InformationDiagnostic information, such as that found in the response to a TRACE request, often contains sensitive information that may useful to an attacker. By preventing Tomcat from providing this information, the risk of leaking sensitive information to a potential attacker is reduced.
SolutionPerform the following to prevent Tomcat from accepting a TRACE request:
1. Set the allowTrace attributes to each Connector specified in $CATALINA_HOME/conf/server.xml to false.
<Connector ... allowTrace="false" />
Alternatively, ensure the allowTrace attribute for each Connector specified in $CATALINA_HOME/conf/server.xml is absent.
