Jason Gerlowski commented on SOLR-10648:
----------------------------------------

If any users are unswayed by Jan's rationale above (+1, btw) and would like to 
hide sysprops from the Admin UI, then there _is_ a workaround for this.  Users 
can edit {{solr.in.sh}} and define the {{-Dsolr.redaction.system.pattern}} 
sysprop under SOLR_OPTS:

{code}
SOLR_OPTS="$SOLR_OPTS 
-Dsolr.redaction.system.pattern=(.*password.*|.*PORT|.*KEY)"
{code}

(Credit to Jan, who mentioned this on the mailing list)

> Currently anyone with HTTP access to Solr can see the Admin UI and all the 
> system properties. In there you find
> {noformat}
> -DSTOP.KEY=solrrocks
> -DSTOP.PORT=7983
> {noformat}
> This means that anyone with this info can shut down Solr by hitting that port 
> with the key (if it is not firewalled).
> I think the simple solution is to add STOP.PORT and STOP.KEY from 
> {{$SOLR_START_OPTS}} to the {{$SOLR_JETTY_CONFIG[@]}} variable. It will still 
> be visible on the cmdline but not over HTTP.
