TMA-TOMCAT-10.2

Restrict access to the web administration application

TinggiLevel 1Otomatistomcat

Deskripsi

Limit access to the web administration application to only those with a justified need. server.xml must contain an uncommented RemoteAddrValve (or RemoteCIDRValve) restricting client addresses. 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 -Eq '^Valve[[:space:]].*org\.apache\.catalina\.valves\.Remote(Addr|CIDR)Valve' && echo compliant || echo noncompliant

Output yang diharapkan: compliant

Cara perbaikan

Metode perbaikan: Panduan atau patch infrastruktur

Add <Valve className="org.apache.catalina.valves.RemoteAddrValve" allow="127\.0\.0\.1"/> to the relevant Host/Context in server.xml. Restart Tomcat afterwards.
