| 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. |

| 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> |

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 |
