Fix Recommendation

Navigate to and open:

/usr/lib/vmware-sso/vmware-sts/conf/server.xml

Inside the <Host> node, find the "AccessLogValve" <Valve> node and replace the "pattern" element as follows:

pattern="%t %I [Request] &quot;%{User-Agent}i&quot; %{X-Forwarded-For}i/%h:%{remote}p %l %u to local %{local}p - &quot;%r&quot; %H %m %U%q [Response] %s - %b bytes [Perf] process %Dms / commit %Fms / conn [%X]"

Restart the service with the following command:

# vmon-cli --restart sts

Check Contents

At the command prompt, run the following command:

# xmllint --xpath '/Server/Service/Engine/Host/Valve[@className="org.apache.catalina.valves.AccessLogValve"]/@pattern' /usr/lib/vmware-sso/vmware-sts/conf/server.xml

Example result:

pattern="%t %I [Request] &quot;%{User-Agent}i&quot; %{X-Forwarded-For}i/%h:%{remote}p %l %u to local %{local}p - &quot;%r&quot; %H %m %U%q [Response] %s - %b bytes [Perf] process %Dms / commit %Fms / conn [%X]"

Required elements:

%h %{X-Forwarded-For}i %l %t %u &quot;%r&quot; %s %b

If the log pattern does not contain the required elements in any order, this is a finding.
