Configure maxHttpHeaderSize

NiedrigStufe 2Automatisierttomcat

Beschreibung

The maxHttpHeaderSize limits the size of the request and response headers defined in bytes. No Connector may raise maxHttpHeaderSize above 8192 bytes (unset means the default 8192). 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.

So wird geprüft

Prüfmethode: Shell-Befehl

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-"} /^Connector[[:space:]]/{v=at("maxHttpHeaderSize"); if(v!="-unset-" && (v+0<1 || v+0>8192)) bad=1} END{print bad?"noncompliant":"compliant"}'

Erwartete Ausgabe: compliant

So wird behoben

Behebungsmethode: Anleitung oder Infrastruktur-Patch

Set maxHttpHeaderSize="8192" on each <Connector> in server.xml. Restart Tomcat afterwards.
