DefaultServlet debug parameter must be disabled.
An XCCDF Rule
Description
<VulnDiscussion>The DefaultServlet serves static resources as well as serves the directory listings (if directory listings are enabled). It is declared globally in $CATALINA_BASE/conf/web.xml and by default is configured with the "debug" parameter set to 0, which is disabled. Changing this to a value of 1 or higher sets the servlet to print debug level information. DefaultServlet debug setting must be set to 0 (disabled).</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
