Description
The access logfile format is defined within a Valve that implements the org.apache.catalina.valves.AccessLogValve interface within the /opt/tomcat/server.xml configuration file: The "%r" pattern code is included in the pattern element and logs the first line associated with the event, namely the request method, URL path, query string, and protocol (""" simply specifies a literal double quote). Including the pattern in the log configuration provides useful information about the time of the event which is critical for troubleshooting and forensic investigations.

ℹ️ Check
As an elevated user on the Tomcat server: Edit the $CATALINA_BASE/conf/server.xml file. Review all "Valve" elements. If the pattern= statement does not include "%r", this is a finding. EXAMPLE: <Host name="localhost" appBase="webapps" unpackWARs="true" autoDeploy="false"> ... <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="localhost_access_log" suffix=".txt" pattern="%h %l %t %u "%r" %s %b" /> ... </Host>

✔️ Fix
As a privileged user on the Tomcat server: Edit the $CATALINA_BASE/conf/server.xml file. Modify the <Valve> element(s) nested within the <Host> element(s). Change the AccessLogValve setting to include "%r" in the pattern= statement. EXAMPLE: <Host name="localhost" appBase="webapps" unpackWARs="true" autoDeploy="false"> ... <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="localhost_access_log" suffix=".txt" pattern="%h %l %t %u "%r" %s %b" /> ... </Host> Restart the Tomcat server: sudo systemctl restart tomcat sudo systemctl daemon-reload
