at(n,  r){if(match($0,"[[:space:]]" n "[[:space:]]*=[[:space:]]*[\"\047][^\"\047]*")){r=substr($0,RSTART,RLENGTH); sub(/^[^=]*=[[:space:]]*./,"",r); return r} return "-unset-"} /^Host[[:space:]]/{n++; if(at("autoDeploy")!="false") bad=1} END{print (n>0&&!bad)?"compliant":"noncompliant"}'

期待される出力: compliant

修正方法

修正方法: ガイダンスまたは IaC パッチ

Set autoDeploy="false" on each <Host> in server.xml. Restart Tomcat afterwards.
